This is another Sherlockian mystery from the inimitable author of A Taste for Honey, and Reply Paid. And once again the meticulous Mr. Mycroft plays the role of detective. The setting is simplicity itself. Here is a lovely arbor in a quiet Shropshire garden. There lies the body of a man killed by the thrust of a slender instrument identifiable as an antique hairpin. Was it really suicide, as Mr. Mycroft's colleague believes?
