life or career for a
young man to follow. The adventures of the worker in the cities are
a little grayer, perhaps, than those which come to the man who is
born a wanderer, but they lead home just as surely--perhaps more
safely. Au revoir!"

He turned away abruptly. The door was softly closed. Arnold went
down the steps and set his face citywards.

CHAPTER XXXII

ISAAC IN HIDING

Arnold, as he neared the end of his journey, felt, indeed, that he
had found his way into some alien world. The streets through which,
after many directions, he had passed, had all been strange to him,
strange not only because of their narrowness, their poverty, their
ill flavor, but on account, also, of the foreign names above the
shops, the street cries, and the dark, unfamiliar aspects of the
people. After losing his way more than once, he discovered at last a

There were no visible numbers, but counting the houses on the

The light was as suddenly turned off. Arnold could see now that the
man whom he had come to visit had barricaded himself behind an
upturned table in a distant corner of the room.

"I want a word or two with you, Isaac," Arnold said.

"Who told you where to find me?"

"Count Sabatini."

"Have you told any one else?"

"No!"

"Are you alone?"

"Absolutely."

Isaac came slowly out into the room. His appearance, if possible,
was a little more ghastly even than when Arnold had seen him last.
He was unshaven, and his eyes shone with the furtiveness of some
hunted animal. In his hand he was holding a murderous-looking
pistol.

"Say what you want--be quick--and get away," Isaa
