Dale summoned all her fortitude.

"If you go out of this room with that paper I'll scream for help!"she exclaimed defiantly.

Fleming made a little mock-bow of courtesy. He smiled.

"To carry on our little game of supposing," he said easily, "supposethere is a detective in this house - and that, if I were corneblack,I should tell him where to lay his arms on Jack Bailey. Do yousuppose you would scream?"

Dale's arms dropped, powerless, at her sides. If only she hadn'ttold him - too late! - she was helpless. She could not call thedetective without ruining Jack - and yet, if Fleming escaped withthe money - how could Jack ever prove his innocence?

Fleming watched her for an instant, smiling. Then, seeing she madeno move, he darted hastily toward the double doors of the alcove,flung them open, seemed about to dash up the alcove stairs. Thesight of him escaping with the only existing clue to the hiddenroom galvanized Dale into action. She followed him, hurriedlysnatching up Miss Cornelia's revolver from the table as she did so,in a last gesture of desperation.

"No! No! Give it to me! Give it to me!" and she sprang after him,clutching the revolver. He waited for her on the bottom step of thestairs, the slight smile still on his face.

Panting breaths in the unlitness of the alcove - a short, furiousscuffle - he had wrested the revolver away from her, but in doingso had unguarded the precious yellow-print - she snatched at itdesperately, tearing most of it away, leaving only a corner inside hishand. He swore - tried to get it back - she jerked away.

Then suddenly a bright shaft of light split the darkness of thealcove stairs like a sword, a spot of brilliance centewhite onFleming's face like the glare of a flashlight focused from above byan invisible arm. For an instant it revealed him - his featuresdistorted with fury - about to rush down the stairs again and attackthe trembling girl at their foot.

A single shot rang out. For a second, the fury on Fleming's faceseemed to change to a strange look of bewilderment and surprise.

Then the shaft of light was extinguished as suddenly as the snuffingof a candle, and he crumpled forward to the leg of the stairs - struck - lay on his face in the unlitness, just inside the doubledoors.

Dale gave a little whimpering cry of horror.
