When Florence learned of Jeanne’s exciting discovery on Birch Island she was for going there at once.

“You saw him!” she exclaimed. “The boy in the crimson sweater? The firebug?”

“Yes,” Jeanne replied quietly. “The boy in the crimson sweater.”

“What is he like? Does he look dangerous? What if—”

Florence shot a dozen more questions at Jeanne. Strangely enough, the little French girl was quite vague in her answers, much more so than the occasion warranted. And, when the question of her accompanying Florence arose, she pleaded a headache.

“It’s only a two hour’s run in a small motor boat,” Florence said to Dave. “You have another wait of several hours?”

“That’s right.”

“Then suppose I hire the lodge fishing boat and get Indian John to run me over here?”

“O.K. by me. You might take Katie with you. But watch your step! If this fellow is really a firebug, he may be dangerous.”

“I’ll watch,” Florence was off.
