Crime drama series written by and starring Mark Gatiss, which debuted on U&Alibi in 2025.
The series centres around the erudite and unconventional bookshop owner Gabriel Book (played by Gatiss) who is an amateur sleuth in his spare time. Set in London in 1946, Gabriel Book uses the thousands of books that line his shelves to help him solve even the most puzzling of crimes. Polly Walker plays his colourful wife Trottie. The couple are in a 'lavender' marriage in order to conceal Book’s sexual orientation in a time when it was illegal to be gay.
Tom Forbes guest stars in the first two episodes as "local spiv" Micky Hall.
