Stephen Mangan is Ed, leading a new life as a bike repair man in a village. And then we discover why in Marcy Kahan's smart, sharp, witty play. Twenty minutes in one day changed his old life utterly. He spotted a national treasure in the street, Pen Rhinehart (barrister, author, erstwhile circus clown) and called out to him. Pen was on a bike. Ed's cry made him wobble and fall under a lorry. No one saw. Ed ran away. Ren was taken to hospital by others. He's not dead. But Ed is being pursued by wildly assorted demons.

If you've ever seen one of your favourite celebrities in the street and felt compelled to let them know just how great you think you are, Marcy Kahan's comedy will have you thinking twice. Stephen Mangan is at his overwrought best as librarian Ed Hanson, who has two items on his to-do-list for the day: present a "vision statement" to keep his job, and propose to his girlfriend. Unfortunately, on the way to work he sees polymath national treasure Penhaligon Rhinehart cycling down his road and uncharacteristically proclaims Rhinehart's greatness - an act that has dire consequences. As much a fable about the truth behind the carefully constructed image of public figures as the consequences of our actions, the play is full of hilarious situations and witty lines.

PG Wodehouse's suave Psmith (Nick Caldecott) comes to the rescue of his old school friend, the solid Mike (Inam Mirza) when poor Mike's suddenly impoverished and so forced to leave university to take a humble post in the City. It's a good job, Psmith is working there too, for if ever a cove knew how to get round the Head of Post, even subdue the very bossy boss, it's Psmith. Simon Williams narrates. Marcy Kahan, an award-winning playwright clever enough to turn Noël Coward into a credible detective, has done the natty four-part adaptation.
