Edinburgh, 1936. People are disappearing. The police are clueless. Can Finlay MacBeth track down the perpetrator before someone else goes missing?

Haunted by his recent past, Professor Finlay MacBeth returns to his home town to take up a new post at the university. Within hours, his reputation for solving the occasional murder prompts the police to ask for his help. Four men—seemingly unconnected—have vanished into thin air. MacBeth must find whatever it is that links the men before the kidnapper strikes again.

But the police aren't the only ones interested in MacBeth's activities, and the amateur sleuth soon discovers that finding the missing men is the least of his problems...
