Catchee Monkey: A Rex & Eddie Mystery (Rex & Eddie Mysteries Book 1)

Two Detectives. One Murder. No Clue.
The first in the Rex & Eddie Mysteries series, Catchee Monkey is a comedy-mystery - or daft noir - that lovingly mashes the pulp detective novel with a British twist.
When Eddie is persuaded to start a detective agency with his friend Rex, he hopes to set up a respectable business, while Rex sees it as a chance to play out his noir fantasies.
The inexperienced sleuths stumble upon a murder mystery that puts them head-to-head with gangsters, assassins, and corrupt coppers. Outnumbered, outgunned and outwitted, they have to solve their case before it kills them, or before they end up killing each other.
