tone was non-committal. Then he added negligently: "I suppose you will have no objection to Doctor Drumm continuing with Ada's case."
"Continuing?" Von Blon brought himself up straight in his chair. "I don't understand. You said a moment ago"
"That Ada had been poisoned," finished Vance. "Quite. But d' ye see, she didn't die."
The other looked dumbfounded.
"Thank God for that!" he exclaimed, rising nervously.
"And," added Markham, "we are making no mention whatever of the episode. You will, therefore, be guided by our decision."
"Of course.—And is it permitted that I see Ada?"
Markham hesitated, and Vance answered.
"If you care to—certainly." He turned to Drumm. "Will you be so good as to accompany Doctor Von Blon?"
Drumm and Von Blon left the room together.
"I don't wonder he's on edge," commented Markham. "It's not pleasant to learn of people being poisoned with drugs lost through one's own carelessness."
"He wasn't worrying as much over Ada as he was over Sibella," remarked Heath.
"Observin' fella!" smiled Vance. "No, Sergeant; Ada's demise apparently bothered him far less than Sibella's possible state of health. . . . Now, I wonder what that means. It's an inveiglin' point. But—dash it all!—it everts my pet theory."
"So you have a theory." Markham spoke rebukingly.
