A world renowned professor from the Highland's University has invented a prototype weather machine that can create sunny summers in the British Isles. Or make it rain in drought-stricken California. Or stop glacial melt in the Arctic. The technology is getting more than a lot of attention. In fact, it is beating all records for procuring grants from companies all over the world. But when the grant money starts to dry up for other programs, some of the other professors are not very happy. And when one of them meets with a violent death, Mick Malone and Jock McDuff are hired by Police Scotland to help solve the crime. Is international espionage behind the latest rash of murders in the Highlands? Or is it something much closer to home? And when love and loyalty are challenged, it threatens to drive a wedge between the two detectives. In this, the sixth Mick Malone Mystery, Mick and Jock begin a journey that will test their partnership to the core.
