Close Quarters (Rue Morgue Classic British Mysteries)

Although it was first published in 1947, Gilbert began this novel in the years immediately before World War II and didn't finish it until he returned from active duty. Set behind the walls of the residential Close of Melchester Cathedral, it's a classic British mystery in which a young Scotland Yard detective is asked to interrupt his holiday to find out if the accidental death of Canon Whyte was indeed an accident.
