The Missing Link(1995)
(The first book in the Gil Yates Private Investigator series)
A novel by Alistair Boyle
It was crazy for introverted Malvin the palm grower to impersonate a private investigator.

The game quickly turns deadly with each unburied secret, until Malvin's own life hangs by a thread.
