Тайна загадочной лестницы [with w_cat] | страница 31

[443] "I'll tell you my theory," said Nancy. "I believe there's a secret underground entrance from some other place on the grounds. It may be in one of these outbuildings. Anyway, tomorrow morning I'm going on a search for it."

[444] "Well, I wish you luck," Tom Patrick said. "And if anything happens during the night, I'll let you know."

Nancy pointed to a window on the second floor. "That's my room," she said. "If you don't have a chance to use the door knocker, just throw a stone up against the screen to alert me. I'll wake up instantly, I know."

[445] The guard promised to do this and Nancy went back into the mansion. She climbed the stairs and for a second time that night undressed. Helen had already gone back to sleep, so Nancy crawled into the big double bed noiselessly.

[446] The two girls awoke the next morning about the same time and immediately Helen asked for full details of what Nancy had learned outdoors the night before. After hearing how her friend had been stopped by the guard, she shivered.

[447] "You might have been in real danger, Nancy, not knowing who he was. You must be more careful. Suppose that man had been the ghost?"

[448] Nancy laughed but made no reply.   The girls went downstairs and started to prepare breakfast. In a few minutes Aunt Rosemary and her mother joined them.

[449] "Did you find out anything more last night?" Mrs. Hayes asked Nancy.

[450] "Only that a police guard named Tom Patrick is on duty," Nancy answered.

[451] As soon as breakfast was over, the young sleuth announced that she was about to investigate all the outbuildings on the estate.

[452] "I'm going to search for an underground passage leading to the mansion. It's just possible that we hear no hollow sounds when we tap the walls, because of double doors or walls where the entrance is."

[453] Aunt Rosemary looked at Nancy intently. "You are a real detective, Nancy. I see now why Helen wanted us to ask you to find our ghost."

[454] Nancy's eyes twinkled. "I may have some instinct for sleuthing," she said, "but unless I can solve this mystery, it won't do any of us much good."

[455] Turning to Helen, she suggested that they put on the old clothes they had brought with them.

[456] Attired in sport shirts and jeans, the girls left the house. Nancy led the way first to the old icehouse. She rolled back the creaking, sliding door and gazed within. The tall, narrow building was about ten feet square. On one side were a series of sliding doors, one above the other.
