Puzzled, the young sleuth hurried down the steps and began a search of the grounds. By this time Helen had collected her wits and come outside. She joined Nancy and together they looked in every outbuilding and behind every clump of bushes on the grounds of Twin Elms. They did not find one footprint or any other evidence to prove that a gorilla or other creature had been on the grounds of the estate.

  “I saw it! I know I saw it!” Helen insisted.

  “I don’t doubt you,” Nancy replied.

  “Then what explanation is there?” Helen demanded. “You know I never did believe in spooks. But if we have many more of these weird happenings around here, I declare I’m going to start believing in ghosts.”

  Nancy laughed. “Don’t worry, Helen,” she said. “There’ll be a logical explanation for the face at the window.”

  The girls walked back to the front door of the mansion. Miss Flora and Aunt Rosemary stood there and immediately insisted upon knowing what had happened. As Helen told them, Nancy once more surveyed the outside of the window at which Helen had seen the terrifying face.

  “I have a theory,” she spoke up. “Our ghost simply leaned across from the end of the porch and held a mask in front of the window.” Nancy stretched her arm out to demonstrate how this was possible.

  “So that’s why he didn’t leave any footprints under the window,” Helen said. “But he certainly got away from here fast.” She suddenly laughed. “He must be on some ghosts’ track team.”

  Her humor, Nancy was glad to see, relieved the tense situation. She had noticed Miss Flora leaning wearily on her daughter’s arm.

  “You’d better lie down and rest, Mother,” Mrs. Hayes advised.

  “I guess I will,” Aunt Flora agreed.

  It was suggested that the elderly woman use Aunt Rosemary’s room, while the others continued the experiment with the chandelier.

  Helen and Aunt Rosemary went into the parlor and waited as Nancy ascended the front stairway and went to Miss Flora’s bedroom. Once more she began to rock from side to side. Downstairs, Aunt Rosemary and her niece were gazing intently at the ceiling.

  “Look!” Helen exclaimed, pointing to the crystal chandelier. “It’s moving!” In a moment it swung to the left, then back to the right.

  “Nancy has proved that the ghost was up in my mother’s room!” Aunt Rosemary said excitedly.

  After a few minutes the rocking motion of the chandelier slackened and finally stopped. Nancy came hurrying down the steps.

  “Did it work?” she called.

  “Yes, it did,” Aunt Rosemary replied. “Oh, Nancy, we must have two ghosts!”

  “Why do you say that?” Helen asked.

  “One rocking the chandelier, the other holding the horrible face up to the window. No one could have gone from Miss Flora’s room to the front porch in such a short time. Oh, this complicates everything!”

  “It certainly does,” Nancy agreed. “The question is, are the two ghosts in cahoots? Or, it’s just possible, there is only one. He could have disappeared from Miss Flora’s room without our seeing him and somehow hurried to the first floor and let himself out the front door while we were upstairs. I’m convinced there is at least one secret entrance into this house, and maybe more. I think our next step should be to try to find it—or them.”

  “We’d better wash the luncheon dishes first,” Aunt Rosemary suggested.

  As she and the girls worked, they discussed the mystery, and Mrs. Hayes revealed that she had talked to her mother about leaving the house, whether or not she sold it.

  “I thought we might at least go away for a little vacation, but Mother refuses to leave. She says she intends to remain right here until this ghost business is settled.”

  Helen smiled. “Nancy, my great-grandmother is a wonderful woman. She has taught me a lot about courage and perseverance. I hope if I ever reach her age, I’ll have half as much.”

  “Yes, she’s an example to all of us,” Aunt Rosemary concurred.

  Nancy nodded. “I agree. I haven’t known your mother long, Aunt Rosemary, but I think she is one of the dearest persons I’ve ever met.”

  “If Miss Flora won’t leave,” said Helen, “I guess that means we all stay.”

  “That’s settled,” said Nancy with a smile.

  After the dishes were put away, the girls were ready to begin their search for a secret entrance into the mansion.

  “Let’s start with Miss Flora’s room,” Helen suggested.

  “That’s a logical place,” Nancy replied, and took the lead up the stairway.

  Every inch of the wall, which was paneled in maple halfway to the ceiling, was tapped. No hollow sound came from any section of it to indicate an open space behind. The bureau, dressing table, and bed were pulled away from the walls and Nancy carefully inspected every inch of the paneling for cracks or wide seams to indicate a concealed door.

  “Nothing yet,” she announced, and then decided to inspect the sides of the fireplace.

  The paneled sides and brick front revealed nothing. Next, Nancy looked at the sides and rear of the stone interior. She could see nothing unusual, and the blackened stones did not look as if they had ever been disturbed.

  She closed the damper which Helen had left open, and then suggested that the searchers transfer to another room on the second floor. But no trace of any secret entrance to the mansion could be found.

  “I think we’ve had enough investigation for one day,” Aunt Rosemary remarked.

  Nancy was about to say that she was not tired and would like to continue. But she realized that Mrs. Hayes had made this suggestion because her mother was once more showing signs of fatigue and strain.

  Helen, who also realized the situation, said, “Let’s have an early supper. I’m starved!”

  “I am, too,” Nancy replied, laughing gaily.

  The mood was contagious and soon Miss Flora seemed to have forgotten about her mansion being haunted. She sat in the kitchen while Aunt Rosemary and the girls cooked the meal.

  “Um, steak and French fried potatoes, fresh peas, and yummy floating island for dessert,” said Helen. “I can hardly wait.”

  “Fruit cup first,” Aunt Rosemary announced, taking a bowl of fruit from the refrigerator.

  Soon the group was seated at the table. Tactfully steering the conversation away from the mystery, Nancy asked Miss Flora to tell the group about parties and dances which had been held in the mansion long ago.

  The elderly woman smiled in recollection. “I remember one story my husband told me of something that happened when he was a little boy,” Miss Flora began. “His parents were holding a masquerade and he was supposed to be in bed fast asleep. His nurse had gone downstairs to talk to some of the servants. The music awakened my husband and he decided it would be great fun to join the guests.

  “ ‘I’ll put on a costume myself,’ he said to himself. He knew there were some packed in a trunk in the attic.” Miss Flora paused. “By the way, girls, I think that sometime while you are here you ought to see them. They’re beautiful.

  “Well, Everett went to the attic, opened the trunk, and searched until he found a soldier’s outfit. It was very fancy—red coat and white trousers. He had quite a struggle getting it on and had to turn the coat sleeves way up. The knee britches came to his ankles, and the hat was so large it came down over his ears.”

  By this time Miss Flora’s audience was laughing and Aunt Rosemary remarked, “My father really must have looked funny. Please go on, Mother.”

  “Little Everett came down the stairs and mingled with the masqueraders at the dance. For a while he wasn’t noticed, then suddenly his mother discovered the queer-looking figure.”

  “And,” Aunt Rosemary interrupted, “quickly put him back to bed, I’m sure.”

  Miss Flora laughed. “That’s where you’re wrong. The guests thought the whole thing was such fun that they insisted Everett stay. Some of the women danced with him—he went to dancing school and was an excellent dancer. Then
they gave him some strawberries and cream and cake.”

  Helen remarked, “And then put him to bed.”

  Again Miss Flora laughed. “The poor little fellow never knew that he had fallen asleep while he was eating, and his father had to carry him upstairs. He was put into his little four-poster, costume and all. Of course his nurse was horrified, and I’m afraid that during the rest of the night the poor woman thought she would lose her position. But she didn’t. In fact, she stayed with the family until all the children were grown up.”

  “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 VII

  Frightening 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.”

  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.

  To satisfy her own memory about the damper, Nancy went over to the fireplace and looked inside. The damper was closed.

  “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.”

  “I don’t want that owl in here all night,” Miss Flora broke into Nancy’s reverie. “We’ll have to get it out.”

  “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.”

  Nancy urged Miss Flora to go with her daughter. “I’ll stay here and try getting Mr. Owl out of the house. Have you a pair of old heavy gloves?”

  “I have some in my room,” Aunt Rosemary replied. “They’re thick leather. I use them for gardening.”

  She brought them to Nancy, who put the gloves on at once. Then she suggested that Aunt Rosemary and her mother leave. Nancy smiled. “Helen and I will take over Operation Owl.”

  As the door closed behind the two women, Nancy dragged a chair to the corner of the room beneath the bird. She was counting on the fact that the bright overhead light had dulled the owl’s vision and she would be able to grab it without too much trouble.

  “Helen, will you open one of the screens, please?” she requested. “And wish me luck!”

  “Don’t let that thing get loose,” Helen warned as she unfastened the screen and held it far out.

  Nancy reached up and by stretching was just able to grasp the bird. In a lightning movement she had put her two hands around its body and imprisoned its claws. At once the owl began to bob its head and peck at her arms above the gloves. Wincing with pain, she stepped down from the chair and ran across the room.

  The bird squirmed, darting its beak in first one direction, then another. But Nancy managed to hold the owl in such a position that most of the pecking missed its goal. She held the bird out the window, released it, and stepped back. Helen closed the screen and quickly fastened it.
