Death of a poison pen - M. C Beaton

A sudden outbreak of maliciousness strikes the town of Lochdubh in the form of a rash of poison pen letters. Things turn deadly when the local postmistress is found hanged in her room... with a vicious note beneath her dangling feet. Though his superiors call it suicide, PC Hamish Macbeth pronounces it murder. But Hamish is soon distracted by Jenny Ogilvie, a friend of his ex-fiancee, who arrives in Lochdubh to seduce him. And then he's ambushed by local reporter Elspeth Grant, who sets out to land the story - and Hamish - for herself.

Caught in the middle of this volatile case, Hamish faces dangerous romances... and a blackhearted culprit wielding a mighty - and lethal - pen.
