"It was after you left him this afternoon. Something you said made him speak to me. He had had a letter threatening his life, and charging him with treachery; and I was threatened also."

I had been kneeling all this time by the body and now rose. "You have no idea who can have done this?"

"None. He told me he had an important interview to-night, and must not be disturbed. That was why I did not come down earlier."

"We must find out with whom," I replied. "And now we must have the police. Have you nerve enough to fetch them or shall we go together?"

"Don't leave me."

At that instant as we turned to leave, I heard a sound somewhere in the house. Hagar heard it also, and clutched my arm shaking like a leaf.

"You say we are alone in the house?" I asked in a low tone.

She nodded, her eyes strained in the direction of the sound.

We stood listening intently.

"They have come back in search of me," she whispered.

"Then we shall find out who they are. Courage."

I glanced round the room and motioned to her to hide behind the curtains which covered the deep window recess, and stood there with her.

Two or three minutes of tense silence followed. Then we heard footsteps stealthily approaching the room. A pause, and then three men entered.

One a grey-haired, distinguished-looking man well on in years; the other two younger and of a commoner type, swarthy, determined-looking men.

From where they stood they could not see the body of the Jew, and judging by their start at finding the room empty, I judged that they had expected to see Ziegler at his desk.

Their words confirmed this.

"Not here, the old fox," growled one.

"Come away. Come away," said the elder man, laying his hand nervously on the arm of one of the others.

"Not till this thing is settled," he replied, shaking off the other's hand impatiently. "I mean to have the truth out of the old rat, or his life."

"And the girl's too," added the other. "You know what we were told about them both. I shall wait for him."

"No, no. No bloodshed, no bloodshed, for Heaven's sake," cried the old man with a gesture of protest and dismay.

"My G.o.d! Look here!" This was from one of the two who had moved forward and was pointing at the dead body.

The old man gave a cry of horror and sank into a chair covering his face in his clasped hands.

"What can this mean?"

His companions were standing by the body gazing at one another in blank wonderment and surprise. Then one of them stooped down and examined the corpse.

"Dead, sure enough; and murdered, too," he announced.

He rose and they both looked round at the elder man. "Do you know anything of this?" asked one.

Without a word the man they addressed sprang up and rushed out of the room.

The two stared at one another again in silence.

Then one of them laughed sneeringly.

His companion winced. His nerves were not so tough.

"What shall we do?" he asked rather huskily. He was beginning to shake.

"Do? Why, what we came to do, of course. Find the old rat's daughter and finish the thing," he said brutally, and with an oath.

Hagar was trembling like an aspen and her breath was so laboured and heavy that I made sure they would hear it.

I pressed her arm to try and rea.s.sure her.

"I think we'd better go," said the weaker fellow.

A muttered oath at his cowardice was the response. "I'm going to search the house," declared his companion, and he began to glance round the room.

But the other went toward the door. "I'm going."

At this moment Hagar could restrain her terror no longer, and a heavy half-sigh half-groan burst from her.

Both men turned at once toward the curtains, and the bolder one put his hand to draw a weapon, knife or pistol; but before he could get it out, I stepped forward and covered him with my revolver.

"The Englishman!" they both cried in a breath, and the man by the door darted out of the room.

His companion stood his ground and met my look steadily.

"So it's your work, eh?"

"Take your hand from that weapon of yours," I cried sternly.

"What quarrel have you with me?"

"Do as I say," I thundered.

He took his hand from his pocket, shrugged his shoulders, and deliberately turned his back on me and walked toward the door.

His consummate coolness placed me in a dilemma. Shoot him down in cold blood I could not.

Hagar's courage returned the instant she perceived that the advantage was on my side. "Don't let him go," she said, and stepped forward.

The fellow started at the sound of her voice and looked at her with an expression of the bitterest malignity.

"Stop, you," I cried.
