“No. I am a detective sent out by the agency which prints theatre tickets for many shows. This isn’t the first time we have had trouble, and I want, if possible, to get on the track of the persons responsible. Do you mind telling me all you can of this?”

Of course Miss Magin was only too glad to do so, and, incidentally, she mentioned the loss of Cora’s automobile. Naturally that brought our friends into the conversation, and the detective, who introduced himself as Mr. Boswell, went over to the girls’ table. He spoke of having been for some time unsuccessfully on the trail of the bogus ticket sellers.

“Taking automobiles is a new line for their activities, though,” said Mr. Boswell. “This may make it easier to catch them.”

“Of course,” suggested Cora, “we are not altogether certain that the same persons who sold Miss Magin the tickets took my auto.”

“Very likely they were,” declared the detective. “They probably realized that they had done all the illegitimate business possible in this neighborhood, and they wanted to get as far away as they could before the fact about the tickets became known. An auto offered the simplest means.”

“I should have locked the ignition switch,” said Cora. “I usually do when I get out. But we thought we would stay only a little while, so I didn’t do it this time.”

“Too bad,” said Mr. Boswell. “If I get on the track of your car, Miss Kimball, I’ll let you know.”

He made a memorandum of the description of the two men as furnished by Miss Magin, and took his departure, promising to let Cora hear from him in case anything developed.

“More of the mystery,” remarked Bess, as she and the others were on their way back in the automobile. “What with this and what may happen at Camp Surprise, I can see we are in for a busy summer.”

And busy enough the girls were during the next week. There were trunks to pack, messages to send to the caretakers at the camp, dresses to have finished in time, and many odds and ends to be looked after before leaving for so long a time.
