Franklin W. Dixon, The house on the cliff (1927)
“ Frank flashed the light upon his father. Mr. Hardy was inspecting the chamber of the revolver. He held out the weapon with a gesture of despair. There were no more shells.A shot sounded from below and a bullet ripped its way savagely through the flooring but a foot or so away from where the three sat. Another bullet tore through the wood of the trapdoor.The Hardys sprang back and, making as little noise as possible, pressed themselves against the sloping walls of the attic, keeping as far away from the trapdoor as they could. ”
