When the ordeal was over he tottered back to the couch and lay down exhausted; and I gave him a few minutes while I ran through both his statements. Then I was ready to leave.

"Now about your future. I'll keep my word to you. The stolen paper and your keys shall be returned to your father's office as the price of Baron von Ringheim's pardon. I shall see your father and show him what you have written about it all; and you know well enough that no harm will come to you through him as the result. Are you listening?"

A feeble gesture of the hand was his only response.

"You'd better, for your life hangs on your understanding all I say and doing what I tell you. Your admission of the murder I shall keep a dead secret"--he started at that, raised himself on his elbow and looked across at me--"on one condition. You must be out of the country within twenty-four hours. If I find you here at the end of that time I shall hand it to the police."

With a deep breath of relief he sank back. "I'll go; but I've--I've no money."

"I'll find you enough to get away with"; and I laid a sum on the table; "and as soon as you are across the frontier you can communicate with your friends."

The a.s.surance that he was to have a chance to save his worthless skin had a surprisingly invigorating effect upon him. Now that the suspense was over and he knew the worst which could befall him, he was greatly relieved. He got up and lighted a cigarette. "Don't go yet," he said.

I was at the door and turned.

"I've made an awful mess of things," he went on.

"I don't want to discuss the ethics of your conduct," I retorted.

"I'll go straight now. I'll prove it to you in a minute. But I want you to know that I didn't go to Ziegler's with any intention of killing him.

I went to get off that marriage with the daughter; and it was only when we quarrelled and he made me mad that I did it. He threatened me."

"Anyhow you had arranged that some one else should do it, because you had secretly accused him of treachery to his a.s.sociates. And there isn't much difference between the two."

"How the devil do you get to know so much? Yes, I did that. I'll admit it to you after all this. But I'll go straight, as I said. And here's the proof, so far as you are concerned. The police are still round your house, and if you were to go back without a sign from me you'd all be arrested."

I had not thought of that. "You'd better give me something then."

He went again to the desk and wrote a line or two. "You are to withdraw your men. Hugo von Felsen," I read when he handed it to me.

"Perhaps that will convince you that I am in earnest," he said. "Give it to the fellow in charge there. I shall leave for Austria to-night"; and with that we parted.

On my way home I found myself speculating whether he had been sincere in that last act of his, or whether he could possibly have some other kind of motive at the back of his head. It was uncommonly like a Greek gift.

And then a possible solution occurred to me. My arrest at that moment with the papers I was carrying would have betrayed everything. He had had wit enough to remember that, although I had overlooked it. That sudden return to comparative self-possession took a fresh light in this connexion.

Could he, even now, when I had possession of such d.a.m.ning proofs of his guilt in both affairs, be contemplating some further treachery? Would he dare such a step? He had been reduced to the lowest depths of abject terror when I had confronted him with the proofs and extracted the confessions from him, that it was difficult to credit it was all shamming.

What could he do? His life lay in the hollow of my hand, and he knew me well enough to be certain that at the first glimpse of a trick I should act.

But he was such a slippery devil I could not be sure; and a dozen suggestions flashed into my thoughts. Had that parade of his about the police surrounding the house been no more than a bluff? There were men there, because I had taken care to see them for myself. But were they really the police?

If it had been no more than a lie, it had at any rate resulted disastrously for him. That was a consolation, anyway. But if they were only his creatures and not police, why had he given me the letter to order them to withdraw?

He might be afraid of the papers falling into their hands, of course, and so const.i.tuting a source of practically inexhaustible blackmail for them. But, on the other hand, he might be just laying a trap for me to fall into their hands.

Whatever view I took of it, I should have to be on the alert; and when I reached the house I kept my hand on the revolver which had already done me such service that night.

The men were still there, and as I approached one of them stopped me.

He was dressed in the uniform of the police, but he lacked the military bearing of that remarkably fine set of men.

"I am from Herr von Felsen, and have this note for one of you," I said as I drew it out.

We went to a lamp close at hand, where another man not in uniform joined us. They read it, put their heads together in a whispered conference, and then favoured me with a searching stare.

"It's right enough," said one of them. "Good-night, sir"; and with that they turned away, spoke to some others who appeared mysteriously from I didn't know where, and all walked away in a body.

I waited until they were out of sight before I let myself into the house; and as I closed the door, my sister and Althea came running downstairs.

"Is that you, Paul?" asked Bessie.

"Yes. Everything is as well as we could wish."

Althea laid both her hands in mine. "It has been like a nightmare," she said.

"Von Felsen thought so too, I can a.s.sure you. But with a little luck now a few hours will see all righted. Get ready to start, Bess. You must go right through to Brussels. Sew these papers into your dress; or hide them in any way you like, so long as you get them through safely."

"I shall be ready in a few minutes"; and she ran off with the packet.

"Tell me how you have managed it, Paul. It seems like a miracle," said Althea.

I put my arm about her. "I found out things that beat him, and you will have no more trouble through him."

"What things?"

"Ah, there you must have patience. I am pledged not to speak for twenty-tour hours, in order to give him time to leave the country."

"He will not go," she answered instantly, shaking her head vigorously.

"He dare not stay. If you love me, nothing now can come between us."

"If? Paul!" and she put her arms round my neck; and what followed concerned n.o.body but ourselves. But when she drew away it was to shake her head doubtingly. "I do not trust him."

"Him? No; but his fear, yes. I tell you he dare not play me false."

"Pray Heaven it will all be right; but I still fear for you, Paul."

"It will be as surely as I kiss you now," I whispered. "And now can you get your father to leave? There is no absolute need now, thank Heaven; but while I am doing what I have to do, it would be best for him to be out of the city."

"And you?" she asked with quick solicitude.

"I shall be all right. I hold all the winning cards, whatever happens."

Her dear face clouded and her brows puckered with a frown as she shook her head. "I could not go if you were to remain. I will not, at least until I know that all is right with you. Nor indeed could I if I would.

My father has been in a terrible state for some hours. I told him what you suggested--that the scheme had failed, you know--and he wanted to rush out of the house on the instant. I only stopped him by pointing out the police to him."

"They are gone, I am glad to say. Von Felsen himself gave me a note calling them away. What's that?" I broke off, as a sound upstairs reached us, followed a moment afterwards by the shutting of a door.
