Diary: Claydon turns his talents to the world of showbiz

For most admen, "gardening leave" is that once-in-a-blue-moon licence to kickback and relive your student life again.

So when Jon Claydon, the chairman of Work Club, quit Claydon Heeley last year, he was expected to take a deserved rest. But rather than succumb to a life of lie-ins, lunches and long afternoons, he revisited an old pet project.

It came in the form of a stage thriller, called Haunted, which he began writing in the mid-naughties with his freelance planning pal Tim Lawler. In a flurry of activity, the pair checked in to a motorway hotel and put the final touches to the play.

Now, in a miraculous bit of beginner's luck, the work has caught the interest of agents, actors and producers, and makes its West End debut next month. Stars include EastEnders' Jessie Wallace and Casualty's Sue Devaney.

First it was cars, now it's West End theatre. Diary can't wait to see what's next on Claydon's investment portfolio.
