Mark Gatiss returns as Gabriel Book for Bookish Season 2, bringing six new mysteries set in postwar London. The antiquarian bookseller once again assists the police through his extensive knowledge of literature and his ability to notice details others might overlook, making books and literary clues an important part of each investigation.
The new season continues the series’ blend of period atmosphere, unusual characters, literary puzzles and traditional crime mysteries. Among the cases ahead are a disturbing spiritualism investigation involving medium Harold Sneed, a murder at a Savile Row gentlemen’s clothing shop and a mystery that takes Gabriel and Jack to the German village of Würl.
Polly Walker, Connor Finch, Elliot Levey and Buket Kömür also return, keeping the central ensemble together for the new collection of cases. With six mysteries offering very different settings and circumstances, Gabriel Book once again has plenty of unusual problems to solve. Which of the new mysteries sounds most exciting to you?
