"Highly intelligent and educated half-wit" Julia goes on a holiday to Venice where she's accused of murder. Her friends back home in London, mainly barristers, take it upon themselves to solve the crime and prove Julia's innocence. It is narrated by Hilary Tamar, Oxford don of unspecified gender, and told largely although not exclusively through Julia's letters to her friends and their commentary on such. Very witty and funny, full of intelligent and only slightly eccentric people, the series about Professor Tamar is excellent
