A choice of evils Book

Retired professor Andrew Basnett just wants a few quiet days by the sea, so he goes to Gallmouth, where he and his late wife had vacationed. Much to his surprise, he finds that his nephew Peter, a science fiction writer, is there for the first Arts Festival. Through Peter, he reluctantly finds himself involved with some other festival partipants, including thorny, successful author Simon Amory. When widowed Amory's sister-in-law is found murdered--by Peter--Basnett becomes involved in the investigation since the officer in charge conveniently knows another police officer Basnett helped in the past.
