Henry Reymond Fitzwalter Keating, known informally as Harry, will probably be best remembered for creating Inspector Ghote of the Indian police, though more recently he had started a new series featuring Harriet Martens. He was also a fine critic and reviewed crime fiction for The Times for over 15 years, taking over from Julian Symons.
