HOW DO YOU SOLVE A MURDER, WHEN ALL YOU HAVE ARE QUESTIONS?

When a prominent MSP goes missing, DSI William Lorimer wastes no time in investigating. Robert Truesdale was fronting the controversial campaign to legalise drugs in Scotland, and his enemies were numerous. With every passing day, the chances of finding him alive grow slimmer.

Then the worst happens. A car bomb explodes in a nearby village, and the blackened body pulled from the wreckage appears to be Truesdale's. Yet there are details that don't add up and soon Lorimer is questioning whether the victim was all he claimed to be.

Lorimer calls on the assistance of his friend, PC Daniel Kohi, who has infiltrated a local gang as part of a police initiative to crack down on drug-related crime in Glasgow. As their investigation draws them into the dark heart of Glasgow's criminal underworld, Lorimer and Kohi discover that danger is everywhere and nobody is as they seem.
