Three Coins in a Fountain

S8 E4: One Sunday morning, the Brokenwood fountain is spraying reddish-brown water-due to a man impaled on its sculpture. The victim is an American tourist who has three gold coins secreted in various places on his person. These clues point to the curious sport of spoofing, and the detectives soon narrow their suspects down to the fellow competitors at the previous night's spoofing championship.
