the filling station to have the tank refueled. He rejoined them soon, shaking the raindrops from his coat.

“It’s coming down harder than ever,” he reported. “And we still have a long drive ahead of us.”

“Do you think we’ll reach our camp site tonight, Dad?” Penny inquired anxiously.

“We’ll be lucky to get to Sunset Beach. As for making camp, that’s out of the question.”

“Maybe it will stop raining soon,” Penny ventured hopefully.

Mr. Parker ordered dinner for the party and an hour was consumed in dining. The rain, however, showed no signs of slackening.

“We could go on—” Mr. Parker said thoughtfully. “Of course, the roads are slippery.”

“Oh, please let’s not venture out in this,” Mrs. Deline pleaded before Penny could speak. “I know I am being silly, but I’m so afraid of an accident. Once I was in a car that overturned and I’ve never forgotten it.”

“There’s no great hurry,” Mr. Parker replied. “If we can’t reach Sunset Beach tonight, I suppose we could stay here.”

Mrs. Deline did not comment upon the suggestion, but from the way she smiled, Penny was sure that the idea appealed to her. Taking her father aside, the girl urged him to try to drive on to Sunset Beach that night.

“Our vacation is so short, Dad. Even now we’ll lose almost a day in setting up camp.”

“We’ll certainly push on if we can,” he promised. “This storm complicates everything.”

For two hours the rain fell steadily. With the prospects anything but improved, Mr. Parker made inquiry as to lodging for the night. From the hotel keeper he learned that rooms already were at a premium.

“We’ll have to make up our minds soon,” he reported to Penny and Mrs. Deline. “If we wait much longer we’ll probably find ourselves sleeping in the lobby.”

“Then let’s stay,” the widow urged. “Please engage a room and a bath for me. Preferably one at the rear of the building away from the highway.”

“I’m afraid you’ll have no choice,” Mr. Parker told her regretfully. “We’ll have to take what we can get.”

The publisher consulted with the hotel clerk, and returned to report that only two rooms remained available.

“You and Penny will have to share one together,” he explained. “I hope you won’t mind.”

It was evident by the expression of Mrs. Deline’s face that she minded a great deal. However, she consented to the arrangement and the luggage was taken upstairs. The door closed behind the bellboy. For the first time Penny and Mrs. Deline were left alone.

“Such a cheap, dirty hotel!” the widow exclaimed petulantly. “And I do hate to share a room with anyone.”

Penny busied herself unpacking her over-night bag. Crossing to the window, she raised it half way.

“Do put that down!” Mrs. Deline ordered. “I detest air blowing directly on me.”

Penny lowered the window.

Mrs. Deline smoked a cigarette, carelessly allowing the ashes to fall on the bed. Getting up, she moved nervously about the room.

“This place is so small it seems like a prison,” she complained. “Why do you sit there and stare at me?”

“I didn’t realize I was staring,” Penny apologized. “If you’ll excuse me, I’ll go to bed.”

Undressing quickly, she crawled beneath the covers. Mrs. Deline smoked still another cigarette and then began to prepare for bed. As she removed the jacket of her suit, Penny noticed that the woman wore a beautiful jade elephant pin.

“Why, what an attractive ornament!” she exclaimed. “Is it a locket or just a pin?”

“I bought it in China,” the widow answered without replying to the question.

“In China! Have you been there?”

“Of course!” Mrs. Deline gave Penny an amused glance. Without removing the pin or offering to show it to the girl, she completed her preparations for bed.

Just at that moment there came a light tap on the door.

“Oh, Penny!” Mr. Parker called.

“Yes, Dad, what is it?” Penny leaped out of bed.

“I’m worried about the car keys,” he called through the transom. “You didn’t by chance see them after we left the dining room?”

“Why, yes,” Penny reassured him. “You left them lying on the table. I picked them up and forgot to tell you. They’re here on the dresser. I’ll hand them out.”

“No, never mind. Keep them. I was just afraid they were lost. Goodnight.”

Mrs. Deline glanced curiously at the key ring on the dresser. She remarked that she had not seen Penny pick it up.

“You were talking to Dad at the time,” the girl replied.

Leaving the keys on the dresser, she leaped into bed again and settled herself for a comfortable sleep. Mrs. Deline presently turned out the light and took the other bed. For a time Penny was annoyed by voices from the hallway, then all became quiet. She slept.

Much later Penny awoke. She stirred and rolled over. The rain had ceased and moonlight was flooding into the room. A beam fell directly across Mrs. Deline’s bed, revealing a mass of crumpled sheets and covers.

Penny stared, scarcely believing her eyes. The bed was empty.

CHAPTER
3
A JADE GREEN CHARM

Sitting up in bed, Penny gazed about the room. Mrs. Deline was not there and her clothes were gone from the chair where they had been placed earlier that night.

“Queer,” mused the girl.

Jumping out of bed, she darted to the door. Though it had been carefully locked a few hours before, the latch now was off.

Thoroughly puzzled, Penny switched on a light and glanced carefully about. Mrs. Deline’s suitcase remained in the closet, but coat and hat were missing. And then Penny made an even more disturbing discovery. The car keys were gone from the dresser!

“Why, I know I put those keys on the bureau just before I went to bed!” she told herself in dismay. “Now I wonder if that woman—” Ashamed of her thoughts, she muttered: “Guess I am a suspicious brat!”

Deeply mystified, she moved quickly to the window overlooking the parking lot and filling station. It was reassuring to see the Parker automobile standing where her father had left it earlier that night. But as she stood staring down into the dark, deserted yard, she was startled to observe a shadowy figure rounding a corner of the hotel.

“Mrs. Deline!” she recognized the woman.

Penny waited only long enough to see that the widow was walking straight toward the Parker sedan.

“She intends to steal it!” thought the girl. “Why else would she take the keys?”

Snatching dress and coat from a chair, Penny scrambled into them without taking time to remove her pajamas. She tucked up the unsightly legs of the garment and put on her shoes. Thus clad she ran downstairs through the semi-dark lobby to the side exit of the hotel.

As she reached the outside door, she heard the blast of an automobile engine.

“That’s our car!” Penny thought, recognizing the sound of the running motor. “She’ll get away before I can stop her!”

The engine, evidently cold, sputtered a moment, then died.

Hopeful that she might still get there in time, Penny raced across the parking lot. Reaching the car just as it started to move backwards, she jerked open the door.

“Mrs. Deline!” she cried.

Startled, the woman released the clutch so suddenly that the motor died again.
