“There’s a bare chance, of course. But you want to make pretty sure before you turn a man in as a person missing and for whom a reward is offered. False arrest or detention is rather a serious charge, you know.”

“Yes, I know; that is, I suppose it is.”

Dispirited, Arden looked down at her dusty oxfords. Another of her cherished plans had fallen through. She took a long breath and, looking at the chief again, remarked:

“Well, thank you—very much. I must get back to class now.” She turned to leave.

“Just a moment!” called the chief rather sharply. “Why are you so interested in this man?”

“Oh, of course.” Arden smiled disarmingly. “Only just so I might claim the reward if I found him and have our college pool repaired. The swimming pool, you know. It’s broken.”

“Yes?” encouraged the chief.

“Yes. It seemed like a good way to get the money. A friend of mine is awfully disappointed that she can’t swim. I mean she can swim, but with the pool broken she can’t, and so I was trying to help and—and——”

Arden was at the end of her resources. She turned and fled—beat a most undignified retreat as she told herself later. But the chief was not so easily disposed of.

“Just a moment!” he called rather sharply, and came out from behind the desk.
