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.
