Katie, 30, whose ghost-written literary career and other business projects have turned her into a multi-millionaire, says she and husband Peter Andre regularly shun glitzy parties for a night in with a murder mystery box set.

“We love watching shows like Trial And Retribution or Morse.

I’ve always loved crime stories like Miss Marple and whodunnits because they keep you guessing until the last minute. I’d love to write one myself.”

Katie, whose latest novel is Angel Uncovered, adds: “Everyone thinks me and Pete are always out partying but we’ve got kids and we work very hard so it’s just not like that any more. Besides, I’m a lightweight these days.” Surely not.
