“Do you know anything about it, Miss Ames?”

“N—no,” stammered Aunt Abby, trembling, as she looked now at the detectives and then at Eunice.

“Well, it couldn’t have put itself there,” went on Driscoll. “Who else has access to that place?”

Eunice gave no heed to this speech. She gave no heed to the speaker, but stared at him, unseeingly, her gaze seeming to go straight through him.

“Why, the maid,” said Aunt Abby, with a helpless glance toward Elliott and Hendricks, as if beseeching assistance.

“The servants must be considered,” said Hendricks, catching at a straw. “They may know something that will help.”

“Call the maid,” said Shane, briefly, and, as neither of the women obeyed, he turned to Ferdinand, who hovered in the background, and thundered: “Bring her in—you!”

Maggie appeared, shaken and frightened, but when questioned, she answered calmly and positively.

“I put that dropper in the medicine closet,” she said, and every one looked toward her.

“Where did you get it?” asked Shane.
