"It must have been during the last half hour. I went to the corner store for a book of stamps. When I came back five minutes ago I discovered what had occurred. I ought to call the police, but I am afraid to do it until I've talked with my employer."

"The police already have been notified," said Penny. "They'll be here any minute."

"But how did you know--?" the maid began in astonishment.

Penny had turned away. She was convinced that the burglary had been committed by Slippery. Perhaps, by this time he had fled town, but she did not believe he would leave without his pal, Al Gepper.

Climbing into the car again, Penny debated. It was reasonable to suppose that, having accomplished the burglary, Slippery would return to the Hodges' cottage to meet the medium.

"If he does, the police should be on hand to seize him," she thought. "At least, he and Al will be held for questioning. But there's one place I forgot to cover--the Celestial Temple."

Like a flash came the recollection that Slippery had been deeply interested in something which was guarded in the bell tower. Was it not possible that he might return there before leaving Riverview?

Shifting gears, Penny turned the car and headed for b.u.t.ternut Lane.

Anxiously, she glanced at the gasoline gauge. It registered less than a gallon of fuel and she had used her last dime in the telephone booth.

"If I coast on all the downgrades I should just make it," she estimated.

In starting for the Celestial Temple Penny was acting upon a "hunch."

However, it disturbed her that the Henley burglary had been accomplished, and she was afraid she might again be wasting precious time. Now that it was too late, she wondered if it would not have been wiser to remain at the Hodges' cottage until the police arrived.

"I only hope that end of the affair isn't bungled," she thought. "I'll never get over it if Al and Slippery both escape."

Penny had reached the entrance to b.u.t.ternut Lane. Parking at the side of the road, she continued afoot toward the Celestial Temple.

From a distance the building appeared dark. However, as she drew closer she could distinguish a dim light. Inside the Temple, a stout man wearing a hat sat with his chair tilted against the door of the bell tower room.

"He must be the guard," thought Penny. "Probably the one they call Pete."

Suddenly she paused, retreating into a clump of elder bushes near the walk. From the direction of the cemetery a figure emerged. At first, all that Penny could distinguish was a man carrying a suitcase. As he drew closer, her pulse quickened. Unmistakably, it was Slippery.

Without pa.s.sing the bushes where the girl had taken refuge, the man walked on toward the Temple. Presently he halted. Glancing carefully about to a.s.sure himself that he was un.o.bserved, he shoved his suitcase into the tall weeds which lined the walk. Then he moved to one of the Temple windows, peering into the gloomy interior.

"Now what?" thought Penny, watching alertly. "This should prove interesting."

Slippery remained beneath the window a minute or two. Instead of entering the Temple, he presently returned to the high weeds, stooping to remove some object from his suitcase. Hiding it under his coat, he circled the building and approached the side adjoining the cemetery.

Thoroughly mystified, Penny cautiously followed, taking care that her body cast no shadow which would attract Slippery's attention.

The man seemed deeply engrossed in the task he had set for himself. From his coat he took a collapsible rod which he extended to the approximate length of a fish pole. To its end he attached a trailing silken ladder.

Deftly the man raised the ladder until two metal hooks bit into a projection of the bell tower. He tested the ropes to make certain they would bear his weight then, with the agility of a cat, mounted the silken rungs. Penny saw him disappear into the bell tower.

"Now why did he climb up there?" she asked herself. "He must be after something hidden in the belfry."

Penny knew that she was a long distance from police aid, but it was unthinkable that Slippery should be allowed to escape. Impulsively, she moved from her hiding place to the base of the tower.

Grasping the silken ladder, she gave it a quick jerk which dislodged the two iron hooks. Down it tumbled into her arms, leaving the man trapped in the turret.

"He'll never dare call for help when he discovers what has happened,"

reasoned Penny. "If he does, the guard, Pete, will have something to say!"

Rolling the ladder into a small bundle, she started across the clearing, intending to seek the nearest telephone. With no thought of lurking danger, she brushed past a clump of bushes. A hand reached out and grasped her arm.

Penny screamed in terror and tried to break free. The hand help her in a grip of steel.

As she struggled, her captor emerged from the shelter of leaves. It was Al Gepper.

"I thought I might find you here, my little one," he said grimly. "You have had your fun. Now you must pay, and the entertainment shall be mine!"

CHAPTER 23 _A PRISONER IN THE BELFRY_

Penny tried to scream, only to have Al Gepper clamp his hand over her mouth.

"None of that!" he said harshly. "Behave yourself or you'll get rough treatment."

Inside the Temple, lights suddenly were turned on, for the brief struggle had been heard by Pete. The squat, stupid-faced man appeared in the doorway of the building, peering down the lane.

"Who's there?" he demanded suspiciously.

Al Gepper uttered an angry word beneath his breath. It was not to his liking that Pete should be drawn into the affair. However, he could not avoid detection.

"It's Al!" he called softly. "This girl broke up my seance tonight, and I trailed her here. She was prowling around the bell tower."

As he spoke, he dragged Penny toward the Temple entrance. His words convinced her that he had not observed her remove the silken ladder from the belfry wall, nor was he aware that Slippery was a prisoner in the tower.

"Let's have a look at her," said Pete. He flashed a light directly into Penny's face.

"She's the Parker girl--daughter of the publisher," informed Al.

"Yeah," commented Pete. "I saw her at one of our meetings. Another girl was with her. How much has she learned?"

"Enough to get us all run out of town. The question is, what shall we do with her?"

"Bring her inside, and we'll talk it over," said Pete. "Maybe we ought to call a meeting."

"No," replied Al Gepper impatiently, shoving Penny through the doorway.

"We can take care of this ourselves."

The door was locked from the inside. Al pushed Penny into a chair on the front platform.

"Now sit there," he ordered. "One peep out of you and we'll tie you up and tape your mouth. Understand?"

"_Oui, oui, Monsieur_," said Penny, mockingly.
