His eyes swept it desperately from top to bottom. And as he looked at it, two pink fingers of flame curled out from underneath it. The floor of the room was already taking fire.
But those little jagged fangs of flame meant that there was a small space between the bottom of the door and the floor boards. If he could only push the key through so that it fell on the floor inside he might be able to fish it out through the gap under the door. He whipped out his penknife and probed at the keyhole.
At the first attempt the blade slipped right through the hole without encountering any resistance. The Saint bent down and brought his eye close to the aperture. There was enough firelight inside the room for him to be able to see the whole outline of the keyhole. And there was no key in it.
For one dizzy second his brain whirled. And then his lips thinned out, and a red glint came into his eyes that owed nothing to the reflections of the fire.
Again he fought his way incredibly through the hellish barrier of flame that shut off the end of the corridor. The charred boards gave ominously under his feet, but he hardly noticed it. He had remembered noticing something through the suffocating murk on the landing. As he beat out his smouldering clothes again he located it — a huge medieval battle-axe suspended from two hooks on the wall at the top of the stairs. He measured the distance and jumped, snatching eagerly. The axe came away, bringing the two hooks with it, and a shower of plaster fell in his face and half blinded him.
That shower of grit probably saved his life. He slumped against the wall, trying to clear his streaming eyes; and that brief setback cheated death for the hundredth time in its long duel with the Saint's guardian angel. For even as he straightened up again with the axe in his hands, about twenty feet of the passage plunged downwards with a heart-stopping crash in a wild swirl of flame, leaving nothing but a gaping chasm through which fire roared up in a fiendish fountain that sent him staggering back before its intolerable heat. The last chance of reaching that locked room was gone.
A great weariness fell on the Saint like a heavy blanket pressing him down. There was nothing more that he could do.
He dropped the battle-axe and stumbled falteringly down the blazing stairs. There was no more battle now to keep him going. It was sheer blind automatism rather than any conscious effort on his part that guided him through another inferno to come reeling out through the front door, an amazing tatterdemalion outcast from the jaws of hell, to fall on his hands and knees on the terrace outside. In a dim faraway manner he was aware of hands raising him; of a remembered voice, low and musical, close to his ear.
"I know you like warm climates, boy, but couldn't you have got along with a trip to Africa?"
He smiled. Between him and Patricia there was no need for the things that other people would have had to say. They spoke their own language. Grimy, dishevelled, with his clothes blackened and singed and his eyes bloodshot and his body smarting from a dozen minor burns, the Saint smiled at her with all his old incomparable impudence.
