"Did Miss Dorland bring it straight up—?" began Parker. Nurse Armstrong broke in upon him.

"If you're thinking, did she put the digitalin into the brandy, you can dismiss that from your mind, constable. If he'd had as big a dose as that in solution at half-past four, he'd have been taken ill ever so much earlier than he was."

"You seem to be well up in the case, Nurse."

"Oh, I am. Naturally I was interested, Lady Dormer being my patient and all."

"Of course. But all the same, did Miss Dorland bring the brandy straight along to you?"

"I think so. I heard Nellie go along the passage on the half landing, and looked out to call to her, but by the time I'd got the door open, I saw Miss Dorland coming out of the studio with the brandy in her hand."

"And where was Nellie then?"

"Just got back to the end of the passage and starting downstairs to the telephone."

"At that rate, Miss Dorland couldn't have been more than ten seconds alone with the brandy," said Peter, thoughtfully. "And who gave it to General Fentiman?"

"I did. I took it out of Miss Dorland's hand at the door and gave it to him at once. He seemed better then, and only took a little of it."
