The ‘case-of-the-week’ comedy-drama also stars Anna Maxwell Martin.

Reclusive puzzle-setter John ‘Ludwig’ Taylor (David Mitchell) sees his life of solitude turned upside down when his identical twin brother, James, disappears without a trace. In a quest to track James down, Ludwig assumes his brother’s identity, but by taking over every aspect of James’s life, Ludwig is forced to confront his own. Unlike Ludwig, James is no hermit; he's a family man and a highly respected DCI within Cambridge's busy Major Investigations Team.

These are big shoes to fill for anyone, but for Ludwig playing dad to a ready-made family proves every bit as challenging as tackling the grisliest of crime scenes. However, Ludwig does have one big advantage – his ability to see the world in puzzle form. John may be a master of all things cryptic, but can he crack the biggest puzzle of his life?

Joining David Mitchell in the ‘case-of-the-week’ series is double BAFTA TV Award-winner Anna Maxwell Martin (Motherland, Line of Duty), as Lucy Betts-Taylor, John’s sister-in-law and wife of his missing brother James.

Also in the cast as series regulars are Dipo Ola (Landscapers, We Hunt Together) as DI Russell Carter, Gerran Howell (Catch-22, Suspicion) as DC Simon Evans, Izuka Hoyle (Boiling Point, Big Boys) as DS Alice Finch, Dylan Hughes (Malory Towers, Maternal) as Henry Betts-Taylor, Dorothy Atkinson (Mum, The Gold) as DCS Carol Shaw, Sophie Willan (Alma’s Not Normal, Time) as Holly Pinder, and Ralph Ineson (The Witch, Chernobyl) as Chief Constable Ziegler.

Guest stars in the series include national treasures Derek Jacobi and Felicity Kendal, Rose Ayling-Ellis, Karl Pilkington, Allan Mustafa (People Just Do Nothing, Peacock), Paul Chahidi (This Country), and Hammed Animashaun (Black Ops).
