First he had tried to ascertain whether any one had recently had access to Mr. Duke’s dressing-room during the night or early morning, and he soon learned that, prior to his own visit, no tradesmen had been in the house for many months. Moreover, the only visitor who had stayed overnight for a considerable time was Mr. Stanley Harrington, Miss Duke’s _fiancée_. The two young people had been feverishly engaged in rehearsals for a play given by a local amateur dramatic society, and for the four nights previous to the entertainment Miss Duke had refused to allow her swain to waste time in going to and from his rooms, and had insisted on his putting up with them. This occurred about a month before the murder, and Harrington had slept in a room just opposite to Mr. Duke’s. It was obvious, therefore, that had the key been left in the dressing-room at any time, Harrington could easily have taken the necessary impression. Nolan then went on to tell what he had found out as to the postponed wedding, and in this French felt he had food for thought. It appeared that the trouble, whatever it was, had come suddenly, and it had taken place on the day after the murder. On the evening of the crime, so Rachael had said, Mr. Duke was not at home for dinner, but Mr. Harrington had turned up. He and Miss Duke had dined together, and then everything was _couleur de rose_. They had gone out together after dinner. About ten, Miss Duke had returned and had gone straight to bed. Almost certainly, therefore, she had not known that night of Mr. Duke’s call to the office. Next morning she had breakfasted with her father, and had presumably then learned of the tragedy. But not five minutes after breakfast began she had slipped out of the room and had made a telephone call, and directly Mr. Duke had left the house she had put on her things and followed him. She had been absent for about twenty minutes, and had then gone direct to her bedroom, where, on the plea of a headache, she had spent the day. When Rachael had had occasion to enter, she found her lying down, but the girl had heard her hour after hour pacing the room, and in her opinion, her mistress’s indisposition was more mental than physical. About four o’clock that afternoon Mr. Harrington had called. Miss Duke saw him in her own sitting-room, and during the interview some terrible quarrel must have taken place. Mr. Harrington left in about half an hour, and Rachael, who had opened the door to let him out, said that he looked as if he had received his death warrant. His face wore an expression of the most acute consternation and misery, and he seemed like a man in a dream, stupefied by some terrible calamity. He usually spoke pleasantly to the girl when leaving, but on this occasion he did not appear to notice her presence, but stumbled blindly out of the house and crept off like a broken man. Later the same evening she had seen Miss Duke, and she noticed that her eyes were red and swollen from crying.
