n."

"What station?"

"They didn't say. But they spoke of taking a car to 42nd Street, and
crossing over. It must have been the Grand Central."

"Or possibly the West Shore. We'll have to try both. Are you able to
leave now?"

Grace straightened out her stiffened limbs.

"Yes--I--guess so."

"Then come along."

As they started to leave the place, two men confronted them at the door.
One was Mr. Scully, he of the ground-floor apartment, the other a short,
thickset man, who at once announced himself as the janitor of the
building.

"What's going on up here?" he questioned. "I heard a shot."

Duvall pointed to the crumpled heap on the floor.

"I had to shoot it, though I'm sorry now that I did. It attacked me in
the dark. I couldn't afford to take any chances. My wife was locked in
here, and was, so far as I knew, in grave danger."

"Your wife?" The man glanced at Grace.

"Yes."

"But--where is Miss Norman? And how did that monkey get in here?"

"Miss Norman left here some time ago. Another woman, by the name of
Ford, was with her. She brought the monkey."

"What for?"

"I imagine she didn't want to leave it at her rooms. She did not expect
to return there."

"And Miss Norman's gone, you say?"

"Yes."

"Where to?"

"I don't just know, but I mean to find out at once. She has been guilty
of a grave offense, on account of which I have been trying to lay my
hands on her for several days. My wife tells me she took most of her
belongings with her in her flight."

"Flight, eh?" the man growled. "And she owes us a month's rent. I hope
you find her."

"I think I shall. Meanwhile, suppose you wait here in the apartment, in
case, for any reason, she comes back. If I find her I shall bring her
here at once, and unless the place is open I couldn't very well get in."

"All right." The man glanced about the disordered room. "That damned
monkey has smashed a lamp and a lot of ornaments that somebody's got to
pay for. Miss Norman rented this place furnished."

Duvall made no reply, but nodding to Grace, led the way to the hall.

"I'll be back soon, whether I find the woman or not," he said. "I've got
some investigations to make here."

Accompanied by Grace, he descended to the cab. Leary seemed overjoyed to
realize that Grace was safe, and began a long apology for his
carelessness in not waiting for her earlier in the evening, but Duvall
cut him short.

"Good thing you didn't," he said. "By coming back
