In a Veil of Mist is based on the true life but little-known event of Operation Cauldron.
In 1952, during the Cold War, germ warfare experiments were taking place on a ship off the coast of the Isle of Lewis.
The book delves into the lives of two locals who begin to suspect something is amiss, Jessie and Duncan, and a lab technician who is working on the boat.
Murray skilfully constructs characters that feel inherently human and relatable, while beautifully depicting life in the Outer Hebrides.
A gripping, intelligent and often humorous read.
In a Veil of Mist, by Donald S. Murray, published by Saraband, £9.99.
