"The spy!" gasped Amy, who with Grace, as usual, brought up the rear. "Oh, Betty, be careful! You don't want to get shot!"
Mollie and Betty, panting, just reached the end of the street in time to see the man disappearing down another and knew that pursuit was useless.
"Oh, dear!" cried Mollie, ready to cry with vexation. "If we were only half a dozen men apiece, and could have gotten our hands on him!"
"Yes, I wouldn't very much mind getting my pearl lavallière back," said Grace, as she and Amy joined them.
"And my gold watch," mourned Mollie.
"Look, girls, he dropped something," cried Betty, who had gone on a few steps in advance of them. "And it's—why, I do believe it's——"
"My opal ring!" cried Mollie, staring at it unbelievingly. "Oh, I can't believe it. Give it to me, Betty; it has my initials on the inside. Yes, that's my ring."
The ring passed from one to the other, and the girls regarded it thoughtfully.
"Which proves beyond the shadow of a doubt," said Betty at last, "that Adolph Hensler was the thief."
