Detective Inspector Michael Angel and his team are desperately searching for a wild cat on a killing spree in the South Yorkshire town of Bromersley. It appears that the cougar is under human control and is trained to kill to order. Retired schoolteacher and well-known cat enthusiast, Miss Ephemore Sharp, becomes the prime suspect, but Inspector Angel is unable to prove her guilt. Matters take a decisive turn when she is found in possession of the antique pot figure of a famous performing cat called 'Pascha'. Angel is greatly tested and the investigations become more mystifying and dangerous, as he races to find the explanation to stop more mayhem and murder. This is the 18th in the highly successful Inspector Angel series.
