“Don’t talk any more now,” said John, as Helen sighed wearily. “We’ll go back to the cottage and Nancy will put you to bed.”
John carried Helen, and with Nancy’s guiding light, headed toward the cottage. They had hardly started when the trio was startled by a loud boo-oo-m! It seemed to come from the direction of the cottages!
“That sounded like an explosion!” cried Nancy. She broke into a run.
John, carrying Helen, followed as fast as he could. A moment later Nancy heard a crackling noise and smelled smoke.
“John!” Nancy cried in horror. “Look! Our cottage is on fire!”
The young people stared ahead in dismay. Tongues of orange-red flames were indeed shooting upward from the girls’ cottage! The trio could already feel the heat from the blaze.
“We’ll have to douse it,” John said tensely. “The whole row will burn down if we wait for the fire department.”
Helen insisted she was strong enough to walk. “I can help!”
John raced to the side of the inn where an extension water hose was attached. “Get the buckets near the kitchen door!” he shouted to the girls.
They dashed toward the inn. At the same time, the hall lights came on and the front door was flung open. Emily, Maud, and Mrs. Willoughby, dressed in robes, rushed out. Behind them was Mr. Daly, carrying a Revolutionary War musket!
Each group was amazed to see the other but Nancy took no time asking questions. “Our cottage is on fire!” she announced.
Soon everyone joined in tossing bucket after bucket of water from a garden spigot onto the blaze. John played a steady stream from the hose. Gradually the blaze was reduced to embers.
“Glad we saved the other units, anyhow,” John said, glancing at the ruined guest cottage. “Too bad you girls lost all your clothes.”
“But saved our lives by not being in the cottage,” Nancy remarked grimly.
“How did the fire start? What caused that explosion?” Emily asked, explaining that she and the others had been awakened by the noise.
“I believe,” Nancy said gravely, “it was caused by a time bomb which someone placed in our cottage before we went to bed. A ticking sound woke me. I thought it was my clock.”
Her listeners were shocked. Mrs. Willoughby grew deathly pale, as Maud shrilled, “There must be a lunatic loose around here.”
For once Nancy was inclined to agree with her. The young sleuth added that of course nothing could be determined until daylight when the ruins would be examined.
The exhausted group went back to the inn. “Nancy and Helen,” Emily said, “I feel terrible about this whole thing.”
Mrs. Willoughby, too, expressed her regret. “At least some of the loss will be covered by our fire insurance,” she added.
Nancy smiled and nodded, then started to relate Helen’s startling experience just before the fire.
When Nancy came to the part about the woman in the white robe, Emily shivered. “I don’t believe in ghosts,” she averred, “but Mary Mason probably saw this person. That’s why she said Lilac Inn was haunted!”
Nancy suddenly noticed how pale Helen was and suggested she get to bed at once.
“Oh, yes,” said Emily. “Nancy and Helen, take the front second-floor bedroom.”
Nancy noticed that Mr. Daly still clutched the ancient musket. With a sheepish smile, he said, “Shortly before the explosion, I thought I heard someone prowling around outside. I grabbed this old musket—guess it’s been here since the inn was built. It’s not loaded, but I figured it might scare away an intruder.”
John grinned. “Nancy and I were your ‘prowlers.’ ” He explained that they had tried all the doors in their search for Helen.
The women and girls started upstairs. John and Mr. Daly, carrying his musket, said they would “stand guard” for the rest of the night.
As Emily showed Nancy and Helen to their room, she said firmly, “This awful experience has made me decide to call the police first thing in the morning!”
“Oh, Emily, thank goodness!” Helen exclaimed in relief. “If there is some kind of maniac loose at Lilac Inn, you’ll be doing the right thing.”
Emily stepped closer to the girls. “When the police arrive,” she whispered, “I’d appreciate it if you still don’t mention the diamond theft.”
Her friends, though surprised, promised not to say a word about it.
“You see,” Emily went on softly, “it’s not for my sake, but Aunt Hazel’s. I can’t explain any more right now. You go to bed. I’ll call you if I need you.”
Nancy and Helen were too polite to ask further questions. Nevertheless, Nancy fell asleep wondering about Emily’s request. When the young sleuth awoke in the morning, her first thought was of the bomb. When had it been planted? While she was skin diving?
“The person who placed the bomb might have been seen by someone connected with the inn,” Nancy speculated.
Helen awoke just then, and Nancy asked how she felt. “Fine, except for a slight headache.” Helen shuddered. “Last night seems like a terrible dream!”
A few minutes later Emily knocked on the door with clothes for Helen and Nancy to borrow. While they dressed, she reported that a trooper from the Benton State Police Barracks would be over shortly to inspect the burned cottage.
“John checked the lilac grove at daybreak,” she added. “There were lots of footprints of various sizes, but no sign of any suspicious person.”
“Maybe I was dreaming I saw the ghost,” Helen said. She felt the back of her head. “But this bump is real!”
The three girls went down to breakfast. John, Mrs. Willoughby, and Maud were already at the table. No other guests were in the room. Nancy gave her order to Anna.
At a nearby table the waitress Jean Holmes was arranging flowers in a copper vase. The girl smiled shyly at Nancy, picked up the bowl, and walked toward the bay window. As she started to place the flowers on the wide sill, Jean gave a startled cry. She dropped the bowl, scattering flowers and water on the floor.
Everyone at the table stared out the window. Two men were peering in. Nancy recognized them and jumped to her feet in surprise.
CHAPTER X
“Blue Pipes”
THE unexpected sight of the two men peering through the dining-room window had startled Nancy, but in a happy way. She recognized the observers as her father and the state trooper, Lieutenant Brice.
As Jean apologized for her clumsiness and went to the kitchen for her broom and mop, Nancy hurried to the hall. She greeted her tall, handsome father and the officer who had come to her rescue when her car was forced into the ditch.
“Nancy, are you all right?” was Carson Drew’s first question.
“Oh, just fine, Dad. What a nice surprise to see you!” She kissed him affectionately. With a smile she added, “I didn’t expect to see you again so soon, Lieutenant Brice.”
The officer grinned. He explained that he had been assigned to investigate the cottage fire. When he arrived at Lilac Inn, he had met Carson Drew, who had just driven up. The two men were completing a quick tour of the grounds when they passed the dining room and looked in.
Mr. Drew chuckled. “I thought I’d surprise you, Nancy, but I didn’t expect to scare that waitress.”
“So many upsetting things have happened here, Dad,” Nancy said, “I guess everyone’s a bit nervous.”
Mr. Drew said that until he had met the officer in the parking lot, he had heard nothing of the trouble at Lilac Inn.
“The lieutenant mentioned last night’s explosion and fire here. Then he asked if I were the father of the Nancy Drew who had the accident on the side road to Benton.”
“You haven’t talked to Hannah?” Nancy asked.
“No. I came directly here.” Mr. Drew put an arm around his daughter. “I’m concerned about you.
“I’m all right, Dad,” Nancy insisted. “Really I am. By the way, have you talked to Chief McGinnis?”
“Yes. That’s another re
ason I came here,” her father said. “I had to phone him on a legal matter. He told me that you found the charge plate and the envelope with your name on it. By the way, there were no helpful prints on either the plate or the envelope.”
Nancy decided to wait before telling her father of the other mysterious incidents, and now suggested that the men come into the dining room to breakfast. She made the necessary introductions. The Willoughbys and Mr. Drew were well acquainted and exchanged warm greetings.
Maud fluttered her eyelashes. “So you’re the famous criminal lawyer,” she said coyly.
Carson Drew did not like flattery, but nodded politely. He congratulated Emily on her forthcoming marriage. When the men had finished eating, Nancy and her friends went with them to see the burned cottage.
Emily told Lieutenant Brice everything that had happened but excluded the diamond theft. He rubbed his chin thoughtfully, then said, “All could be malicious pranks, not connected with the explosion. On the other hand, they could very well be part of some big scheme.”
When the group reached the site of the burned cottage, they found John there. Nancy introduced him to her father and the police officer.
After Lieutenant Brice had probed the ruins of the cottage, Nancy and her friends gave him and Mr. Drew a full account of the previous night’s events. When he heard of Helen’s experience, Mr. Drew looked grave and suggested she return home.
Helen shook her head. “I can’t desert Nancy.”
The young sleuth smiled gratefully. Secretly she longed to tell her father the rest of the story—the trip to Benton, the diamond turning up in her purse, the faked message from John, and her skin-diving adventure. But all these, Nancy realized, were related to Emily’s stolen gems.
Finally Lieutenant Brice announced, “I’ve found fragments of what I am positive was a time bomb you heard ticking, Miss Drew. I’ll send an explosives expert over to verify this, however.”
Carson Drew turned to his daughter. “Nancy, I wish I could stay here and help you work out this mystery. Unfortunately, I have to return to River Heights and review highly important evidence for a case I’m to try next week. But keep me posted.”
“I will, Dad. In fact, I may see you if I do some sleuthing near home, as I plan.”
Before leaving, Mr. Drew asked if Nancy had come upon any leads to her impersonator.
“Nothing definite, Dad,” was all Nancy could in truth reply.
The attorney then advised Emily to engage a guard to stand night duty. “I can recommend an excellent man,” he said. “His name is Carl Bard.”
Emily agreed and Mr. Drew went inside the inn to telephone him. He returned shortly and said Mr. Bard would report there later.
“Fine,” said Lieutenant Brice. “And I’ll have a squad car patrol the inn frequently. I suggest that no one venture out alone—especially at night—until this case is broken.”
Good-bys were exchanged, and Nancy stood waving to her father as he drove off. Meanwhile, Helen and Emily had started for the patio.
As Nancy hurried after them, she came to the tool shed. John had investigated it, but Nancy wondered if she might find some clue he had overlooked.
The door was open. She went inside. Spades, hoes, rakes, and other similar equipment lined the walls. Nancy studied the array. “Just ordinary garden tools,” she mused. Then suddenly she noticed a pad of notepaper lying on a bench. Nancy picked it up and turned the pages, which contained various notations for the gardeners. One item, on the third page and in a different kind of printing from the other instructions, read: “Prune blue pipes near grove.”
“ ‘Blue pipes,’ ” thought Nancy, as she tore out the sheet. “Now what does that mean? Could it possibly be a code message? Or a signal? I’ll ask the gardeners.”
She left the shed, and began to look for the men. The only man in sight was Gil, who was cutting the lawn with a power mower. She went up, and attracting his attention, asked him, “Can you tell me what ‘blue pipes’ are?”
“Never heard of ’em,” Gil replied laconically.
“One more question,” Nancy said. “Would you have any idea who used one of the inn’s canoes yesterday afternoon?”
For a moment Gil’s eyes narrowed. Then he brusquely replied No; he had not been near the dock all day. “Mr. John asked me the same thing. Well, I got work to do,” he muttered, and quickly resumed his mowing.
Nancy walked meditatively toward the inn. “If Gil doesn’t know what ‘blue pipes’ are, that message might well be a code phrase.”
It occurred to her that perhaps Mr. Daly would be able to explain the term. Nancy went inside and found the elderly gentleman in his office, going over receipts. He looked up as she knocked and entered.
“Good morning, Nancy. Sorry I missed meeting your father.”
Mr. Daly admitted that he had been wearied by his all-night vigil, and had gone to his room to rest. Nancy smiled understandingly and told him briefly of Lieutenant Brice’s investigation.
Mr. Daly looked grave. “If all this danger continues, I’m going to insist that Emily and Dick sell the inn. A nice young couple shouldn’t start marriage under such circumstances.”
“I agree. But the person responsible for the trouble here must be caught.”
“You’re right, Nancy,” Mr. Daly said, “I mustn’t lose hope so easily.”
The young sleuth then asked, “Mr. Daly, can you tell me what ‘blue pipes’ are?”
Mr. Daly chuckled. “Of course—my favorite subject matter is ‘blue pipes’—or lilacs.”
“You mean that ‘blue pipes’ are lilacs?” Nancy inquired with interest.
“Yes. The ancient name of the lilac was Blue Pipe Tree, a reminder of the time when pipes were made of its wood. See here.”
Mr. Daly reached into a drawer of his desk and handed Nancy a half-finished tobacco pipe. “Carving is my hobby. I’m making this pipe from the wood of a fallen tree limb right here at Lilac Inn.”
“Why, it’s beautiful!” Nancy held up the pipe, admiring the delicate stem.
At that moment Jean Holmes passed the office. She paused and looked in. Nancy greeted her, but the waitress barely answered. Her eyes were riveted on the pipe in Nancy’s hand.
“Isn’t this a handsome piece, Jean?” Nancy said pleasantly. “Mr. Daly made it.”
“Oh, very.” Jean nodded and hastened on into the dining room.
To Nancy it seemed that the waitress had acted almost frightened. Why?
Mr. Daly seemed not to have noticed. He went on to tell Nancy some interesting facts about lilacs. The old-fashioned, lavender-colored blossom and its white companion, so well known in America, originally came from Bulgaria, Hungary, and Rumania. But the double lilacs of pink, red, and purple, like those in the grove, were developed by horticulturists.
“The French developed the Lucie Baltet variety—the same as the stolen tree,” Mr. Daly said sadly. “Many beautiful lilacs are named after famous French people, such as Joan of Arc.”
“You’re certainly an expert on every aspect of lilacs,” Nancy complimented him as Mr. Daly paused.
Modestly, Mr. Daly admitted he had studied the subject intensively. He himself had planted most of the lilacs at the inn.
“They are considered a flower of mysterious power in the West Indies,” he said solemnly. “Some people there believe that the perfume keeps away ghosts and evil spirits. A lilac tree is often planted near the front door so its branches can act as protection against evil spirits entering the house.”
Nancy now pulled the sheet with the blue pipe notation from her pocket and passed it to Mr. Daly. “Do you know anything about this?” she asked.
He glanced at it and said, “No. And I write out all the instructions for the gardeners. I never use the term ‘blue pipes.’ They wouldn’t know what it meant.”
“Have you any idea who might have written this?” Nancy asked.
“None whatever. And I can’t figure out what it means. Besides, it’s
not time to prune lilacs. Have you a theory?”
“I’m not sure, except I have a hunch it’s connected with the strange happenings at Lilac Inn and is a code message. I hope I can figure it out.”
Nancy pocketed the sheet and left the office. Deep in thought, she almost bumped into Emily.
“Oh, where’s Detective Drew headed?”
The young sleuth laughed, then showed Emily the sheet. “Do you know who printed this strange notation?”
Emily stared at the message for several seconds. Finally she said, “No, but the printing looks familiar.”
“Think hard and don’t keep any secrets,” Nancy urged. “This may be the turning point in solving the mystery!”
Staring into space, Emily sought desperately for an answer. Suddenly she snapped her fingers. “I have it! That waitress who left here so suddenly! She used to print all the orders she took. I mean Mary Mason!”
CHAPTER XI
A Tip from a Waitress
“MARY MASON again!” exclaimed Nancy. “That settles it! I’m going to River Heights at once and talk to Mrs. Ernest Stonewell, the woman for whom she used to work.”
Nancy decided to tell Helen her plan, so the two girls went out to the patio where she was reading. Nancy revealed her latest findings and told of her proposed trip. “Want to come?” she asked Helen.
“No, thanks.” Helen chuckled. “You work better alone. What a clue this is! Maybe you’ll come back with the mystery solved!”
“Don’t count on that.” Nancy smiled. “Where is everybody?”
“John’s at the burned cottage with the explosives expert. Mrs. Willoughby and Maud are upstairs.”
Nancy leaned toward Emily and said in a low voice, “I hope you won’t mind my asking, but— but does Maud Potter have anything to do with your not reporting the diamond theft?”
Emily sighed. “Well, yes. You’ve probably sensed, Nancy, that she seems to have some influence over Aunt Hazel.”
