a long wait. After what seemed to Grace an
interminable time, they saw a taxicab come rapidly down the street,
execute a turn, and draw up before the door of number 162.

Grace, as soon as she realized the cab's destination, sprang to the
sidewalk and strolled carelessly along in the direction of the house.
The cab came to a standstill just before she reached it, and two women
got out. One of them Grace had never seen before. The other she
recognized at once. It was the woman who had fainted in the theater the
previous night.

Neither of the women paid any attention to her, but directing the cabman
to wait, passed quickly into the house.

Grace went back to her cab and got in.

"The woman I am looking for has just driven up in that cab," she said.
"She has gone into the house. The cab is to wait. When she comes out
again, follow her." Leary nodded, and the two of them settled down for
what they supposed would be a long wait. To their surprise, scarcely ten

the woman whom Grace had recognized dashed down the steps and sprang

and were now speeding northward again in the neighborhood of 72nd
Street. Then, to Grace's surprise, the cab ahead swerved into a side
street, and drew up before the entrance of the hotel at which Ruth
Morton and her mother were stopping. The cab had no sooner stopped than
the woman sprang out and entered the lobby.

Grace followed her without a moment's hesitation, ordering Leary to
wait. The woman hurried up to the desk and, taking a blank card from it,
scribbled a few words upon it in pencil, and handed it to the clerk.
Grace was unable to hear what she said to him, but the man nodded, and
handed the card to a bellboy. The woman sat down in a nearby chair.

Grace, having nothing else to do, and being somewhat afraid that the
woman might recognize her, crossed at once to the opposite side of t
