A Whiff of Cyanide (Hampstead Murders, 3)

The third volume of the Hampstead Murders series sees the team become involved with a suspicious death at a crime writers' convention. Is this the result of a bitterly contested election for the Chair of the Crime Writers' Association, or are even darker forces at work? Peter Collins, who is attending the convention as the author of a new book on poisoning in Golden Age fiction, worries that the key clue to unlock this puzzle may be buried within his own memories. A character called Miss Marple offers her advice, but how should the police receive this? Meanwhile an act of sudden, shocking violence and a dramatic revelation threaten tragic consequences.
