Bookish
London, 1946 is the dynamic, dangerous and chaotic setting for this stylish new detective drama, with the eccentric Gabriel Book at the very heart of the story: a self-appointed consultant detective to the local police. The thousands of books that line the shelves of his shop provide him with all the knowledge he needs.
Book has gathered around him a host of lovable, damaged misfits whom he informally protects, cajoles, and mentors. His wife Trottie runs the wallpaper shop next door. She's a charismatic adventuress whom Book loves deeply but not physically, for they are in a 'lavender' marriage to help conceal Book's sexual orientation in a time when it was illegal to be gay.
Bookish marries post-war nostalgia with the reckless and life-affirming atmosphere of the times, creating a fast-paced and stylish detective drama.
