Now, trembling with excitement, they began to search. There was no stairway on either side up to the low roof, and the beam of the torch, which easily reached it, showed the rugged rock ceiling to be unbroken. A moment later, as the beam swept the dead end of the cave, their hearts gave a bound. In one corner there was a small arched doorway so deeply recessed in the rock that they would never have noticed it had they not been looking for something of the kind. They ran towards it, seized its iron ring handle, turned it back and forth and pulled upon it. But the little door was of thick ancient oak, firmly set into its surround of rock, and locked.
Sabine began to hammer on it with her fists and to shout for help, but Gregory drew her back and tried to quiet her by saying, 'It's no good doing that. Even if people come down here through that door now and then, you can be certain there is no one the other side of it to hear you at this hour.'
But we must get through it! We must!' she cried hysterically. 'We might wander in these caves for days and never get so near escaping. If we don't get out this way we'll die here.'
Gregory knew that she might well prove right, and his own hopes of forcing the door were far from sanguine as he said, 'I'm going to try to blow the lock off. But for goodness sake don't count your chickens. A lock like this is a very different proposition to the flimsy sort of thing usual in modern flats, and I doubt if I'll be able to.'
From the ancient aspect of the door, he felt certain that its lock would be one of those great iron contraptions made in the middle ages; but as it was set in the wood on the far side of the door he could not even see it, or tell the position of its keyhole. His automatic was only a light one; so if the oak was more than a few inches thick the bullets might embed themselves in it without even reaching the lock and wrecking it so that its tongue could be pushed back.
After a moment he decided that the only chance lay in attempting to blow away a piece of the stone socket into which the tongue of the lock fitted. But that was going to be a tricky and dangerous operation; for the bullets would not bury themselves in the stone but ricochet off it and they, or bits of flying rock, might do him serious injury.
Handing the torch to Sabine he emptied the canvas bag of its contents; then, holding the small automatic in his right hand, he put both inside it, wrapped it round them and with his left hand held the loose ends together over his wrist. The leather bottom of the bag and thick canvas now twisted in a wedge round his fist might, he hoped, be just enough protection to stop a small bullet smashing the bones of his hand should it ricochet back on to it. Having placed Sabine where she could shine the torch on to the tongue of the lock without being in the line of danger, he held the pistol close to it and fired three times through the canvas.
There came three spurts of flame and ear-splitting reports in quick succession. As the wisp of smoke cleared they peered eagerly forward. The trick had worked. A big splinter of stone two inches thick in the middle and eight inches long had been smashed off by the bullets on the far side of the tongue of the lock. One push and the heavy door swung open.
It gave on to a narrow flight of stone steps. Without pausing to collect the oddments scattered on the floor, they ran up them and found themselves in a low vaulted chamber. At one end of it there was an altar on which burned a small lamp. With hands outstretched Sabine staggered forward, threw herself on her knees before it and began to babble incoherently.
Gregory's ideas upon religion were by no means as orthodox as hers; but he was very far from being an agnostic and, although more slowly, he too went on his knees to render thanks for a merciful deliverance.
A few minutes later she was asserting her conviction that it was having devoted one of their precious candles to the Holy Mother, at the altar down in the cavern, which had caused Her to save them, and insisting that he should get the other candles in order that they too could be lit to Her glory; so he went down to fetch them.
On his return he found that Sabine had disappeared, and he was wondering a little anxiously where she could have got to when she emerged from the shadows at the far end of the crypt. She had just explored another stairway that led upward from it, to see if she could identify the church they were in, and had recognized it at once as the great Coronation Church on the top of Buda hill.
When he remarked that in that case he was surprised that the crypt was not larger, she said that it was not the main crypt and was probably part of a much older building. They decided that the cigarette butt they had found must have been left by some visitor who had been shown the entrance to the caves by a custodian, and had decided to light up there for a few quick puffs before coming back into the church.
While Sabine was lighting the remaining candles, Gregory looked _at his watch and saw that it was just on five o'clock; so their ordeal in the caves had lasted over four hours. When she had done she said another prayer then, as she got up, turned to him with a smile:
'That's better! A quarter of an hour ago I was half dead from fatigue and terror. Now, I'm feeling a new woman. I wish I hadn't had to leave my jewels behind, and had a few more clothes on; but fortunately we have plenty of money.'
'Yes,' he agreed soberly. 'That's the one thing in our favour; and it may prove the means of our getting away in the long run. But I'm afraid you'll have to wait for a bit before you think of using any of it to buy more clothes.'
She frowned. 'Of course, it's Sunday morning, isn't it? For the moment I'd forgotten that.'
'Even if it were eleven o'clock on Monday you still wouldn't be able to go shopping.'
'Why not at some little place where I wasn't known?'
For hours he had been seeing her only in semidarkness; but now he was looking at her in the full light of six candles. He had known that she must have got dirty and untidy but he had been far from realizing her true state. Her face and hands were still blackened with smoke, her eyes were bloodshot and red rimmed, her hair was matted, her stockings were torn and her shoes were cut almost to ribbons. Apart from the fact that she was wearing a beautiful sable coat, she looked a veritable tramp.
He guessed that he must look equally grubby and villainous, as he said, 'Take a good look at me; then you can judge what you look like yourself. If you went into any shop as you are they'd immediately jump to the conclusion that you had just stolen those sables.'
'Perhaps it's as well it is Sunday, then.' She gave a quick shrug. 'Anyway, my coat is covering enough for decency; and it will serve until we are safely out of Budapest.'
Gregory sighed. 'You're taking it for granted that we will be able to get out. Don't you see that as far as our appearance goes there would be no difference between a clothes shop and a garage. At the moment we look like a gangster and his moll who have just fought their way out of a shindy in some low night dive and my filthy dinner jacket helps to create the picture. If we go anywhere in our present state and I produce a wad of money in an attempt to buy or hire a car, the people will think that we are a pair of thieves trying to make a getaway. They'll make some excuse to detain us then telephone the police.' He paused a second, then added unhappily:
'And that's not the worst. You've been wonderful, and I hate to have to say this, but it would be stupid to conceal from you what we are up against. Looking as we do, and with you in that ten thousand dollar coat, from the moment we step into the street we'll be liable to arrest on suspicion.'
