ACTOR Christopher Biggins and socialite Nancy Dell?Olio attended a murder mystery evening in aid of the Kenton Theatre in Henley.
About 90 people attended the event at the Fawley Hill home Sir William and Lady McAlpine on Saturday.
The event was set in the Victorian era, so the guests dressed in black tie and ball gowns. They gathered at the station in the grounds, where they were met by an actor playing Dr John Watson.
He told them that Sherlock Holmes was away on business in Switzerland for ?something to do with FIFA?.
However, once the first guest had been ?killed?, the train conductor revealed himself to be Holmes by putting on his trademark deerstalker hat and declaring ?the game?s afoot?.
The guests then had dinner on the terrace and were interviewed by Holmes before the killer was finally unveiled as the porter.
After dinner Biggins hosted a silent auction with lots including a ride in an aeroplane with Bremont watches co-founder Giles Bremont and a trip to Paris to see the musical Cats.
Ed Simons, chairman of the Kenton trustees, said: ?It was a brilliant evening with some fantastic prizes. Everyone was very enormously generous.
Lady McAlpine said: ?It was a brilliant night, very fun and hilarious throughout.?
The evening was raising money for Kenton for Keeps and the refurbishment of the foyer at the New Street theatre that will be carried out over the summer.
