When Isabelle McLaren is given the devastating news that her ten-year old son, Thomas, has only months to live, she decides to take him to St Andrews to see Hamish McHamish, the town's famous cat who Thomas believes can cure him, if only he gets to stroke him.

But Hamish is missing, and when Thomas' health takes a sudden turn for the worse, Isabelle asks DCI Andy Gilchrist for help - find Hamish, and give her son his final wish. But in the season of goodwill to all men, will it take a cat to prove that miracles can still happen?

Praise for T.F. Muir:

'Rebus did it for Edinburgh. Laidlaw did it for Glasgow. Gilchrist might just be the bloke to put St Andrews on the crime fiction map.' Daily Record

'A truly gripping read, with all the makings of a classic series.' Mick Herron

'Gripping and grisly, with plenty of twists and turns that race along with black humour.' Craig Robertson

'Gilchrist is intriguing, bleak and vulnerable... if I were living in St Andrews I'd sleep with the lights on.' Anna Smith
