Gyp's charm--and there was much charm in this lanky girl--lay in her irrepressible spirits. Gyp was certain--and every boy and girl of her acquaintance knew it--to find an opportunity for "fun" in the most unpromising circumstances. No one but Gyp could have known what fun it would be to play hide-and-seek in the halls and rooms of the third floor of Highacres--especially when one had to step very softly and bite one's lips to keep back any sound! It was Jerry's turn to blind. She leaned her arm against the narrow frame of a panel painting of George Washington that was set in the wall at a turn in the corridor. As she rested her face against her arm she felt the picture move ever so slightly under her pressure. Startled, she stepped back. Slowly, as though pushed by an invisible hand, the panel swung out into the corridor. "_Gyp_----" cried Jerry so sharply that Gyp appeared from her hiding-place in a twinkling. "Look--what I did!" Jerry felt as though the entire building might slowly and sedately collapse around her. "For goodness' sake," cried Gyp, staring. She swung the panel out. "It's a _door_! Jerry Travis, _it's a secret door_!" She put her head through the narrow opening. "Jerry----" she reached back an eager hand. "Look--it's a stairway--a secret stairway!" Jerry put her head in. Enough light filtered through a crack above so that the girls could make out the narrow winding steps. They were very steep and only broad enough for one person to squeeze through. "Come on, Jerry, let's----" "Gyp, you don't know where it'll take you----" Jerry suddenly remembered their poor princess in her dungeon. "Silly--nothing could hurt us! Come on. Close the panel--there, like that. I'll go first." She led the way, Jerry tiptoeing gingerly behind her. The door at the top gave under Gyp's push and to their amazement the girls found themselves in the tower room. It was a square room with a sloping ceiling and narrow windows; there was nothing in the least unusual about it. Gyp and Jerry looked about them, vaguely disappointed. It might have been, with its litter of old furniture, chests of books, piles of magazines and papers, an attic room in any house. The October sunshine filtered in thin bars through the dust-stained windows, cobwebs festooned themselves fantastically overhead. The opening that led to the secret stairway appeared, on the inside of the room, to be a built-in bookcase on the shelves of which were now piled an assortment of hideous bric-a-brac which Mrs. Robert Westley had refused to take into her own home. "Well, it's fun, anyway, just having the secret stairway," decided Gyp, scowling at what she mentally called the "junk" about her. "_Why_ do you suppose Uncle Peter had it built in?" Jerry could offer no explanation. "Hadn't we ought to tell someone?"
