“Send all the servants here,” he commanded. “Every one of them, mind you!”

Presently they congregated in the roomy nursery, which had now been brilliantly lighted. There were five women—some old and some young, but all Mexicans—and a little withered Chinaman named Sing Fing, whose age was uncertain and whose yellow face seemed incapable of expression.

Uncle John, assisted at times by Rudolph and Arthur, did the questioning. Marcia had seen Miss Travers leave the house, alone, at about two o’clock, as if for a walk. She did not notice which way the nurse went nor whether she returned. Perhaps she wore a cloak; Marcia could not tell. The day was warm; doubtless Miss Travers had no wraps at all. A hat? Oh, no. She would have noticed a hat.

The only one who recollected seeing Inez was Eulalia, a chambermaid. She had observed Inez sitting in the court, in a despondent attitude, at about half past two. Yes; it might have been a little earlier; it was hard to remember. None of the house servants paid much attention to the nurses. They had their own duties to perform.

But the baby had not been seen at all; not since Inez had brought her in from her ride at noon. Then it was Miss Travers who had taken the child from the cab and with her disappeared into the nursery.

This report did not prove reassuring. Sing Fing announced that Miss Travers had prepared the baby’s liquid food in the kitchen at half past twelve, but that neither she nor Inez had joined the other servants at luncheon. This last was not an unusual occurrence, it seemed, but taken in connection with the other circumstances it impressed the questioners as suspicious.

“Perhaps they are all at the Mexican quarters,” exclaimed Patsy, with sudden inspiration.

Arthur and Rudolph immediately volunteered to investigate the quarters and started off on a run.

“It’s all right, you know,” consolingly panted Dolph, on the way. “The baby and her nurses can’t be lost, strayed or stolen, so don’t worry.”

“Common sense urges me to agree with you,” returned Arthur, “but there’s certainly something mysterious about the disappearance.”
