Murder in the Blood — Lesley Cookman

Libby Sarjeant and friends are taking a well-earned holiday at a village on the Turkish coast, looking forward to a peaceful and relaxing escape from it all. Despite their best intentions however, it seems that murder has even followed them there.

When out on a boat trip they discover a body, but for once it has nothing to do with them (they're on holiday in a foreign country, after all!). Then they discover the deceased was English - and so are the suspects.
