In a Dry Season is the 10th novel in Peter Robinson's Inspector Banks series, following on from Dead Right. During a blistering summer, drought has depleted Thornfield Reservoir, uncovering the remains of a small village called Hobb's End - hidden from view for over 40 years.
The first message sent to Tom Thorne's phone was just a picture - the blurred image of a man's face, but Thorne had seen enough dead bodies to know that the man was no longer alive. But who was he? Who sent the photograph? And why? While the technical experts attempt to trace the sender, Thorne searches the bulletins for a reported death that matches the photograph. Then another picture arrives.
