The death of a young artist leaves Gently desperately piecing together the portrait of a murderer. When artist Shirley Johnson is murdered and her body dumped outside a provincial police headquarters, Gently is despatched from London to Northshire to take over the investigation. The prime suspect appears to be the woman's husband, a former bomber pilot with a guilty secret, but the other members of the woman's art group also have strong views about her and her controversial final painting - Dark Destroyer. With so many suspects to consider, Gently must get to the bottom of the mystery before the murderer manages to slip through his fingers.
