Good news for mystery fans! The new season of popular period mystery Grantchester will air in the U.S. this June. The drama’s third season will begin on Sunday, June 18 at 9pm. (So mark your calendars now!)

Stars James Norton and Robson Green will be back as the crime-solving duo of vicar Sidney Chambers and his partner Detective Inspector Geordie Keating. The drama is based on the “Grantchester Mysteries” books author James Runcie, and Season 3 will likely map to the third novel in the series, Sidney Chambers and the Problem of Evil.
