She walked boldly up to the entrance and passed through. The man she saw out of the corner of her eye but did not recognize. He seemed as little desirous of attracting attention as she. She thought he was rather stout and short, but as to this she was not sure. She raced up the stairs and turned on the landing to her room. The door of No. 4 was still ajar--but what was much more important, so was her door. There was no doubt about it, between the edge of the door and the jamb there was a good two inches of space, and she distinctly remembered not only closing it, but also pushing it to make sure that it was fast. What should she do? To her annoyance she felt a cold little feeling inside her and her hands were trembling. "If the lights were only on I'd take the risk," she thought; but the lights were not on and it was necessary to pass into the dark interior and into a darker bath-room--a room which is notoriously adaptable for murder--before she could reach the meter. "Rubbish, Matilda!" she scoffed quaveringly, "go in, you frightened little rabbit--you forgot to shut the door, that's all." She pushed the door open and with a shiver stepped inside. Then a sound made her stop dead. It was a shuffle and a creak such as a dog might make if he brushed against the chair. "Who's there?" she demanded. There was no reply. "Who's there?" She took one step forward and then something reached out at her. A big hand gripped her by the sleeve of her blouse and she heard a deep breathing. She bit her lips to stop the scream that arose, and with a wrench tore herself free, leaving a portion of a sleeve in the hands of the unknown. She darted backward, slamming the door behind her. In two flying strides she was at the door of No. 4, hammering with both her fists. "Drunk or sober he is a man! Drunk or sober he is a man!" she muttered incoherently. Only twice she beat upon the door when it opened suddenly and Mr. Beale stood in the doorway. "What is it?" She hardly noticed his tone. "A man--a man, in my flat," she gasped, and showed her torn sleeve, "a man...!" He pushed her aside and made for the door. "The key?" he said quickly. With trembling fingers she extracted it from her pocket. "One moment." He disappeared into his own flat and presently came out holding an electric torch. He snapped back the lock, put the key in his pocket and then, to her amazement, he slipped a short-barrelled revolver from his hip-pocket. With his foot he pushed open the door and she watched him vanish into the gloomy interior. Presently came his voice, sharp and menacing: "Hands up!" A voice jabbered something excitedly and then she heard Mr. Beale speak. "Is your light working?--you can come in, I have him in the dining-room." She stepped into the bath-room, the shilling dropped through the aperture, the screw grated as she turned it and the lights sprang to life.
