To all men come portentous moments, difficult moments, triumphant moments. Loder had had his examples of all three, but no moment in his career ever equalled in strangeness of sensation that in which, dressed in another man's clothes, he fitted the latchkey for the first time into the door of the other man's house. The act was quietly done. The key fitted the lock smoothly and his fingers turned it without hesitation, though his heart, usually extremely steady, beat sharply for a second. The hall loomed massive and sombre despite the modernity of electric lights. It was darkly and expensively decorated in black and brown; a frieze of wrought bronze, representing peacocks with outspread tails, ornamented the walls; the banisters were of heavy iron-work, and the somewhat formidable fireplace was of the same dark metal. Loder looked about him, then advanced, his heart again beating quickly as his hand touched the cold banister and he began his ascent of the stairs. But at each step his confidence strengthened, his feet became more firm; until, at the head of the stairs, as if to disprove his assurance, his pulses played him false once more, this time to a more serious tune. From the farther end of a well-lighted corridor a maid was coming straight in his direction. For one short second all things seemed to whiz about him; the certainty of detection overpowered his mind. The indisputable knowledge that he was John Loder and no other, despite all armor of effrontery and dress, so dominated him that all other considerations shrank before it. It wanted but one word, one simple word of denunciation, and the whole scheme was shattered. In the dismay of the moment, he almost wished that the word might be spoken and the suspense ended. But the maid came on in silence, and so incredible was the silence that Loder moved onward, too. He came within a yard of her, and still she did not speak; then, as he passed her, she drew back respectfully against the wall. The strain, so astonishingly short, had been immense, but with its slackening came a strong reaction. The expected humiliation seethed suddenly to a desire to dare fate. Pausing quickly, he turned and called the woman back. The spot where he had halted was vividly bright, the ceiling light being directly above his head; and as she came towards him he raised his face deliberately and-waited. She looked at him without surprise or interest. “Yes, sir?” she said. “Is your mistress in?” he asked. He could think of no other question, but it served his purpose as a test of his voice. Still the woman showed no surprise. “She's not in sir,” she answered. “But she's expected in half an hour.” “In half an hour? All right! That's all I wanted.” With a movement of decision Loder walked back to the stair-head, turned to the right, and opened the door of Chilcote's rooms.
