The season began airing on October 28, 2019 with the Halloween special Agatha Raisin & the Haunted House on Acorn TV. The remaining three feature-length episodes began airing weekly from February 10, 2020.
As a former high-powered London PR executive who retired early to a small, picturesque village in the Cotswolds (as beautiful as “chocolate-box England,” as Jensen describes it), Agatha had found a second calling as the sassy amateur detective investigating mischief, mayhem, and murder. She has resorted to unorthodox and amusing methods to help solve crimes in her newly-adopted deceptively devious town - Agatha Raisin has stayed all night in haunted houses, pretended to work on reality TV shows, donned flattering disguises and much more. She has also found herself topping a list of suspects and has had to race to prove her innocence.
In series 3 of this contemporary mystery, Agatha is now an official private investigator and operates her first detective agency, where pressures are high to keep new business flowing. In addition, she’s now living with on/off again beau and British history author, James Lacy (Jamie Glover, Waterloo Road).
Returning actors in AGATHA RAISIN Series 3 include eager Detective Constable Bill Wong (Matt McCooey, Skins); Agatha’s former PR assistant, Roy (Mathew Horne, Gavin and Stacey, Drunk History UK); the charming Sir Charles Fraith (Jason Merrells, Emmerdale, Waterloo Road), her friend, Sarah (Lucy Liemann, Rev), and Agatha’s new assistant, Toni (Jodie Tyack, Noughts & Crosses).
