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.”
