"... All three films in
Agatha Christie's The Queen of Crime Collection are of high quality in costume, setting (London and Wales), and set design. The acting, of course, is topnotch across the board. Christie was fond of madcap amateur sleuths who have names like Bundle and friends called Badger and Pongo, and these films capture that period of British upper class bonhomie — with just an appropriate dash of brutal crime to keep the locals entertained. And these films should keep Christie and British mystery fans entertained, too."
Cheryl Campbell as Bundle and Christopher Scoular as Bill in The Seven Dials Mystery
