Episode 3
A quiet day in Cambridge is thrown into disarray as Leonard and his new lady friend Hilary are witness to an armed robbery at the post office. With a gun pointed in his face, Leonard attempts to talk down the masked culprit and receives a strike to the head for his bravery.
Back from a morning run, Sidney is joined by former flame Amanda at the vicarage. Having agreed not to take their relationship forward, they exchange pleasantries but keep their distance. As Amanda leaves, Mrs Maguire encourages Sidney to stay strong. Sidney’s longing for Amanda only worsens when he later sees her with estranged husband, Guy.  Could Amanda be contemplating a return to her old life?
As Leonard is hailed a hero, Sidney and Geordie investigate the post office robbery and it soon becomes clear, this is the first of many.  As the robberies become more violent, Sidney and Geordie must work quickly to unmask Cambridgeshire’s very own Bonnie and Clyde.
Series overview
James Norton and Robson Green return as the unlikely 1950s crime fighting duo, Vicar Sidney Chambers and Police Inspector Geordie Keating, in the third series of Grantchester, produced by Kudos.  The six-part series is based on The Grantchester Mysteries by James Runcie. 
Tessa Peake-Jones is back as Sidney’s sharp tongued housekeeper Mrs Maguire who keeps the vicar in check; Morven Christie reprises her role as Sidney’s forbidden lover Amanda; Al Weaver returns as the timid curate Leonard Finch; Kacey Ainsworth is back as Geordie’s long suffering wife Cathy, Lorne MacFadyen puts his police helmet back on to play DC Phil Wilkinson and Seline Hizli returns as the feisty police secretary Margaret. And of course it wouldn’t be Grantchester without the return of the gorgeous black Labrador Dickens.
