As summer sets in, BritBox reprises its annual celebration of crimes and capers: Mystery Month. For fans of British period dramas, we found two offerings that are new to BritBox in July in the US and Canada.

One is a documentary where you can follow “chatty man” Alan Carr as he explores the world of the Queen of Crime in “Alan Carr’s Adventures with Agatha Christie,” and the second is a classic dramatic series featuring adaptations of mystery stories written by Sir Arthur Conan Doyle’s contemporary rivals.

New For Period Drama Fans on BritBox in July

Alan Carr’s Adventures with Agatha Christie (2022)

In this documentary, Alan Carr (Alan Carr: Chatty Man), comedian, TV personality and lifelong Agatha Christie fanboy, is going on a very personal adventure in search of the quintessentially British places that inspired his literary heroine. From the quaint villages of Miss Marple to the metropolitan Art Deco elegance of Poirot, this funny, fact-filled travelog is a glorious romp through Britain’s most beautiful landscapes, celebrating the woman who immortalized them in her writing and offering a fresh new perspective on her life and work.
