Margie moved on, for the sake of silence scraping the walls as little as possible. She traversed what was left of the upper passage and then went down the long, steep stairs, using her light. When at last she reached the peephole giving a view of the great hall, nothing had changed. The great logs still crackled in the enormous fireplace, the pig or whatever it was continued roasting. The aroma made Margie hungry. In her shoulder bag were a couple of candy bars that she meant to eat later. Anyway she certainly wasn’t just going to camp in this spot waiting for Simon to appear. He’d need an hour, at the very least, to get back across the river and then drive round, by way of the bridge at Blackhawk, to approach the castle by road in the manner of an ordinary guest.
Using her flashlight sparingly, keeping its beam aimed low, Margie went on down, following the tunnel underground. A minute more, and she had passed the branching way—without giving it much thought—and was back in the cave, peering out into the now-gloomy daylight of the deserted grotto and its paved forecourt with the statues and the curious stone table. The fact that a cloud had come over the sun made the whole place now look somehow ominous. But, reassuringly, it was as quiet and uninhabited as ever. The jail-door was closed and bound with the chain and lock—Simon on going out must have been careful to leave it exactly as before, which was only what you would expect from someone as meticulously professional about details as he was. Now Margie ought to be able to do the same thing with the gate, and just slip out for a minute into these deserted woods…
It took a little more than a minute, maybe two or three. Then she was back inside the cave again, physically relieved and ready to concentrate properly on the job at hand. She carefully bound up the chain and lock just as before, and retreated into the underground portion of the passage. The next step, she had decided, would be to get a little rest. She would find a relatively dustfree place and stretch out, maybe catch a little nap. Margie knew her own habits; the danger that she was going to oversleep was just about zero.
Within a few minutes Margie was dozing on the tunnel floor, shoulder bag serving as a pillow. When she awoke it was with a start, and the feeling of having been asleep for some time. At first she had no faintest idea of where she was or how she’d got here.
Memory returned, bringing with it reassurance of a sort. The gloom in the tunnel was much thicker than it had been when Margie dozed off; darkness had obviously fallen outside. She had a bad moment, wondering if after all she could have overslept. But no, her watch showed it to be only a little before seven. Some shadow must have come over the inlets for air and light. Perfect timing, she thought, or close to perfect. They had decided dinner probably wouldn’t start till eight, and the show would go on after dinner.
Margie rose without haste and stretched. Then she picked up her bag and hurried along to the agreed-upon primary rendezvous, the peephole giving into the great hall. She braced herself in a standing position at the lookout, watching and waiting for Simon to appear.
Her wait was short, so short that she again sent up a silent cheer for perfect timing. Here came Simon from another room, alone, wearing his swim trunks now and carrying still-dry towel. The expression on his face told Margie of controlled worry, concern deeper than the usual preperformance tenseness. Maybe, she thought guiltily, Si had been here at the rendezvous before, trying to signal her about some problem.
He gave the primary signal now, brushing at his hair, and Margie felt another twinge of guilt to see his relief when she answered at once with the flashlight, signaling that she was in place and everything was fine. And then Margie could feel relieved, for Si signaled to her nothing about difficulty or cancellation; he only paused for a moment, looking up at something above Margie’s head and out of her range of vision, and then he walked on out of the great hall, doubtless to have his swim. She thought it must be something other than the performance itself that was worrying him. Maybe he’d been told that the fee wasn’t going to be a full thousand after all.
Anyway she could now relax again for a little while. Things were rolling, the act could go smoothly, just the way they wanted it. They might even pull off a really spectacular effect. Margie could imagine how it would be for the audience, a roomful of people absolutely certain that they were facing solid stone walls, when a voice spoke to them out of nowhere, and then in response to a magician’s gesture the figure of a young woman took shape out of thin air…
It wasn’t too early now for her to get her costume on. She slipped it out of the handbag and inspected it as well as she could in the poor light. Diaphanous was the word. She had debated with herself about how much to wear underneath it, and was glad now that she’d decided a full leotard wasn’t too much. She had the leotard on now under her shirt and jeans, and a good thing too, if that fat man she’d just been spying on upstairs was going to be in the audience, as he undoubtedly was. Something about him made Margie shudder inwardly, and she hadn’t even seen his face.
She exchanged her white gym shoes for black ballet slippers for the performance; not that it was unlikely that anyone would be studying her feet very closely.
She had just finished changing, except for her shoes, and had got the street clothing crammed into the handbag, when new distraction came, in the form of what sounded like a groan. It was a faint sound, yet gave the impression of coming from somewhere uncomfortably close. There couldn’t, thought Margie, there absolutely couldn’t be anyone else in this unknown passage with her. And yet it certainly sounded like it.
Another faint groan wavered in the air, again too close for comfort, too close to be ignored. Was Margie herself now to be the target for some kind of trick?
That was one of the first thoughts that leapt into her mind. She had to know. Penlight in hand, Margie prowled the tunnel. Not that way, this way. The moaning sound obligingly repeated at irregular short intervals. She was led to the branch passage going down, but paused at its top step. She had assumed, when Simon ignored the branch, that he knew where it led and that it could be disregarded.
Now that she looked carefully, she could see one set of footprints in the dust of the stairs before her. It was hard to tell if the faint prints were going up or down.
She sat her shoulder bag down carefully on the floor, leaving herself freer for quick action, and tiptoed down the stairs, stepping in the tracks. She came to a thick wooden door, standing slightly open. The groans emanating from its other side. When she snapped off her tiny flashlight she could see faint torchlight flickering through the opening around the door.
Margie stood still, thinking. She didn’t need to think for very long. Groans and an open door, whatever else they might mean, indicated that other people besides herself and Simon had to be aware of the supposedly secret passage. They meant, at the very least, that the whole elaborately planned trick had to be considered blown. They meant—
She had to find out what they meant. It was impossible to do anything else until she knew.
The door swung back easily, with only the faintest squeaking of its antique-looking hinges. What lay beyond it resolved no questions for Margie, but only raised them to a new level.
In her short life she had seen a lot of acts, good ones and bad ones, from inside and out. She could tell at first glance that the semiconscious old man bound to the torture rack was no willing participant of any act. His arms and legs were almost plump, his ribs scrawny. His head, shaggy with gray hair and beard, rolled slowly from side to side. His eyes were closed. His mouth, open to reveal bad teeth, drooled a little from one corner.
