A respected businessman is stabbed in his own home. His wife is found dead in the garage in what appears to be a murder-suicide. But as Police Scotland start to review the evidence in this case, nothing is adding up and D.S. Galen Cullen calls on her friend and colleague, Mick Malone for help. Mick and Galen soon find out that even a small village like Glengarron holds big secrets. But the two must travel over four hundred miles away, over land and sea, to unravel this mystery. And while Mick is trying to catch a devious killer, his partner, Jock, is trying to help the British government find out who is trying to steal the plans for Wanda, the infamous weather machine invented by Glengarron's own Professor Dawes. The seventh Mick Malone Mystery takes Mick and Galen to the Isle of Bummle where the island's elders are keeping a thirty year secret. And Jock has been keeping a secret of his own.
