Walking to the shops one day, Eugene Wren finds an envelope bulging with cash, in this 2008 novel by the late Ruth Rendell, author of the Inspector Wexford mysteries. A man plagued by a shameful addiction, Wren hatches a plan to find the money's rightful owner by printing a notice and posting it around Portobello Road. This ill-conceived act creates a chain of events that links Wren to other Londoners, each afflicted with his or her own obsessions and despairs. As these volatile individuals come into Wren's life—and the life of his trusting fiancée—the consequences will change them all.
