passed the corner! Well,
well, strange--isn't it?"

With another glance down the street, a whimsical lift of his shoulders,
he headed west into the dilapidated tenement quarter that huddled for
a handful of blocks near by, just south of Washington Square. It was
a little after one o'clock in the morning now and the pedestrians were
casual. Jimmie Dale read the street signs on the corners as he went
along, turned abruptly into an intersecting street, counted the
tenements from the corner as he passed, and--for the eye of any one who
might be watching--opened the street door of one of them quite as though
he were accustomed and had a perfect right to do so, and went inside.

It was murky and dark within; hot, unhealthy, with lingering smells of
garlic and stale cooking. He groped for the stairs and started up.
He climbed one flight, then another--and one more to the top. Here,
treading softly, he made an examination of the landing with a view,
evidently, to obtaining an idea of the location and the number of doors
that opened off from it.

His selection fell on the third door from the head of the stairs--there
were four all told, two apartments of two rooms each. He paused for an

arms, sprang with a startled cry to his feet.

"Good-morning," said Jimmie Dale again. "Your name's Hagan, Bert
Hagan--isn't it? And you work for Isaac Brolsky in the secondhand shop
over on West Broadway--don't you?"

The boy's lips quivered, and the gaunt, hollow, half-starved face,
white, ashen-white now, was pitiful.

"I--I guess you got me," he faltered "I--I suppose you're a
plain-clothes man, though I never knew dicks wore masks."

"They don't generally," said Jimmie Dale coolly. "It's a fad of
mine--Bert Hagan."

The lad, hanging to the table, turned his head away for a moment--and
there was silence.

Presently Hagan spoke again. "I'll go," he said nu
