What to expect from Bookish season 2
Series one, which was hailed as “excellent” by viewers, introduced bookshop owner Gabriel Book, who helps the police solve “the strangest of crimes and the knottiest of murders”.
In season two, Book investigates the world of spiritualism when he’s asked to help solve the mysterious case involving medium Harold Sneed. The synopsis continues: “Off Savile Row, Bliss asks Book to help in a puzzling murder at a gentleman’s outfitters – the elderly tailor Maxie Kleinmann is keen to confess to the murder but the evidence doesn’t quite stack up and points to something much more complex and sinister. And Book and Jack are sent to the seemingly charming German village of Würl by the mysterious ‘E’ to thwart a thieving Duchess (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.”

The synopsis concludes: “Book’s close association to the police continues to be not without its personal dangers and his lavender marriage with childhood best friend Trottie, is threatened by debonair Colonel Winters. Marrying post-war nostalgia with the reckless and life-affirming atmosphere of the times, Bookish is a stylish period detective drama with a difference.”
All six episodes are available to stream via Sky, NOW and Virgin Media.
