When Zoë Boehm agrees to track down the gang who knocked over Sweeney's jewellery shop, she's just hoping to break even in time for tax season. She certainly doesn't expect to wind up in a coffin. But she's about to become entangled with a strange collection of characters, starting with suicidal Tim Whitby, who's dedicating what's left of his life to protecting the pretty, battered Katrina Blake from her late husband's sociopathic brothers, Arkle and Trent.

Unfortunately for Zoë, Arkle has a crossbow, Tim has nothing left to lose, and even Katrina has her secrets. And death, like taxes, can't be avoided forever.

Another excellent book by this great author. (Hope we get another in the Slough House series soon though!)

Why We Die was an interesting read. There were parts which were quite slow and then there were parts that were so tense I had to put the book down for a moment. With Herron you can never rely on what will happen to people - he kills off prominent characters at the drop of a hat. There were parts which were very amusing too, the usual black humour plus some activities and violence which verged on being slapstick.

The mystery of the missing money was convoluted and had quite a twist at the end which I did not see coming. Very entertaining and I am looking forward to book 4.

Why We Die is the third book in the Oxford Investigations series by British author, Mick Herron. The story starts with a widower, a debt-ridden PI and a bunch of thugs. Arkle, Baxter and Trent have decided they can make easy money, just not in the family gravel business. Tim Whitby, still grieving the loss of his wife, checks into a hotel, planning to check out (of life) but is distracted by a bruised-looking Katrina Blake.

And Zoë Boehm’s old red Nissan Sunny is stolen and set on fire, something arranged by someone she’s recently upset, meaning she has to resort to a borrowed orange VW beetle for transport. The same someone also arranged scrutiny of her finances by Inland Revenue, resulting in a bill of almost five thousand pounds, forcing her to take on an investigation for a crooked robbery victim.

Some tedious surveillance and an encounter with an unusual chauffeur gives Zoë the information she needs, but her interest is piqued, and she heads to Totnes to dig a little deeper. While there, she finds herself rescuing Tim Whitby from a crossbow-wielding Arkle with an apple.

In the action that follows, Zoë effects another rescue, is rescued twice herself, climbs up a wall, brandishes a chair, assists more than one assailant downstairs, kicks and king-hits, is knocked out by a torch and ends up shut inside a freezer. Several people are stabbed and the crossbow gets quite a workout. The hood ornament of a hearse plays an important part, and several people are seeking a certain bag with a lot of money in it.

As usual, Herron gives the reader a plot with some great twists and, of several red herrings, one that will have readers familiar with his style wondering if he has indulged in his tendency to kill off a regular character without qualm or hesitation. Fans will be eager for the fourth and final book of the series, Smoke and Whispers. Excellent British crime fiction.

I think this is my first 4 star Herron. Losing a star may be more about my preferences than about the writing, which remains solid and suspenseful. This book really doesn't feature the protagonist. She is there, she has a role, but she's absent more than present and the real cat and mouse game only involves her occasionally.

Since this is a book about a set of bad guys, pseudo bad guys, pseudo good guys, and their relationships with each other, I would have liked to enjoy all that time spent with them more than I did. Most of the bad guys, especially the prime one, were plenty scary but still flat. It got old. And there was more violence here than usual. It's just a grittier novel, which isn't necessarily bad, but it felt a little one-off, and wasn't as enjoyable for me as his others.

Mick Herron wrote his four "Oxford Investigations" books (of which this is the third) before coming up with the brilliant "Slough House" and its cast of "slow horses"…and the rest, of course, is literary — and now television — history.

That said, this book is a really nice (if slightly over-plotted) mystery, and it's obvious that Herron had already developed the writing chops and ear for dialogue that would transition seamlessly into his "Slough House" stories. Zoë Boehm is a great — if not completely original — character, and I also loved Win, who I can only hope returned in the fourth/final "Oxford" book, (and then someday maybe even crosses over into the "SH" universe?).

I (and probably any other American readers) first encountered Zoë in Herron's short story collection, Dolphin Junction : Stories, where she and husband Joe Silvermann work together as PIs. However, by this book (and as best as I can tell, in the previous two as well), Joe has died and so Zoë is now working on her own. I frankly had no idea that Oxford was that large — or crime-ridden — a city!

All these books are only recently hitting American bookstores, based on the wild success of the "Slough House" series, but haven't yet found our library shelves; will have to try our local's "Suggest a Title" function. Meanwhile, I plan to revisit Dolphin Junction and reread those stories,* now that I have a better feel for Zoë, (who as a short story character, was less developed there than she is here).

In looking at Herron's overall output, I also see that in the midst of writing the "Oxford" books, he also wrote a standalone called Reconstruction, which features Bad Sam Chapman and the "Dogs" years before "Slough House" came out, in which later books he plays a semi-regular character — so will now have to look for that one as well, to tide me over until Herron's newest, Clown Town, comes out this fall.

* UPDATE: And so I already DID reread those four stories in Dolphin, and to my surprise, the first three were really Joe Silvemann stories with Zoë as just a peripheral and frankly (IMHO) unsympathetic character; apparently hard-edged, on-her-own Zoë is more appealing than unhappily married and sarcastic/cranky Zoë, (although bear in mind this is a man's take here; female readers may see her differently). And then the fourth story was a direct sequel to this book, in which Joe was already dead and Win indeed does reappear as a major character — although again, hopefully we'll still see yet more of her in books to come.

I'm really liking Zoe Boehm more and more for each new book I read in this series. Her job sounds a little boring - as a PI, she "finds people" - but along the way, she does a lot more. She's smart and resourceful, single-minded and brave. It's always nice to read about heroes that aren't overly macho and unrealistic.

This one was pretty complex and surprising. There was a lot going on, but a lot of it was not what it seemed. I'm pretty sure this could be read without reading the earlier books in the series, but it helps if you read them.

A better story than the previous novel but I still can't get along with the ever-prevaricating Ms Boehm. She simply drives me nuts. Get on with it, I shout at the book, but she never does.

The story is that Zoe is employed to look for the men who robbed a jewellers of stock that cannot be claimed for on the insurance. Simple enough. However although Zoe finds the culprits, the case begins quickly to spiral out of control leaving anyone and everyone in danger.

I say this is a better story except for one fundamental problem and that is if Zoe had simply told the client who the culprits were absolutely none of the following story would have happened. Maybe that's the case for a lot of stories but Zoe Boehm is a PI. She's wasting her own time, which seems to me to be a commodity she can't afford to throw away since she's irritated some vengeful people, has no money and apparently no desire to get a different job.

The ending was satisfying though.

This is Mick Herron, so there’s no fault in the writing, but it just lacked the “spark” that his others have had. I also got the feeling throughout that he is about as tired of Zoe as this reader is. Felt like he had to work to write it, and I know I had to work to read it.

Setting: Oxford/Totnes, Devon/London.
This is the third book featuring private investigator Zoe Boehm. With debts mounting and a recent demand for back tax from HMRC, Zoe is desperate for work. After an armed robbery at an Oxford jewellery store, Zoe is asked by the owner to discover the identity of the thieves - as much of the inventory stolen should not even have been in his possession, as he had been persuaded by a local criminal to act as a 'fence' and custodian of stolen items, he cannot reveal all to the police. Zoe is also being hounded by former police officer Bob Holland, who lost his job owing to Zoe's actions in the previous book, and his vengeance shows no sign of ending. As Zoe becomes more entangled with the case, she gets involved with several unusual characters - the suicidal Tim Whitby (who chanced on a meeting with a woman called Katrina Blake, married to one of the robbers and apparently being battered by him) and the other members of the gang, brothers Arkle and Trent Dalton (who take violence to a whole new level, particularly Arkle who likes using his crossbow!). Zoe once again ends up putting her life on the line in trying to bring the gang to justice whilst also trying to protect Katrina and Tim. But Katrina may not be as innocent as she seems....
Another great story from this series - always on the look-out for more although I do prefer the Slough House novels. Loved the sections set in Totnes as I am quite familiar with the town from holidays in Devon. Several unexpected twists and turns in this story make it a gripping and exciting read - 9/10.

The most assured of the Zoë Boehm thrillers so far. With even more Herron than in the previous two, this one begins to show his trademark humor and talent for intriguing, complicated characters.

Mick Herron's 'Why We Die', the 3rd in his Oxford Investigations series, is a clever mystery that leads us down a path that has a bit of an abrupt departure at the end. Walking, running, and driving that path isn't a bunch of laughs to begin with, as it's lined with various criminals, sociopaths, a physical freak, murderers, and simpletons, but the journey is worthwhile for the reader.

The series stars the indefatigable Zoe Boehm, private investigator of a certain age, who just won't give up once she latches onto something. In 'Why We Die', she's hired by a dodgy pawn shop owner to find out who robbed him. Although the police are likewise investigating the robbery, he couldn't necessarily divulge to them all that was stolen from him because, well, most of it was stolen property he was fencing. That's why he needs Zoe. Zoe needs him because she has a big tax bill to settle up on and needs a payday. Oh yeah, and during the robbery a bystander was shot....with a crossbow. That's important in the action that follows.

Coincidentally, at about the same time a young man who intends to commit suicide due to the depression he's felt after his wife died in an accident sits in a bar getting hammered. He's approached by a beautiful young lady who appears to have been battered by someone, they enjoy a bit of a chat, and he continues his drinking while wondering who could've abused her. He returns home, drinks himself into a stupor, and forgets to off himself.

In relatively short order, with the help of a freakishly-built young lady who's 'on the inside', Zoe determines who did the robbery, but complications arise. The leader of the 'gang' dies after being stabbed by his abused wife, he was the financial guy for the group and had hidden all the loot, and lots of players are trying to locate the spoils. The abused wife has been arrested but is getting the 'abused wife' treatment from the police and the press, but the rest of the gang, including the psycho leader who is a cross-bow aficionado, thinks she knows where the loot is stashed. In the meantime, our erstwhile suicidal guy, not the sharpest tool in the shed, begins his quest to locate the abused young lady who he'd conversed with at the bar. I won't go any farther on the plot.....

I've grown to really enjoy the Zoe Boehm character through the course of this series. She's smart, glib, fearless often to the point of recklessness, physical, a bit older than you'd think.... in short, a complex personality that's been expertly developed by the author. Herron's a tremendous writer, particularly with dialogue and understated Brit humor, and he creates plots that'll keep moving forward with a lot of quirks thrown in for good measure. His Slough House series is great and these Oxford mysteries are excellent as well. Both series are character-driven and totally enjoyable.

Phew, tough slog. Very depressing, droning reading until near the end when it finally picks up and becomes good, classic Mick Herron, suspenseful and well thought out. But getting there without slitting your wrists ... Difficult. Put it down many times, pretty depressing writing for the majority of the book.

Mick Herron is a recent and very welcome discovery for me, but Why We Die is a rare disappointment. Not worth my effort for now, may return to it when I'm finished with all available Herrons.

This series has got better and better with each successive book. This one was horribly tense but it's a superb read. Great characters and storyline, with Herron's usual smattering of 'sadness'.

The weakest of the Mick Herron book’s I’ve read so far. Something about this book just grated and I’m not sure why, anyway it took ages for me to read because I kept putting it down.

There were a lot of different story threads in Why We Die. All of these threads were in some way connected to Zoë Boehm. I own a copy of Dolphin Junction (an Oxford Investigations short story collection) but I will likely read the 4th book (Smoke and Whispers) next before reading the short stories.

SUMMARY: The road to hell is paved with all sorts of intentions, as Oxford private investigator Zoë Boehm discovers when a straightforward jewelry store robbery turns out to be anything but. When Zoë Boehm agrees to track down the gang who knocked over Sweeney’s jewelry shop, she’s just hoping to break even in time for tax season. She certainly doesn’t expect to wind up in a coffin. But she’s about to become entangled with a strange collection of characters, starting with suicidal Tim Whitby, who’s dedicating what’s left of his life to protecting the pretty, battered Katrina Blake from her late husband’s sociopathic brothers, Arkle and Trent. Unfortunately for Zoë, Arkle has a crossbow, Tim has nothing left to lose, and even Katrina has her secrets. And death, like taxes, can’t be avoided forever.

That most overused word unputdownable could have been coined with Mick Herron in mind. I’ve yet to read a book by him that hasn’t been compulsively readable to the exclusion of everything else that I’m supposed to be getting on with. Whether it’s the flawed humanity of his characters trying to do their best in an imperfect world, his dark and twisted humour, his snappy, twisty-turny plots, or the relentless pace of his narrative, his books are almost impossible for the reader to tear themselves away from.
Why We Die is classic Herron; third in the quartet of books featuring the Oxford private detective Zoe Boehm, it has a plot with so many about turns and narrative tricks (with one massive shock coming just before the end) that it’s almost impossible to describe. Ms Boehm is a great character, and it seems a shame that there is only one more book in the series. Let’s hope Mick Herron revisits her at some point.

I've enjoyed going back and reading these proto-Herron stories. They don't quite have the zip of the Slough House books but there are other recognizable elements and the same dark disregard for the deaths of peripheral characters. I would love to ask him one day why Zoe and Joe were Jewish. It's barely addressed and only seems to stand as a metaphor for outsider-ness which might feel exploitative if it ever really became a plot point. Three books in and it still seems like a red herring.

Only one more of these to go, unless he ever returns to the series. They make a nice distraction, but they haven't really risen beyond that.

Another excellent read. For some reason I thought this was a trilogy but it’s not. This is the third book out of four. Characters in the story are developing nicely. It really is an excellent thriller. I’ve downloaded the fourth and final book in the series. Looking forward to it.
There is realism in the writing. The main character has car issues which causes practical problems continuing the investigation.
You just know the James Bond never has car trouble. Real world thriller.

Zoe Wins? Maybe not

I have read a number of Mick Herein books, in particular the "Slow Horses" series. This like those is his particular style which are hard to get into but once you do they are difficult to put down. His meandering style causes you to switch from character to character, sometimes losing track of the thrust of the story. In this adventure Zoe is hired to find out who stole, stolen jewelery from her client. This becomes a real trail to follow, which Zoe eventually follows to the culmination

This author is so great. I love the characters that he creates along with their dialogue. He combines intrigue with violence and humor. There are no supermen in his novels and periodically he kills of characters that he spent some time making you like. Much like le Carre novels the endings are not always happy.

Well I didn’t see that coming!
Another excellent book from master storyteller Mick Herron. The Dunstan brothers were fabulous bad guys, and you wouldn’t want to get on the wrong side of Win either!
Relieved that there’s one more Zoe Boehm book to read but I know I’m going to be gutted once I’ve read it because there’ll be no more (yet) to enjoy.

This book throws a huge wallop at the end. I love the characters, especially Zoe, of course, but also Tim and Win. Zoe always seems to start with a small job and ends up in dangerous situations. She's bright and tough, and this book has meditations on death all through it. I really like this early series from Herron.

Zoe Boehm is an effective and industrious PI in Oxford in need of work, and she certainly gets her work cut out for her in this case. Mick Herron is so good at crafting clever crime mysteries with twists, and this book is no exception. The ending caught me by surprise!

A slow start, and as the title suggests, a bit focussed on death. But it picks up admirably, with the sort of humour you'll appreciate if you like Carl Hiaasen or Christopher Brookmyre, and with many twists and turns.

This was my first meeting with Zoe Boehm, PI. Mick Herron writes very well but the characters in this book are not as fascinating as those in his Slough House series and Zoe, while physically intrepid, is no V.I. Warshawski. The plot seemed a bit clunky, there were some coincidences that stretched the reader's belief considerably and the final plot twist had a certain inevitability. If it hadn't been partly set in the suburb where I live, I might not have read to the end.
