“Come, girls, get together!” The chaperon was herding them toward the door leading to the waiting cabs. “Tell the driver to take you to Thirty-third Street tube station and there take a train for Hoboken. When you get there, ask at the information desk which is the next train for Cedar Ridge, and don’t forget to sign in as soon as you get back. That is important. We shall have to separate from now on.”

So far so good. Terry and Arden guiltily got into a gaudy taxi with three other girls. The two were thinking so much about Sim; wondering if, should they go on thinking, some subconscious influence would not cause someone to ask about her. The only thing to do was to talk to the other girls about the dance to keep their thoughts occupied with that subject.

“Did they make any money, do you know?” Arden asked a strange girl, one of the three riding with her and Terry.

“They cleared expenses, but I heard they only have a few dollars over.”

“It was a nice party, anyhow,” Terry put in, looking anxiously out of the window. “The music was grand!”

And that ended the half-hearted attempt at conversation. Both Arden and Terry had too much on their minds to do much talking. The other girls were intimately whispering among themselves. They seemed to give no thought to the missing Sim, nor to the fact that Arden and Terry had been two of a trio, inseparable, but were now only a duet.

Their problem was a difficult one.

Where was Sim?

If she was not waiting at the tube station or in Hoboken, what should they do? How could they get back to Cedar Ridge without Mrs. Malvern or someone with inquisitive authority finding out about the missing girl?

Arden privately decided, if they did not find Sim at either station, to tell Mrs. Malvern at the first opportunity.
