Who else is in Ludwig series 2 and what of the storyline

There’s a lot to unpack from the latest press release:

Picking up from the end of series one, master puzzle-setter John ‘Ludwig’ Taylor (David Mitchell) is now a Crime Scene Consultant, working alongside DCI Russell Carter (Dipo Ola), on ‘impossible’ crimes for the Cambridge Police Authority. No longer having to masquerade as his brother, he’s openly more ‘Ludwig’ than ever — brilliant at solving puzzles but hopeless at everything else.

But John’s identical twin brother, James, is still missing, and now that he’s an official employee of the station, John is forbidden from using any police resources to look for his brother or uncover exactly what he was investigating.

Of course, John won’t stop and neither will Lucy (Anna Maxwell Martin), John’s sister-in-law and wife of his missing brother James — a puzzle needs solving and a husband and father needs bringing home. One masquerade may have ended, but a new one has just begun.
