“That’s just it. At neither place was the case out of my sight for a moment.”
“And at the Greenes’?” Markham’s agitation was growing rapidly.
“I went directly to Mrs. Greene’s room, taking the case with me. I remained there for perhaps half an hour. When I came out——”
“You did not leave the room during that half-hour?”
“No. . . .”
“Pardon me, doctor,” came Vance’s indolent voice; “but the nurse mentioned that you called to her to bring Mrs. Greene’s bouillon. From where did you call?”
Von Blon nodded. “Ah, yes. I did speak to Miss Craven. I stepped to the door and called up the servants’ stairs.”
“Quite so. And then?”
“I waited with Mrs. Greene until the nurse came. Then I went across the hall to Sibella’s room.”
“And your case?” interjected Markham.
