Lord James Harrington and his wife, Beth are taking a well-earned holiday with Stephen and Anne in Polpennarth, Cornwall, where the Cornish Legends festival is taking place. James learns that, during the opening procession, a local fisherman vanished and, when further men disappear in broad daylight, he can't help but put his sleuthing hat on. The streets were crowded yet no witnesses have come forward. If they were kidnapped, why is there no ransom demand? What are the flashing lights off the coastline? Have the Cornish Legends really come to life? James delves into the mystery but his questions come at a price.
