“No, no; why should I be? They may merely be tired out and have gone to bed or they may need me—I can’t take any chances where they are concerned, my boy.”

“Of course not,” said Kenneth with unusual emphasis. “If you are going to walk over, Doctor, I’d like to go along with you.”

“Take you away from the festivities? Nonsense! The girls in there would never forgive me!”

“Oh! hang the whole business! I beg your pardon, Doctor, I forgot it was your sister’s function.”

The Doctor laughed. “Come along with me. You need ozone to restore your placidity, but go back again later, like an obliging chap, if only to give my message to poor Grémond.”

They had been swinging along for several blocks in the cool night air when Landor broke the silence by exclaiming savagely, “What in thunder has Jules Grémond to do with them!”

“With the Dales?” asked the Doctor innocently, inwardly amused at Landor’s resentful tone. “He met them in California, I believe.”

“Umph!” grunted Kenneth.

“Here we are,” said the Doctor presently as they reached the house, “and there are lights in their rooms, so they are up about something and it is well I came. Goodnight, and thank you for walking over with me, Kenneth.”

“Dr. Ware,” said the younger man wistfully, detaining him a moment on the steps, “if there is anything wrong up there,” with a motion of his head toward the top story, “you’ll let me know, won’t you? And if I could be of the slightest service you’ll call on me without hesitation, won’t you? Of course I know they’ve no possible use for a chap like me but I’d move heaven and earth to do anything—to feel that I was really of service to them in any way.”
