About the Author

“THAT’S HIM!” GOWER YELLED above the sound of the traffic. Pitt turned on his heel just in time to see a figure dart between the rear end of a hansom and the oncoming horses of a brewer’s dray. Gower disappeared after him, missing a trampling by no more than inches.

Pitt plunged into the street, swerving to avoid a brougham and stopping abruptly to let another hansom pass. By the time he reached the far pavement Gower was twenty yards ahead and Pitt could make out only his flying hair. The man he was pursuing was out of sight. Weaving between clerks in pinstripes, leisurely strollers, and the occasional early woman shopper with her long skirts getting in the way, Pitt closed the gap until he was less than a dozen yards behind Gower. He caught a glimpse of the man ahead: bright ginger hair and a green jacket. Then he was gone, and Gower turned, his right hand raised for a moment in signal, before disappearing into an alley.
