Actor-manager Abercrombie Lewker and his charming wife Georgina are vacationing in a remote corner of Cumberland when Lewker, who rather misses his spying adventures in World War II, is called on to help find a missing climber. Something about the circumstances--and local reports of a similar incident in the recent past--make Lewker wonder what's amiss. Both victims had been staying in the local hostel, so Lewker spends several nights there too, eventually reaching a shocking conclusion. (Although I did see it coming!) Not as much about rock climbing as I've read in some other books with this kind of setting.
