“Well, then—I don’t see——” The amateur sleuth paused, temporarily at a loss. “It couldn’t have been somebody in the street car, coming out, Edina? A pickpocket, you know. I’ve heard they are very quick with their hands.”

“There ain’t none of ’em quick enough to have got this pocketbook away from me,” Edina retorted grimly. “Anyway, I was holdin’ my hand over the top of it all the way—just for fear someone would get a hold of it.”

Billie jumped to her feet. Her eyes were bright and her cheeks were almost feverishly flushed.

“Then if you are quite sure of this, the money must be up at Three Towers. You have dropped the money out of your pocketbook—perhaps when you picked it up.”

Edina started to say that she could not possibly have done any such thing; but Billie was beyond listening to her.

“Come along,” she cried, with feverish impatience. “We’ve got to get back right away—before any one finds that packet and makes off with it!”

Billie’s impatience infected Edina. The two girls rushed for the street car, caught it by the barest margin, and sat twiddling their fingers in desperate suspense during the seemingly interminable ride back to Three Towers Hall.

Released by the trolley, they rushed to Edina’s dormitory. As luck would have it, the long room was empty and they at once began a feverish search of everything in it, beginning with Edina’s trunk and winding up by peering under mattresses and into pillow slips.

“Nothing!” panted Billie. She sat down on the edge of Edina’s bed to rest “Edina! Edina! Where has that money gone?”

“I’d just about give ten years of my life to know,” returned Edina.
