Synopsis: It's Christmas in Aberystwyth and a man wearing a red-and-white robe is found brutally murdered in a Chinatown alley. A single word is scrawled in his blood on the pavement: 'Hoffmann'. But who is Hoffmann? This time, Aberystwyth's celebrated crime-fighter, Louie Knight, finds himself caught up in a brilliant pastiche of a cold-war spy thriller. From Patagonia to Aberystwyth, Louie trails a legendary stolen document said to contain an astonishing revelation about the ultimate fate of Butch Cassidy and the Sundance Kid, but he's not the only one who wants it. A bewildering array of silver-haired spies has descended on Aberystwyth, all lured out of retirement by one tantalising rumour: Hoffmann has come in from the Cold. Louie Knight, who still hasn't wrapped up his presents, just wishes he could have waited until after the holiday.
