Charters & Caldicott

Charters & Caldicott were originally two characters in the 1938 Hitchcock thriller "The Lady Vanishes". Writer Keith Waterhouse took them and turned the clock ahead to their retirement years and wrote six mystery plays about them. Charters was played by Robin Bailey (The Power Game, The Pallisers, I Didn't Know You Cared, Jane, Potter, Bleak House, Rumpole Of The Bailey) and Caldicott by Michael Aldridge (Sense And Sensibility, Fall Of Eagles, Love For Lydia, Tinker Tailor Soldier Spy, Love In A Cold Climate, Spyship, Last Of The Summer Wine, Stanley And The Women). Others actors appearing include Caroline Blakiston (The Mallens, Mr. Palfrey Of Westminster, Brass, Return Of The Jedi and was Lionel's ex-wife Margaret in one memorable episode of As Time Goes By), Tessa Peake-Jones (Pride And Prejudice, Up The Garden Path, So Haunt Me, and immortalized as Raquel in Only Fools And Horses), and Gerard Murphy. Charters & Caldicott was also featured on PBS' Mystery Theatre in the US. In fact, these are from tape recordings of those broadcasts.
