“I’d risk that,” said Mrs. Vandemeyer cheerfully. “But, as long as you don’t sing out for help, you’re all right⁠—and I don’t think you will. You’re a clever girl. You deceived me all right. I hadn’t a suspicion of you! So I’ve no doubt that you understand perfectly well that this is where I’m on top and you’re underneath. Now then⁠—sit on the bed. Put your hands above your head, and if you value your life don’t move them.”

Tuppence obeyed passively. Her good sense told her that there was nothing else to do but accept the situation. If she shrieked for help there was very little chance of anyone hearing her, whereas there was probably quite a good chance of Mrs. Vandemeyer’s shooting her. In the meantime, every minute of delay gained was valuable.

Mrs. Vandemeyer laid down the revolver on the edge of the washstand within reach of her hand, and, still eyeing Tuppence like a lynx in case the girl should attempt to move, she took a little stoppered bottle from its place on the marble and poured some of its contents into a glass which she filled up with water.

“What’s that?” asked Tuppence sharply.

“Something to make you sleep soundly.”

Tuppence paled a little.

“Are you going to poison me?” she asked in a whisper.

“Perhaps,” said Mrs. Vandemeyer, smiling agreeably.

“Then I shan’t drink it,” said Tuppence firmly. “I’d much rather be shot. At any rate that would make a row, and someone might hear it. But I won’t be killed off quietly like a lamb.”
