"He looks just like a pirate," declared her sister.
"He is a pirate—or a robber—I wager," returned Dorothy.
"Maybe he's one of those horrid men who robbed Stresch & Potter Tuesday night."
"Oh, Dora! Let's hurry by."
Both girls redoubled their efforts at the paddles and the canoe shot past the little cove which lay at the foot of the eminence known as Boulder Head. The black hair and ferocious whiskers of the person upon whom they made these comments dipped down behind a big rock on the shore and disappeared.
"There! he's gone," sighed Dora, with relief.
"I'm glad. Do you suppose he had anything to do with the robbery at Stresch & Potter's department store? They say the thieves got more than ten thousand dollars."
"I don't know whether the lone pirate is one of them or not," laughed Dora; "but somebody must have committed the robbery—and why not he?"
"That's heartless," sniffed Dorothy. "They say that a small boy helped the robbers, too. They had to push a boy through the wire screen they cut out, and he opened a cellar door to let the robbers in."
"Don't I know that? And don't I know who is suspected, too?" returned Dora.
