Through this silence our feet echoed along the bare floor of the upper hall, as well lighted as belowstairs and as dismantled, to the door of the day nursery. The door was locked—double locked, in fact. For the key had been turned in the old-fashioned lock, and in addition an ordinary bolt had been newly fastened on the outside of the door. On the outside! Was that to keep me in? It was certainly not to keep anyone or anything out. The feeblest touch moved the bolt.

We were all three outside the door. We seemed to keep our compactness by common consent. No one of us left the group willingly; or, leaving it, we slid back again quickly. That was my impression, at least. But the bolt rather alarmed me.

“This is your room,” Mrs. Reed said. “It is generally the day nursery, but we have put a bed and some other things in it. I hope you will be comfortable.”

I touched the bolt with my finger and smiled into Mr. Reed’s eyes.

“I hope I am not to be fastened in!” I said.

He looked back squarely enough, but somehow I knew he lied.

“Certainly not,” he replied, and opened the door.

If there had been mystery outside, and bareness, the nursery was charming—a corner room with many windows, hung with the simplest of nursery papers and full of glass-doored closets filled with orderly rows of toys. In one corner a small single bed had been added without spoiling the room. The window sills were full of flowering plants. There was a bowl of goldfish on a stand, and a tiny dwarf parrot in a cage was covered against the night air by a bright afghan. A white-tiled bathroom connected with this room and also with the night nursery beyond.

Mr. Reed did not come in. I had an uneasy feeling, however, that he was just beyond the door. The children were not asleep. Mrs. Reed left me to let me put on my uniform. When she came back her face was troubled.

“They are not sleeping well,” she complained. “I suppose it comes from having no exercise. They are always excited.”

“I’ll take their temperatures,” I said. “Sometimes a tepid bath and a cup of hot milk will make them sleep.”

The two little boys were wide awake. They sat up to look at me and both spoke at once.

“Can you tell fairy tales out of your head?”

“Did you see Chang?”

They were small, sleek-headed, fair-skinned youngsters, adorably clean and rumpled.

“Chang is their dog, a Pekinese,” explained the mother. “He has been lost for several days.”

“But he isn’t lost, Mother. I can hear him crying every now and then. You’ll look again, Mother, won’t you?”

“We heard him through the furnace pipe,” shrilled the smaller of the two. “You said you would look.”
