Triss (All the Empty Towers)
From Tardis Wiki, the free Doctor Who reference
Triss was a rich man in the late 21st century. He owned the last snowy mountain in Switzerland. For his stag night in 2089, he and three of his friends rented out Blackpool Pleasure Beach, which had been abandoned and turned into a hunting ground. He tried to kill the Twelfth Doctor and Clara Oswald, who had arrived there by accident. (PROSE: All the Empty Towers)
