The first witness was the Duke of Denver, who claimed to have discovered the body. He gave evidence that he was coming into the house by the conservatory door at three o'clock in the morning of Thursday, October 14th, when his foot struck against something. He had switched on his electric torch and seen the body of Denis Cathcart at his feet. He had at once turned it over, and seen that Cathcart had been shot in the chest. He was quite dead. As Denver was bending over the body, he heard a cry in the conservatory, and, looking up, saw Lady Mary Wimsey gazing out horror-struck. She came out by the conservatory door, and exclaimed at once, "O God, Gerald, you've killed him!"
