BBC iPlayer will premiere the second series of Ludwig on 20 August. The production, handled by Big Talk Studios, returns with David Mitchell reprising his role as John Taylor. In the new episodes, the character operates as a crime scene consultant for the Cambridge Police Authority, working with DCI Russell Carter, played by Dipo Ola, to investigate impossible crimes.
The plot continues the search for John's missing identical twin brother. Anna Maxwell Martin returns as Lucy, the sister in law of the lead character. The narrative involves the discovery of evidence boxes and a sequence of murders. The series introduces Sian Clifford as Joanne Kemper, the MP for Cambridge. The character of Kemper has connections to senior members of the police force and becomes a focal point for the inquiries conducted by John and Lucy.
The cast includes Mark Bonnar alongside the returning leads. The second series focuses on the professional relationship between the consultant and the police authority while maintaining the central mystery of the missing sibling. The production utilizes the Cambridge setting for the procedural elements of the script.
The first series established the premise of a puzzle setter assuming his brother's identity to solve a disappearance. The second series shifts the character's role to an official consultancy capacity within the police force. Ludwig is a co production between the BBC and Big Talk Studios.
