In this, Ms. Allingham's last novel, the action revolves around Saltey, for centuries a hidey-hole for all manner of villains. Astonishingly, it is the early 1960s, and Saltey, like many English coastal towns, is being over-run by teenage gangs. But that's not why Albert Campion — now, astonishingly, in late middle-age — has persuaded Lugg to take up residence. His interest lies in part with the just-out-of-prison thief who has (in time-honored tradition) gone to ground in Saltey. But his most passionate interest is reserved for the curious, newly revived story of the Saltey Demon.

All books in the Albert Campion series are standalone titles and can be read in any order.
