The Man Who Died

The Man Who Died functions as a darkly comic riff on the DOA narrative. A guy has been poisoned, and before he dies he needs to find out who did it. Add in the intricate details of the mushroom industry, poor eating habits, infidelity, and a missing samurai sword, and you've got yourself a stew!
Be warned, this book is absolutely disgusting. Its vision of the human body is of a fleshy tube covered in fluid-spewing orifices. Fair enough I suppose.
The best comparison in terms of style and tone is Dave Barry's novels from the late 90s and early 00s, Big Trouble and Tricky Business. Spicy, gross, comic misadventures packed with authorial voice. Definitely not for everyone, but some will get a real kick out of this one.
