Nan gave a funny little hysterical laugh at this, and the laugh helped to steady her after the shock she had had at the unexpected reappearance of the two men.
"I don't want you to wring anybody's neck," she said, as they passed through another big door and stopped before an elevator. "Only please, Walter," she looked up at him appealingly, "watch out for them and let me know if you see them again. They are following us."
Walter's bewilderment was beginning to change to alarm, and he would have demanded to know all about the strange affair at once, had not the three girls come up to them at that minute.
On the ride up to the third floor of the hotel, where the room engaged for Nan and Bess was located, Grace reminded Nan of nothing so much as a human interrogation mark.
She fairly besieged the girl from Tillbury with questions, which would have been very embarrassing to poor Nan had not Rhoda interposed in her behalf.
"I don't suppose Nan wants to tell us about it now, Grace," she said. "Let's wait till we get upstairs."
Whereupon Grace was silenced temporarily. As for Bess, she was nearly as disturbed as her chum, and the journey up to the third floor seemed interminable.
They reached it, however, and the girls stepped out into a handsome corridor and were preceded by the velvet-footed bellboy past interminable closed doors, to be stopped finally before one particular door, closed like the rest, but evidently belonging, for the space of a day and night at least, to Nan and Bess.
Walter dismissed the boy with a tip, and, drawing a long key from his pocket, inserted it in the door. A moment more and they had stepped into a beautiful room, all blue and gold, and with deep, lacily curtained windows and twin beds set over in one corner, with a small table and a reading lamp beside each one.
