There has never been a murder on Alderney. It's a tiny island, just three miles long and a mile and a half wide. The perfect location for a brand-new literary festival. Private Investigator Daniel Hawthorne has been invited to talk about his new book. The writer, Anthony Horowitz, travels with him.
Very soon they discover that all is not as it should be. Alderney is in turmoil over a planned power line that will cut through it, desecrating a war cemetery and turning neighbour against neighbour.
