She sat in her room upstairs after the visitors had gone, thinking it over. The light was fading fast, and as she sat at the open window the remembrance of Mr. Tredgold's conduct helped to mar one of the most perfect evenings she had ever known. Downstairs the captain was also thinking. Dialstone Lane was in shadow, and already one or two lamps were lit behind drawn blinds. A little chatter of voices at the end of the lane floated in at the open window, mellowed by distance. His pipe was out, and he rose to search in the gloom for a match, when another murmur of voices reached his ears from the kitchen. He stood still and listened intently. To put matters beyond all doubt, the shrill laugh of a girl was plainly audible. The captain's face hardened, and, crossing to the fireplace, he rang the bell. "Yessir," said Joseph, as he appeared and closed the door carefully behind him. "What are you talking to yourself in that absurd manner for?" inquired the captain, with great dignity. "Me, sir?" said Mr. Tasker, feebly. "Yes, you," repeated the captain, noticing with surprise that the door was slowly opening. Mr. Tasker gazed at him in a troubled fashion, but made no reply. "I won't have it," said the captain, sternly, with a side glance at the door. "If you want to talk to yourself go outside and do it. I never heard such a laugh. What did you do it for? It was like an old woman with a bad cold." He smiled grimly in the darkness, and then started slightly as a cough, a hostile, challenging cough, sounded from the kitchen. Before he could speak the cough ceased and a thin voice broke carelessly into song. "WHAT!" roared the captain, in well-feigned astonishment. "Do you mean to tell me you've got somebody in my pantry? Go and get me those rules and regulations." Mr. Tasker backed out, and the captain smiled again as he heard a whispered discussion. Then a voice clear and distinct took command. "I'll take 'em in myself, I tell you," it said. "I'll rules and regulations him." The smile faded from the captain's face, and he gazed in perplexity at the door as a strange young woman bounced into the room. "Here's your rules and regulations," said the intruder, in a somewhat shrewish voice. "You'd better light the lamp if you want to see 'em; though the spelling ain't so noticeable in the dark." The impressiveness of the captain's gaze was wasted in the darkness. For a moment he hesitated, and then, with the dignity of a man whose spelling has nothing to conceal, struck a match and lit the lamp. The lamp lighted, he lowered the blind, and then seating himself by the window turned with a majestic air to a thin slip of a girl with tow-coloured hair, who stood by the door. "Who are you?" he demanded, gruffly.
