London, 1855. In the grey mist of early morning a body is dumped on the shore of the Thames. The city is soon alive with talk of a foreign killer and his accomplice: a young widow, Branna 'Birdie' Quinn. Sleeplessness led her to the river that morning, but she's no murderess. To clear her name, she must retrace the dead man's footsteps, a dangerous journey, but one she must make in order to save her life. Reads like a classic 19th century mystery.
