Dr Ashwan Chander, a 38-year-old eye specialist living in Chelsea, West London, was meeting some friends for an evening meal at a restaurant in Kensington High Street. He saw his last patient at Hayes Green Hospital in Putney and left the hospital at about 6.00 pm. After walking to a florist shop to buy some flowers, he took a taxi to his mothers house in Fulham. He then intended to take another taxi from his mothers house to meet his friends at the restaurant at the agreed time of 8.00 pm. However, because the traffic was at a standstill, Dr Chander thought it best to walk and eventually arrived at the restaurant at about 8.20 pm. Later, when he went to pay the bill at the restaurant he found that he had lost his wallet. It is also known that: Dr Chander took money out of his wallet to pay for the flowers. Dr Chander did not take money from his wallet to pay for the taxi. The wallet was usually in Dr Chanders jacket, which he placed on the back of his chair in the restaurant.
