What is Bookish season 2 about?

Returning for another round of twisty mysteries, the second season follows Book as he’s asked to help solve a mysterious case involving a medium, Harold Sneed (Jason Watkins).

The synopsis reads: “Off Savile Row, Inspector Bliss (Elliot Levey) asks Book to help in a puzzling murder at a gentleman’s outfitters – the elderly tailor Maxie Kleinmann (Allan Corduner) is keen to confess to the murder, but the evidence doesn’t quite stack up and points to something much more complex and sinister.

“Meanwhile, Book and Jack Blunt are sent to the seemingly charming German village of Würl by the mysterious ‘E’ (Simon Callow) to thwart a thieving Duchess (Miranda Richardson) at Christmas time.

“However, festivities take a deadly turn when Book and Jack uncover secrets of their own, past and present, in an ominous castle brimming with plausible murder suspects.

“Book’s close association to the police continues to be not without its personal dangers and his lavender marriage with childhood best friend Trottie (Polly Walker), is threatened by debonair Colonel Winters (Rupert Graves).

“Marrying post-war nostalgia with the reckless and life affirming atmosphere of the times, Bookish is a stylish period detective drama with a difference.”
