Enigma
There was a killer on the island

The police called the criminal Enigma because their only clue was a cryptic note indicating the killer's next destination. So Addie Cordero, psychologist and graphologist, was sent to isolated Galbraith Island to find out who had handwriting to match Enigma's. A party game left Addie with unsigned writing samples from twelve prime suspects, and one of them was Enigma's.

This was no time to trust her heart, but Addie couldn't resist Jason Farrell, a mystery man whose sensuality drew her to him despite her fear. She thought it would be easy to eliminate him as a suspect, but as she crossed names off her list one by one, his remained. Could she take the chance that his charming facade hid a cunning killer?
