8September, 1939: As Britain readies for war, one woman must battle a ruthless killer. Inspector Betty Church--one of the few female officers on the force--has arrived from London to fill a vacancy at Sackwater police station. But Betty isn't new here. This is the place she grew up. The place she thought she'd left for good. After a slow start, Betty's called to the train station to investigate a stolen bench. But though there's no bench, there is a body. A smartly dressed man, murdered in broad daylight, with two distinctive puncture wounds in his throat. While the locals gossip about the Suffolk Vampire, Betty Church steels herself to hunt a dangerous killer.
