"But who is he, do you suppose?" Jess Morse demanded, when the three girls left the hospital and walked uptown again. "He can't be any person who has friends in Centerport, or they would look him up."

"That seems to be sure enough," admitted her chum. Then: "Shall we walk along with Janet?"

"Of course," said Jess. "Are you going home, Miss Steele?"

"Yes," said the girl in the Red Cross uniform. "I have been on duty at the Central Chapter; but mother expects me now."

"How is your mother, dear?" asked Laura, with sympathy.

"She is as well as can be expected," said Janet gravely. "If she had nothing to worry her mind she would be better in health," and she sighed.

Janet did not explain what this worry was, and even Jess, blunt-spoken as she often was, could not ask pointblank what serious trouble Mrs. Steele had on her mind.

Again the Central High girls went in to see the invalid upon Janet's invitation. They found Bobby Hargrew there before them. Harum-scarum as Bobby was, nobody could accuse her of lack of sympathy; and she had already learned that her fun and frolic pleased the invalid. Bobby did not mind playing the jester for her friends.

Of course, the strange man at the hospital was the pivot on which the conversation turned.

"Were you there, too, to inquire about him?" asked Mrs. Steele of Janet.
