It was a difficult problem. On the one side there was Althea's happiness and all I cared for in life; on the other, the satisfaction of the demands of abstract justice and the punishment of a murderer.

I do not know how another man placed as I was would have acted, but I could not bring myself to make the necessary sacrifice. Let those blame me who will, but let them first try to put themselves in my position.

I resolved to try and use the knowledge I had for my own ends.

There were many difficulties in the way. The deed was not one which I could use to force the hands of von Felsen's friends. It was too heinous. They would not dare to attempt to condone it. What I had sought to obtain was the proof of some act of his which, falling far short of such a crime as this, would drive them to agree to my terms in order to save him from exposure and disgrace.

But I could use the power with von Felsen himself to force him to the commission of such an act; and with this intention I resolved to go straight to him now, using the message from Hagar as the reason for my visit.

I should have to act very warily and use the utmost caution in choosing the moment for showing my power.

I did not find him at his house, and at first this rather surprised me; but I knew the clubs he belonged to, and set off to make a round of them. Then I guessed his object. On such a night he would not dare to be alone; cunning would lead him to do all he could to be able to account for his time, should suspicion ever point in his direction.

I found him at the second effort, and sent in my name, saying that my business was of the greatest importance.

"I must speak to you in private," I told him when he came out with an a.s.sumption of irritation at my interruption of his pleasure. But it was easy to see that under the surface he was intensely wrought and uneasy.

"I don't know what you can want with me," he said, as he led me to a room where we could be alone.

"I have very grave news for you and a message. Herr Ziegler has been murdered to-night, and his daughter wishes you to go to her at once."

He had schooled himself carefully to hear the news when it came.

"Murdered? Old Ziegler? Do you mean that, Heir Bastable?" he exclaimed.

"Certainly. I have just come from there." I kept my eyes on him closely, watching every gesture and expression.

"Good G.o.d!" he cried next, throwing up his hands, as if the significance of the news were just breaking in upon him. He acted well, but could not meet my eyes. "Tell me all about it."

"The police will tell you. They are at the house."

"Of course they would be," he said, keeping his head bent. Then, after a slight pause: "Have they any clue to the thing?"

"Yes. They know who did it."

I spoke very sharply, and the unexpectedness of the reply startled him out of the part he was playing. He glanced up quickly, his face pale and his eyes full of fear. "Whom do they suspect?"

"They do not suspect. They know," I replied, emphasizing the last word.

Alarm robbed him of the power of speech for the instant, "I'm glad to hear that," he said quite huskily. "Who was it?"

"Some of Ziegler's shady political a.s.sociates. They were seen at the house."

His sigh of relief was too deep to escape me; it came straight from his heart. Before he answered he took out his case and lighted a cigarette.

"By Jove, the news has shaken me up; see how my hand trembles." Cool, to draw pointed attention to his own agitation.

"It couldn't shake much more if you had done the thing yourself."

The cigarette dropped from his fingers. "I don't know what the devil you mean. If it's a joke it's a devilish poor one."

"I was only wondering if you could have been more upset if you had done it," I replied, fixing him again with a steady stare.

Whether he had any suspicion of what lay behind the words I do not know, or whether some sense of danger nerved him to make an effort; but his manner underwent a sudden change, and he became callous and cynical. "I suppose you writing fellows affect that sort of experiment. If you can bring yourself down to plain facts perhaps you will give me some account of the affair."

"I should have thought you would be anxious to get to Fraulein Ziegler at once in such a case."

He laughed very unpleasantly. "Not if you knew how that girl bores me."

"You don't mean that you won't go to her?"

"What has it got to do with you?" He was fast recovering his self-composure. Voice and manner were steadier, as the belief strengthened that no suspicion would attach to him.

For a moment I hesitated whether to strike the blow which would bring him to my feet, and my fingers went to the ring in my pocket. But I resolved to wait. "It has nothing to do with me," I answered; "but as you are going to marry her to-morrow, and this blow has come at such a moment, you can understand how she needs the strength of your support."

"You don't suppose there can be any marriage to-morrow, surely! Of course the old man's death has altered everything--made that impossible, I mean."

"It would be like you to desert her at such a time; but she has all her father's papers, you know, and is not exactly the sort of girl to stand any fooling."

"She can do what she pleases, and so shall I," he answered with a shrug and a sneer. "Anyway, she can't be married on the day after such a thing."

I knew what he meant. He was not afraid of Hagar as he had been of her father. There would be no marriage if he could avoid it.

"Well, I have given you her message, and if you don't intend to go to her, it's your affair not mine"; and I turned on my heel.

"You haven't told me how it happened," he said quickly.

I turned for an instant. "You'll hear it all from the police and will get their theory; and perhaps when you do hear it, you'll take my view that they are all wrong. I told them so to-night."

I just caught his quick glance of consternation at this as I swung round and went off. As I was crossing the hall I looked back and saw him standing leaning against the table in moody thought.

I walked home thinking that the cool air would refresh me after the strain of the night's events. I was worn out and sorely in need of sleep.

My sister was waiting for me with a very worried expression in her eyes.

"I began to fear something had happened again, Paul," she said.

"Something has happened, Bess; but I can't talk to-night. I'm as tired out as a hound after a hard day across country. I must get straight to bed."

"You look awfully worried, dear. Eat something; I'm sure you need it."

"You girls always seem to think that if a man can only be got to eat, nothing else matters," I exclaimed fretfully.

"Well, try the prescription now at any rate," she replied with a bright smile. "And while you eat I have something to tell you."

"If it's anything in the shape of another worry keep it till the morning; if it will keep, that is."

"I'm afraid it won't, Paul," she said, with such a rueful air that I could not refrain from smiling.

"Well, I'll take your medicine, if only to please you"; and I sat down to the dainty little meal she had had prepared. "What is it?"
