She lifted the child from his hiding place and stood him upon the floor, then quickly swung the heavy slab of plaster back into position. At least, she reasoned, the kidnappers, when they returned, should not at once learn that their captive had escaped.

She knew that the hiding place had been but a temporary one, a means whereby the child might be kept out of sight during the day in case strangers should happen to enter the room. As soon as the kidnappers returned, they would, she realized, spirit the child away to some more secure retreat.

She went to the door and again shook it frantically, pulling at the knob with all her strength, without producing the slightest result. The lock was evidently a strong one—the door held firm and unyielding, though she threw against it her entire weight.

Evidently there was no hope of escape here. Then she again bethought herself of the window. For a moment she gazed out into the darkness. The pavement was thirty feet below. No one was in sight. How could she ever reach the ground, with the child as well, even if she had possessed a rope? The thing was impossible.

Clearly there was nothing to do but wait. Possibly the assistance she expected from her friends, or the police, would arrive very soon—surely she could in some way keep the kidnappers occupied until then!

And suddenly she realized that the time had come. She heard the door of the house close softly, and upon the stair the sound of mounting footsteps.

Which was it, the police, or the kidnappers? The latter, she felt morally certain, since the former, in their haste to rescue the child, would beyond any question have arrived in an automobile, and at top speed.

The newcomers were mounting the stairs in a leisurely manner, as though free from any anxiety. Grace heard them pause for a moment on the first landing, then start up the second flight of stairs. It seemed to her out of the question, to stand in the middle of the room and await their entrance. At least she could postpone the fatal moment a little while, by hiding, with the boy, in the closet. She stepped into it, the child's hand in hers, and drew the door shut, just as the two men entered the room. On her way, she hastily blew out the candle.

They were the same two men that she had seen before,—the black-bearded man, now without his beard, and the artist, Durand. She saw this, as soon as the latter had relit the candle. She wondered if he would notice that the wick was still warm. Evidently he did not; for they threw themselves into chairs, lit cigarettes, and began to talk.

"Now we can speak freely," said Durand. "How did things go?"
