The crimes begin in a bizarre fashion. First, a busload of tipsy sightseers braving London's terror tour disappears on notorious "Murder Street."

Worse, the young son of a visiting American actress disappears in the wake of a series of abductions.

But nothing is as it seems, not even the people, nor the events on Murder Street, which Coffin fears may continue to live up to its bloody history.
