throw it up. To his surprise, the man did not move. Their
faces almost touched.

"What the devil do you want?" Arnold exclaimed, gripping him by the
arm.

The man did not flinch. He inclined his head towards the interior of
the room.

"Rosario, the Jew," he answered thickly. "He is in the house there.
Will you take him a message?"

"Ring at the door and bring it yourself," Arnold retorted.

The man laughed contemptuously. He stared at Arnold for a moment and
seemed to realize for the first time that he was a stranger.

"You are a fool to meddle in things you know nothing of!" he
muttered.

"I know you've no right where you are," said Arnold, "and I shall
keep you until some one comes."

The intruder made a sudden dive, freeing himself with an
extraordinary turn of the wrist. Arnold caught a glimpse of his face
as he slunk away. While he hesitated whether to follow him, he heard
the door open and the soft rustle of a woman's skirts.

"What are you doing out there, Mr. Chetwode?"

He turned around. Mrs. Weatherley was standing just behind him,

Her hand shot to her side.

"Go on," she whispered.

"I saw his face," Arnold continued. "It was pressed close to the
window. It was as though he meant to enter. I threw the curtains
back, opened the window, and gripped him by the arm. I asked him
what he wanted."

She sat down in a chair and began to tremble.

"He said he wanted Rosario, the Jew," Arnold went on. "Then, when he
found that I was a stranger, he got away. I don't know how he
managed it, for my fingers are strong enough, but he wrenched
himself free somehow."

"Look out once more," she implored. "See if he is anywhere around. I
will speak to him."

He stood at the window and looked in every direction.

"There is no one in sight," he declared. "I will go to the corner of
the street, if you like."

She shook her head.
