When Liverpool solicitor Harry Devlin watches fire destroy the studio of his client, tattooist Finbar Rogan, he suspects it is no accident. And when a bomb is planted under Finbar's car, Harry is left in no doubt. Someone hates Finbar enough to want him dead.

Meanwhile, another client is provoking Devlin's curiosity. Why should Rosemary Graham-Brown and her husband suddenly be so anxious to leave their luxurious home and emigrate to Spain? After a brutal murder occurs, the two puzzles become interlinked. Piecing the clues together, Harry finally comes face to face with the shocking truth at a fatal confrontation on a foggy Hallowe'en.
