A telegram sent by British actor and playwright Noel Coward to Agatha Christie from Bermuda has been recovered after it was found hidden in the back of an old bureau.The message is dated September 1957 and was sent from Bermuda to London. Mr Coward wrote to congratulate the writer on the recent success of her play ‘The Mousetrap’, which overtook his own play, ‘Blithe Spirit’, as the longest running in the West End.Mr Coward wrote: “Dear Agatha Christie, much as it pains me I really must congratulate you on The Mousetrap breaking the long run record. All my good wishes, Noel Coward.”Mr Coward briefly resided in Bermuda for two years during the 1950s after he bought Spithead Lodge on Harbour Road in Warwick.According to his longtime partner, Graham Payne, Mr Coward did not take well to the island’s warm climate.Mr Payne recalled: “Oh, it was a terrible time we went through! But he loved it.“It was very hot, as you know, in Bermuda in the summer and when he was in the kitchen, he didn’t wear any clothes at all, virtually nothing, except a little apron a plastic thing here in front, was all.”He originally moved to the island to escape what he considered to be the unjust tax situation in England at the time.The bureau containing the telegram had been recently auctioned off and furniture restorer Clive Payne, from Gloucestershire, in the South West UK, was commissioned by the owner to repair it. He discovered the message in the back of the bureau.“As part of the restoration process I needed to remove its back. The usual dirt and muck fell out, but also two pieces of paper,” Mr Payne said. The discovery also confirmed the bureau’s previous owner had been Ms Christie.Ms Christie’s grandson, Mathew Prichard, added that his grandmother greatly valued the opinions of her peers.He said: “I’d have thought to have had acknowledgment at The Mousetrap running so long would have pleased her very much”. He also confirmed that Ms Christie greatly admired Mr Coward.Today Ms Christie is the best-selling author of all time, along with William Shakespeare, according to the Guinness Book of Records.
