ed the
remainder of the way."

Accordingly they alighted, and the driver was instructed to wait where
he was. Then they proceeded toward Duncan Street, reaching which they
turned into it, and soon were in the neighborhood of No. 620. They
paused in the shadows in which Bat Scanlon had spoken to the old
resident; the house opposite seemed dark and silent.

"No one stirring," said Bat. "This whole section can be as quiet a place
as I know of when it takes the notion."

Ashton-Kirk, who had been straining his eyes through the darkness, now
placed his fingers to his lips and gave a peculiar whistle. After a
moment there was an answer to this, and then a figure emerged from the
shadow of the Burton house. In a very little while longer Fuller crossed
the street to them.

"What news?" asked the investigator, briefly.

"Fenton is in the house," answered Fuller. "I followed him from the
train; he went to the front door, rang in the regular way and was
admitted by what looked to me to be a nurse."

"Had he any idea he was followed?"

"I think not. He made no show of it, anyhow."

"Suppose you stay here and keep Mr. Quigley company for a few minutes,"
suggested Ashton-Kirk. "We'd like to look around a bit."

"I am not accustomed to the night air," complained the broker. "It has a
bad effect upon my breathing."

"We shall be only a very little while," he was assured.

Ashton-Kirk crossed the street with Nora and Scanlon at his side.
Quietly they entered at the little iron gate and stood for a space
examining the house.

From the fan light above the front door came a dull glow, as though a
subdued light burned in the hall.

"All the shutters are closed," said Bat, as he noticed this fact. "They
may be brightly lighted inside and we not know it."

The keen, searching eyes of Ashton-Kirk caught a sort of glow upon the
grass at one side; he moved in that direction and the others followed
him. At the second floor a light flickered dimly in a window; it was a
wavering, uncertain sort of thing, and Bat Scanlon recognized it at
once.

"It's candle-light," said he. "Remember, I told you about seeing the
girl----"

Here he felt Nora's cold hand close upon his wrist; at the window
appeared the figure of Mary Burton, in the same loose gown as before and
holding a candle in her hand. The light was full upon her face as she
bent forward as though intent upon catching some sound. And the face was
white and rigid with fear.
