[434] Nancy laughed lightly. "Anyway, you soon nabbed me," she told him.
[435] The two chatted for several minutes. Tom Patrick told Nancy that people in Cliffwood regarded Mrs. Turnbull as being a little queer. They said that if she thought her house was haunted, it was all in line with the stories of the odd people who had lived there from tune to time during the past hundred years or so.
[436] "Would this rumor make the property difficult to sell?" Nancy questioned the detective.
[437] "It certainly would."
[438] Nancy said she thought the whole thing was a shame. "Mrs. Turnbull is one of the loveliest women I've ever met and there's not a thing the matter with her, except that once in a while she is forgetful."
[439] "You don't think that some of these happenings we've heard about are just pure imagination?" Tom Patrick asked.
[440] "No, I don't."
[441] Nancy now told him about the owl in Miss Flora's bedroom. "The door was locked, every screen was fastened, and the damper in the chimney closed. You tell me how the owl got in there."
[442] Tom Patrick's eyes opened wide. "You say this happened only a little while ago?" he queried. When Nancy nodded, he added, "Of course I can't be everywhere on these grounds at once, but I've been round and round the building. I've never stopped walking since I arrived. I don't see how anyone could have gotten inside that mansion without my seeing him."
[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.
[457] "I've heard Miss Flora say," Helen spoke up, "that in days gone by huge blocks of ice were cut from the river when it was frozen over and dragged here on a sledge. The blocks were stored here and taken off from the top down through these various sliding doors."
[458] "That story rather rules out the possibility of any underground passage leading from this building," said Nancy. "I presume there was ice in here most of the year."
[459] The floor was covered with dank sawdust, and although Nancy was sure she would find nothing of interest beneath it, still she decided to take a look. Seeing an old, rusted shovel in one corner, she picked it up and began to dig. There was only dirt beneath the sawdust.
[460] "Well, that clue fizzled out," Helen remarked, as she and Nancy started for the next building.
[461] This had once been used as a smokehouse. It, too, had an earthen floor. In one corner was a small fireplace, where smoldering fires of hickory wood had once burned. The smoke had curled up a narrow chimney to the second floor, which was windowless.
[462] "Rows and rows of huge chunks of pork hung up there on hooks to be smoked," Helen explained, "and days later turned into luscious hams and bacon."
[463] There was no indication of a secret opening and Nancy went outside the small, two-story, peak-roofed structure and walked around. Up one side of the brick building and leading to a door above were the remnants of a ladder. Now only the sidepieces which had held the rungs remained.
[464] "Give me a boost, will you, Helen?" Nancy requested. "I want to take a look inside."
[465] Helen squatted on the ground and Nancy climbed to her shoulders. Then Helen, bracing her hands against the wall,, straightened up. Nancy opened the half-rotted wooden door.
[466] "No ghost here!" she announced.
[467] Nancy jumped to the ground and started for the servants' quarters. But a thorough inspection of this brick-and-wood structure failed to reveal a clue to a secret passageway.
[468] There was only one outbuilding left to investigate, which Helen said was the old carriage house. This was built of brick and was fairly large. No carriages stood on its wooden floor, but around the walls hung old harnesses and reins. Nancy paused a moment to examine one of the bridles. It was set with two hand-painted medallions of women's portraits.
[469] Suddenly her reflection was interrupted by a scream. Turning, she was just in time to see Helen plunge through a hole in the floor. In a flash Nancy was across the carriage house and looking down into a gaping hole where the rotted floor had given way.
[470] "Helen!" she cried out in alarm.
[471] "I'm all right," came a voice from below. "Nice and soft down here. Please throw me your flash."
[472] Nancy removed the flashlight from the pocket of her jeans and tossed it down.
[473] "I thought maybe I'd discovered something," Helen said. "But this is just a plain old hole. Give me a hand, will you, so I can climb up?"
[474] Nancy lay flat on the floor and with one arm grabbed a supporting beam that stood in the center of the carriage house. Reaching down with the other arm, she assisted Helen in her ascent.
[475] "We'd better watch our step around here," Nancy said as her friend once more stood beside her.
[476] "You're so right," Helen agreed, brushing dirt off her jeans. Helen's plunge had given Nancy an idea that there might be other openings in the floor and that one of them could be an entrance to a subterranean passage. But though she flashed her light over every inch of the carriage-house floor, she could discover nothing suspicious.
