Joan Collins signs up for 'Marple'

Rex Features

Joan Collins is to star in the next hour-long episode of Miss Marple.

The 75-year-old will play Ruth Van Rydock alongside Julia McKenzie, who took on the role of the famous detective last year.

Collins's appearance in They Do It With Mirrors is reportedly a dream come true.

"It has always been Joan's dream to star in Miss Marple... She is one of the main characters and has some great scenes," a source is quoted as saying.
