The Detective

Rate this book
For 150 years, women have been going missing.

And all of the investigators who went in search of them - from 1877 to the present day - have disappeared, too.

Now Sam Speedman, a most unique private detective, is on the case.

Brilliant, direct and disarming, Sam is ... different. He's not your average private detective. But then again, this isn't your average case.

For not even he will be prepared for what he will find.

Set in the darkest corners of the American South, tapping into hot-button issues that simmer beneath the surface of the modern United States, this is Matthew Reilly writing faster and bolder than ever before, bringing you a detective thriller like no other.

Matthew Reilly

Born in Sydney in 1974, Matthew Reilly was not always a big fan of reading. It was only after he read To Kill A Mockingbird and Lord of the Flies in Year 10 that he realised reading could transport you to another world. Following this revelation, Matthew soon began creating stories of his own and set about writing his first novel, Contest, at the age of 19 while still at university studying law.

Following rejections from all the major publishers, Matthew self-published Contest in 1996, printing 1000 copies. He produced a big-budget-looking novel which he sold into bookshops throughout Sydney, one shop at a time.

In January 1997, a Commissioning Editor for Pan Macmillan Australia walked into Angus & Robertson's Pitt Street Mall store and bought a copy of Contest. The editor tracked Matthew down through his contact details in the front of the book. Interestingly, those original self-published editions of Contest have now become much sought after collectors' items. One recently sold on eBay for $1200!

Matthew Reilly is now the internationally bestselling author of the Scarecrow novels: Ice Station, Area 7, Scarecrow, Scarecrow and the Army of Thieves and the novella Hell Island; the Jack West novels: Seven Ancient Wonders, The Six Sacred Stones, The Five Greatest Warriors, The Four Legendary Kingdoms, and The Three Secret Cities; and the standalone novels Contest, Temple, Hover Car Racer, The Tournament, Troll Mountain, The Great Zoo of China and The Secret Runners of New York.

His books are published in over 20 languages with worldwide sales of over 7 million copies.

Since Seven Ancient Wonders in 2005, Matthew's novels have been the biggest selling new fiction title released in Australia for that year.

Matthew has also written several short stories, including Roger Ascham and the King's Lost Girl, a special free prequel to The Tournament which is available online. Other short stories include Time Tours, The Mine and the hyper-adrenalised romp, Altitude Rush.

He owns and drives a DeLorean DMC-12, the car made famous in the Back to the Future movies. He also has a life-sized Han Solo in carbonite hanging on the wall of his office! When not writing or penning a film script, Matthew can be found on the golf course.

Matthew Reilly is currently living in Los Angeles.

The Detective by Matthew Reilly is a mystery/thriller that starts off quirky in a great way and quickly escalates to an exceptional read! I’ve just found my new favourite hero in Sam Speedman who is one of the most interesting and authentic men I have met in a book. This story definitely packs a punch, it’s high-octane paced and I ate it up!

Sam Speedman is the ultimate PI you would want on your case, he is on the autism spectrum and whip smart. The plot delves into some dark and sinister themes but ones relevant to America’s history and the present.

Women have been going missing and the investigators in search of them also have disappeared! There’s a link that spans 150 years! The villains are heinous and what they get up to is utterly unimaginable.

The Detective is a witty, action packed, thrilling, violent and bold tale that’s set in modern day America. The maps, charts and drawings throughout the book are a great inclusion.

I love a book I can read super fast with short snappy chapters and I hope to see another Sam Speakman adventure in the near future. Spoil yourself and grab a copy you won’t regret it!

Have been sitting on this one for a few days because I'm not entirely sure how to put together all my thoughts about it...

I did the calculations whilst reading and discovered that I've been reading Matthew Reilly books for about half my life now (crazy), so there's a sense of comfort in coming back to the familiarity of his writing style; the fast-paced action, the side stories that always come back into play by the end of the book, the sentences that are followed by a shorter sentence on a new line with an italicised ending when something hectic happens like the protagonist jumping into a volcano or off a moving vehicle.

As always, this one was undeniably gripping, and very easy to sit and read almost cover to cover in one sitting, and that's far from my problem with it; I think where I feel a little unease this time around is with certain elements of the story and, maybe, who's telling it?

Whilst a detective thriller, this is ultimately a story about the deeply racist parts of the American South and, at its core, both historical and modern slavery. It's obviously all incredibly important- and relevant- stories, but the ways that parts of it were told just made me feel a little funny, knowing that it had been written by a white Australian man? To some extent, I can't quite place my finger on it, but it just made a little uneasy. For example, there's a scene where

Anyway... don't think I'll pop a rating on this one. Parts of it that I really enjoyed and was swept away in during the classic Matthew-Reilly-action-adventure of it all, but other parts that just felt strange to me, and I'm not really sure how to (or if I even want to try and) divorce those two different opinions/ reactions. Keen to hear what other people think once it's out!

It has been awhile since ai have read a Matthew Reilly novel and I devoured The Detective. Just brilliant.

I loved Sam Speedman, detective with a brilliant mind and a different way of looking at things and finding patterns. He sees what the others have been missing, and he is not afraid to get involved. I really enjoyed learning about him and his life, I hope we get more books with Sam.

This book has some pretty dark themes. It is the usual fast paced page turner that you expect from Matthew Reilly. A story of good vs evil, of mystery and tragedy. A story seeped in history and the errors of the past. Sam finds that not only has his client daughter gone missing, but that women’s have been going missing for 150 years in similar circumstances, and that their investigators have also disappeared. Using his incredible talent for patterns and not believing in coincidences, Sam is a man on a mission.

A very clever and powerful story, emotional and compelling. Matthew Reilly has done it again.

Thank you so much to Macmillan Australia for sending me a copy to read. Now my husband can read it 😅

Както и в други свои книги, авторът ни поднася една шеметна приключенска, криминална и адреналинова история.
Действието се развива предимно в Луизиана, един погълнат от тресавища и с труднодостъпни места щат. В Луизиана можеш да скриеш много неща. Мощни урагани унищожават периодично територията. Урагани, които погребват или разкриват тайни.
Намерено е мъртво бебе. Бебе, свързано със стар случай на Сам, частен детектив. Сам е необичаен герой с интересни способности. Навързва престъпленията и стига до истината. В името на справедливостта той ще се изправи срещу мощни стари фамилии от Луизиана. Трудна битка, но са заложени човешки животи.
Действието на книгата е динамично, забързано, поглъща те и не можеш да спреш да четеш. Стилът на автора е кинематографичен, с кратки изречения. На страниците на книгата ви очакват още преследвания, стрелби и фрагментирани описания на американските щати и живота в тях. Илюстрациите в нея са много добро решение и ги има във всичките му книги. Допадна ми още как авторът водеше своя герой и навързваше нишките на разследването. Хитро и интересно.
Препоръчвам и винаги ще препоръчвам Матю Райли, когато искате да четете нещо динамично и приключенско. В някои от неговите книги има и свръхестествени елементи. Ще продължавам да търся и чета негови книги.

Buy it, read it in one sitting because any other way and the absolute exhilaration of this novel will not have your mind racing and this is a fast novel.
Only the third book of Matts, I met him at a conference and have sold his books for 17 odd years so yeah we on a first name basis like that, the other being Mr Einstein's Secretary and the third Cobalt Blue, and yep, he can turn a tale.
I was going to read the Seven Ancient Wonders series but the ending got spoiled at the conference so I have to wait for my memory to forget that before I pick it up.
So yeah buy it. Nice work Matt.

Would have been a higher rating except for the random need for the shower. Why did the “thanks for saving me from being raped sex” have to be included. Was not needed.

Really torn thinking about how I ended up finding this book overall.

Did I enjoy it? Yes

Did I finish it in just over 24 hours? Yes (normally a good sign that I loved a book)

Was I expecting a bit more from a Matthew Reilly book? Also, Yes

What I loved. I LOVED the protagonist Sam Speedman and the way he thought and interacted with other characters throughout the story. He reminded me a lot of myself (I’d like to think) - someone who always tries to be nice and has a very analytical brain - perfect for a detective.

However, I kept reading this book waiting for the big, quintessential Matthew Reilly Moment, yet I never got it.

Overall, while I thoroughly enjoyed it, it just felt like it was lacking a few elements to turn it from a great book into a jaw-dropping book.

I am keen to see what he does with Sam in the next one!

A tough one to review, I liked the pace and was never bored, but I think I enjoy the fantasy/adventure aspects of Reilly’s novels. I think the seriousness of the subject matter isn’t always aligned with the style.

I will never not say this when it comes to Matthew Reilly releasing a book and that fact is that I WILL ALWAYS BE SO EXCITED and IT WAS SO FUCKING GOOD. Now having read over twenty books from Matthew ALL OF THEM have been immaculate EVEN when they are so unique! And The Detective was NO DIFFERENT. It was as Matthew Reilly as it could get, and I COULD NOT. The fast-paced action, the plot twists, the way I could have finished this within the first day of getting it and the SITTING ON THE EDGE OF MY SEAT FOR ANSWERS GODDAMMIT.

I really, and when I say really, I mean REALLY liked Sam Speedman. He was witty, funny and just overall himself and I found myself having a good giggle at some parts. I also enjoyed the fact that he wasn’t the stereotypical “hero” as we’ve seen previously with Scarecrow or Jack West. He was just Sam and that’s all he needed to be. With even being Sam, it lead him to having some fun adventures with his partner-in-crime at the time, Audrey. *smirk*

Overall, I had a BLAST while reading this book, not to mention the aftermath of everything REALLY pulled my heartstrings. I ABSOLUTELY CANNOT WAIT to see more adventures of private detective Sam Speedman and his crew, as well as ANY other Matthew Reilly future releases!

Like every other Matthew Reilly book, it's fast paced and filled with excitement. This was a great read and very interesting story to tackle. The pre-chapter quotes really hammered home how this was still such a prevalent issue in the world we live.
The book seemed like a large read but I managed to smash it out in two days because of two reasons. The first, it was encapsulating and I couldn't put it down. The second, it was actually quite short. At 360 page I thought it might stretch out, but with a lot of empty space and pages throughout I found I was turning pages a lot. It was a great length for the detail that was delved into, but would have loved some more. Is there any chance of Sam returning for another case in the future?

Typical Matthew Reilly book with interesting characters, fast paced and with plenty of action. A real page turner. Almost a Jack Reacher type of storyline with a good versus evil plot. The first book in a long time that has been so engaging that I read it easily within a day. I think I may have enjoyed it all the more having had a small taste of the Louisiana swamps and could easily picture the trees hanging with Spanish moss, the airboats and the alligators.

As a long-time Matthew Reilly reader, I devoured The Detective in just three hours. It’s fast, cinematic, and full of that trademark Reilly momentum but what struck me most was how much his storytelling has matured.

Sam Speedman is a fantastic lead. Reilly captures his voice perfectly, Chandler-esque, yet still distinctly his own. The choice to write in first person isn’t peak Reilly for me; I’ve always loved how his third-person thrillers let the action, characters, and settings expand in vivid, immersive ways.

It’s thrilling to see an author known for high-octane adventure push into new creative territory while keeping the heart-racing energy fans love.

Not the conventional Matthew Reilly story but it kept me hooked all the same. Each page turn couldn't be the last unless something pesky like work required it to be.

Reilly's crime fiction detour never strays far from his conspiratorial action novel roots. With his signature lead-foot pace, he explores new characters and locales, while never quite reaching the scale or spectacle of his other books.

While a page-turning read with a pointed social commentary, Reilly's voice as a white Australian man providing cultural commentary on the lasting impacts of racism in the US South never quite escapes the uncanny valley.

This was so easy to read in one day . The Detective is what I expect from a Mathew Reilly hero . Sam Speedman is the ultimate detective without being cringeworthy. The book is full of action and explosions. I adore the maps and extra images to cement into your mind the vehicles used in the story. This is a brilliant investigation featuring an age old injustice and thought provoking mindset . I look forward to the next adventure for the new Detectives .

A brand new protagonist and unlikely hero, Sam Speedman, a thorough and brilliant PI, takes on a disturbing case. He see things others have missed and uncovers an unsettling conspiracy that threatens his life.
Witty, thrilling and violent - The Detective is all mystery and action!

Ok so over the last few years I’d liked Matthew Reilly’s books less and less…. But this was was pretty great.

At least as far as I remember this is the first first person one which I quite liked, and the story is pretty far from his others. It was also pretty fucked up, even for him, because for once it all felt at least vaguely possible. I’m saying that, man is he the antithesis of subtle. I get that the story is about modern slavery and he really wants to drive that point, but no one is looking out at a bunch of slaves and going “wow look at all these modern slaves”. And I swear Audrey is is just there to go “OMG this is all so horrible” half the time. And don’t get me started on what ever that love b-plot was between them. It made no sense and consisted of like 10 sentences all of which could (and should) have been removed.

There was a lot wrong with this book, as there seems to be with all of Matthew Reilly’s book. But they were wrong in a way that is so him and that I can’t help but kinda love. The plot is amazing even if the writing kind of isn’t. Solid 4/5

I started reading this book because me dog died and I needed a book I knew I would like.
Very satisfied. One of the best reads of the year- very bold statement it’s NOVEMBER. I am going to miss the feeling of reading this for the first time. It wasn’t like overly surprising- u could kinda pick the “murderer/how they did it” really early. But it wasn’t a straight line mission either.

I think Matty Riels is getting better at writing as he ages- maybe also the target audience is broadening to beyond Teenage Boys who Can’t Wait to Join Up.
Another classic MR move where the protagonist is MR himself, in another life, born in a different country, where he never got to love Natalie. Autistic Nerd solves Big Issues Well because of his nerd skills. (Still gets the girl). Keen for the sequel- promised 2026.

Phew. Now I can relax. And maybe have a rest and come down from a Matthew Reilly induced high.

The Detective introduces the world to a new super hero, Sam Speedman, a gawky, physically unimposing legend who also happens to be autistic and his awkwardness is harnessed by Matthew Reilly so that you can add honest, decent and downright loveable to Sam’s description.

The plot is as dark as anything Reilly has written but Sam just marches straight through and drags his small band of similarly likeable good guys with him.

As with everything Reilly writes, the highly improbable becomes the accepted reality and you find yourself smiling so often throughout the reading.

Above all, The Detective continues the Matthew Reilly trend of offering 24 carat entertainment and I love his work for that factor.

This took under 24-hours to read. This is a brilliant book & Sam is my new hero. This isn’t just a fast paced mystery/thriller but has very deep and dark themes, that are sadly still all too relevant today.

Another great read by Matthew Reilly. A slightly different take than his usual, basing it in modern-day America. It definitely feels like a bit of commentary on current events in some places...

I liked the character of Sam Speedman. A classic Reilly protagonist and yet unique in his own way. I did feel like the romance was a little forced and kinda unnecessary. Highly enjoyable still though!
