"Oh, that's a wonderful story!" said Nancy.
She was about to urge Miss Flora to tell another story when the telephone rang. Aunt Rosemary answered it, and then called to Nancy, "It's for you."
Nancy hurried to the hall, grabbed up the phone, and said, "Hello." A moment later she cried out, "Dad! How wonderful to hear from you!"
Mr. Drew said that he had not found Willie Wharton and certain clues seemed to indicate that he was not in Chicago, but in some other city.
"I have a few other matters to take care of that will keep me here until tomorrow night. How are you getting along?"
"I haven't solved the mystery yet," his daughter reported. "We've had some more strange happenings. I'll certainly be glad to see you here at Cliffwood. I know you can help me."
"All right, I'll come. But don't try to meet me. The time is too uncertain, and as a matter of fact, I may find that I'll have to stay here in Chicago."
Mr. Drew said he would come out to the mansion by taxi. Briefly Nancy related her experiences at Twin Elms, and after a little more conversation, hung up. When she rejoined the others at the table, she told them about Mr. Drew's promised visit.
"Oh, I'll be so happy to meet your father," said Miss Flora. "We may need legal advice in this mystery."
There was a pause after this remark, with everyone silent for a few moments. Suddenly each one in the group looked at the others, startled. From somewhere upstairs came the plaintive strains of violin music. Had the radio been turned on again by the ghost?
Nancy dashed from the table to find out.
CHAPTER VIIFrightening Eyes
WITHIN five seconds Nancy had reached the second floor. The violin playing suddenly ceased.
She raced into Miss Flora's room, from which the sounds had seemed to come. The radio was not on. Quickly Nancy felt the instrument to see if it were even slightly warm to prove it had been in use.
"The music wasn't being played on this," she told herself, finding the radio cool.
As Nancy dashed from the room, she almost ran into Helen. "What did you find out?" her friend asked breathlessly.
"Nothing so far," Nancy replied, as she raced into Aunt Rosemary's bedroom to check the bedside radio in there.
This instrument, too, felt cool to the touch.
She and Helen stood in the center of the room, puzzled frowns creasing their foreheads. "There was music, wasn't there?" Helen questioned.
"I distinctly heard it," Nancy replied. "But where is the person who played the violin? Or put a disk on a record player, or turned on a hidden radio? Helen, I'm positive an intruder comes into this mansion by some secret entrance and tries to frighten us all."
"And succeeds," Helen answered. "It's positively eerie."
"And dangerous," Nancy thought.
"Let's continue our search right after breakfast tomorrow," Helen proposed.
"We will," Nancy responded. "But in the meantime I believe Miss Flora and Aunt Rosemary, to say nothing of ourselves, need some police protection."
"I think you're right," Helen agreed. "Let's go downstairs and suggest it to the others."
The girls returned to the first floor and Nancy told Mrs. Hayes and her mother of the failure to find the cause of the violin playing, and what she had in mind.
"Oh dear, the police will only laugh at us," Miss Flora objected.
"Mother dear," said her daughter, "the captain and his men didn't believe us before because they thought we were imagining things. But Nancy and Helen heard music at two different times and they saw the chandelier rock. I'm sure that Captain Rossland will believe Nancy and send a guard out here."
Nancy smiled at Miss Flora. "I shan't ask the captain to believe in a ghost or even hunt for one. I think all we should request at the moment is that he have a man patrol the grounds here at night. I'm sure that we're perfectly safe while we're all awake, but I must admit I'd feel a little uneasy about going to bed wondering what that ghost may do next."
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.
"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."
"I understand," said Nancy.
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."
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.
"Perhaps the noise I heard came from outdoors," she told herself.
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.
"What a heavenly night!" she thought.
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!"
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.
"What happened?" she asked sleepily.
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.
"There! Up there!" Miss Flora pointed to a corner of the room near the hall.
Two burning eyes looked down on the watchers!
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.
"Oh!" Aunt Rosemary cried out. "How did that bird ever get in here?"
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."
"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.
"Oh, yes," the elderly woman insisted. "I wouldn't leave it unlocked for anything."
