"Well, Will had the code deciphered and found out who wrote the document. It proved, by the way, that Adolph Hensler is one of the most dangerous and most wanted German spies in this country."
"And what else?" cried Mollie, who could never wait for the end of a story.
"The clever part of it," Allen continued, leaning forward, very handsome and eager in the firelight, "was Will's copying of the handwriting on the envelope."
"Sure," chuckled Roy. "I told him I wouldn't be surprised to see him start a life of crime any time now."
"Surely no experienced forger could have done it better," Allen agreed whimsically, while the girls waited with unconcealed impatience. "Anyway, he wrote a short note—a decoy—to Adolph in this handwriting, requesting an interview at the very spot where you girls came upon him."
"Oh!" cried Betty, in dismay. "Then it would have been better if we'd left him alone. We took a chance of spoiling all Will's well-laid plans."
"How could it have been better?" asked Allen. "Will started out to capture him and found you girls had beat him to it, that's all."
"Yes and they might have had a good deal more trouble rounding him up than you did," put in Frank. "From what Will tells us, you girls sure did do a neat job."
The girls flushed with pleasure, but Mollie, being truthful to a fault, put an arm about Betty and told where most of the credit was actually due.
"Why, it was Betty who thought of cutting him off," she said, while Betty vainly tried to stop her. "No, I'm going to tell the truth! And it was Betty that really captured him. She saw him go in the door, followed him, and was holding on for dear life when we came upon her."
