LINDA MORGAN (Maimie McCoy)
Jilted bride Linda has a troubled past, so she's distraught when she's robbed of her happily ever after...
McCoy has popped up in Doctors, Raising The Dead, Desperate Romantics and Oxford based crime drama Endeavour, but before she came to Cambridge for Grantchester she was probably best known as The Musketeers’ Milady de Winter.
KITTY (Faith Alabi)
The seemingly shy and polite Kitty isn't as quiet as she'd have Sidney and Geordie believe...
If you’re a fan of Drifters, Agatha Raisin or Chewing Gum you may have spotted Alabi on your TV screen before now.
LARRY SIMPKINS (Terence Maynard)
Club owner Larry is a murky character - but is he capable of murder? That's what Sidney and Geordie need to work out.
Yes, that is Coronation Street’s Tony you see before you. Maynard is a veteran of the small screen with roles in everything from Dream Team and Doctors to Waking The Dead, Judge John Deed, Holby City, Young Dracula, Merlin, Public Enemies and Spy to name but a few. You may also have spotted him in cinemas in films like Chasing Liberty, Reign of Fire and Edge of Tomorrow too.
Felix Davis - Enzo Cilenti
The angry son of the murdered man doesn't think his father should have ever considered marrying his bride...
If you're a fan of Game of Thrones or Jonathan Strange and Mr Norrell you may well have spotted Cilenti on your TV screen before. He popped up on cinema screens in Bridget Jones's Baby earlier this year, playing Italian restaurant gem Gianni. You might also have spotted him in ITV's Jekyll & Hyde, historical drama Rome and Prisoners' Wives.
