“You swear it won’t hurt me?” she temporized.
“Of course it won’t hurt you. Don’t be a fool.”
“Will you swear it?”
“Yes, yes,” said the other impatiently. “I swear it.”
Tuppence raised a trembling left hand to the glass.
“Very well.” Her mouth opened meekly.
Mrs. Vandemeyer gave a sigh of relief, off her guard for the moment. Then, quick as a flash, Tuppence jerked the glass upward as hard as she could. The fluid in it splashed into Mrs. Vandemeyer’s face, and during her momentary gasp, Tuppence’s right hand shot out and grasped the revolver where it lay on the edge of the washstand. The next moment she had sprung back a pace, and the revolver pointed straight at Mrs. Vandemeyer’s heart, with no unsteadiness in the hand that held it.
In the moment of victory, Tuppence betrayed a somewhat unsportsmanlike triumph.
“Now who’s on top and who’s underneath?” she crowed.
The other’s face was convulsed with rage. For a minute Tuppence thought she was going to spring upon her, which would have placed the girl in an unpleasant dilemma, since she meant to draw the line at actually letting off the revolver. However, with an effort Mrs. Vandemeyer controlled herself, and at last a slow evil smile crept over her face.
