“M-m-m!” said Tavia, thoughtfully. “See here, Doro! Got a hammer?”

“A hammer? Of course! A whole tool chest in my pocket.”

“Something to hammer with, then,” said Tavia, earnestly. “If I had one I could open this door.”

“It’s locked.”

“Of course it is. But the hinges are on this side.”

“Oh! you need a screw-driver!” cried Dorothy, coming over to her.

“Nothing of the kind. I want something to knock out these pins—don’t you see? Then we can lift the door off its hinges and pull the bolt out of the lock. Ha!”

“What is it?”

“I’ve got it!” cried Tavia, under her breath, and immediately dropped down upon the floor and began to take off her shoe.

Quick as it was off, she grasped the shoe by the foot and used the heel to start the pin of the lower hinge. In a moment the steel pin popped out; then Tavia knocked out the one in the upper hinge.
