[386] Mrs. Turnbull finally agreed to the plan and Nancy went to the telephone. Captain Rossland readily agreed to send a man out a little later.
[387] "He'll return each night as long as you need him," the officer stated. "And I'll tell him not to ring the bell to tell you when he comes. If there is anyone who breaks into the mansion by a secret entrance, it would be much better if he does not know a guard is on duty."
[388] "I understand," said Nancy.
[389] When Miss Flora, her daughter, and the two girls went to bed, they were confident they would have a restful night. Nancy felt that if there was no disturbance, then it would indicate that the ghost's means of entry into Twin Elms was directly from the outside. "In which case," she thought, "it will mean he saw the guard and didn't dare come inside the house."
[390] The young sleuth's desire for a good night's sleep was rudely thwarted as she awakened about midnight with a start. Nancy was sure she had heard a noise nearby. But now the house was quiet. Nancy listened intently, then finally got out of bed.
[391] "Perhaps the noise I heard came from outdoors," she told herself.
[392] Tiptoeing to a window, so that she would not awaken Helen, Nancy peered out at the moonlit grounds. Shadows made by tree branches, which swayed in a gentle breeze, moved back and forth across the lawn. The scent from a rose garden in full bloom was wafted to Nancy.
[393] "What a heavenly night!" she thought.
[394] Suddenly Nancy gave a start. A furtive figure had darted from behind a tree toward a clump of bushes. Was he the guard or the ghost? She wondered. As Nancy watched intently to see if she could detect any further movements of the mysterious figure, she heard padding footsteps in the hall. In a moment there was a loud knock on her door.
"Nancy! Wake up! Nancy! Come quick!"
[395] The voice was Miss Flora's, and she sounded extremely frightened. Nancy sped across the room, unlocked her door, and opened it wide. By this time Helen was awake and out of bed.
[396] "What happened?" she asked sleepily.
[397] Aunt Rosemary had come into the hall also. Her mother did not say a word; just started back toward her own bedroom. The others followed, wondering what they would find. Moonlight brightened part of the room, but the area near the hall was dark.
[398] "There! Up there!" Miss Flora pointed to a corner of the room near the hall.
[399] Two burning eyes looked down on the watchers!
[400] Instantly Nancy snapped on the wall light and the group gazed upward at a large brown owl perched on the old-fashioned, ornamental picture molding.
[401] "Oh!" Aunt Rosemary cried out. "How did that bird ever get in here?"
[402] The others did not answer at once. Then Nancy, not wishing to frighten Miss Flora, remarked as casually as she could, "It probably came down the chimney."
[403] "But—" Helen started to say.
Nancy gave her friend a warning wink and Helen did not finish the sentence. Nancy was sure she was going to say that the damper had been closed and the bird could not possibly have flown into the room from the chimney. Turning to Miss Flora, Nancy asked whether or not her bedroom door had been locked.
[404] "Oh, yes," the elderly woman insisted. "I wouldn't leave it unlocked for anything."
[405] Nancy did not comment. Knowing that Miss Flora was a bit forgetful, she thought it quite possible that the door had not been locked. An intruder had entered, let the owl fly to the picture molding, then made just enough noise to awaken the sleeping woman.
[406] To satisfy her own memory about the damper, Nancy went over to the fireplace and looked inside. The damper was closed.
[407] "But if the door to the hall was locked," she reasoned, "then the ghost has some other way of getting into this room. And he escaped the detection of the guard."
[408] "I don't want that owl in here all night," Miss Flora broke into Nancy's reverie. "We'll have to get it out."
[409] "That's not going to be easy," Aunt Rosemary spoke up. "Owls have very sharp claws and beaks and they use them viciously on anybody who tries to disturb them. Mother, you come and sleep in my room the rest of the night. We'll chase the owl out in the morning."
