Mamur Zapt and the Night of the Dog by Michael Pearce
Disturbances between Copts and Moslems in Cairo in 1909 means trouble for Mamur Zapt, British head of the Secret Police. Jane Postlethwaite, niece of a visiting MP, means trouble of a different kind. Captain Owen is fortunately - and delightfully - equal to both. The author has written Mamur Zapt and the Return of the Carpet.
