“I know who you are now,” said Nurse Philliter, slowly. “You—you gave evidence against Sir Julian Freke. In fact, you traced the murder to him, didn’t you?”

“I did—it was rather unpleasant,” said Lord Peter, simply, “and I’ve got another little job of the same kind in hand now, and I want your help.”

“Won’t you sit down?” said Nurse Philliter, setting the example. “How am I concerned in the matter?”

“You know Dr. Edward Carr, I think—late of Leahampton—conscientious but a little lackin’ in worldly wisdom—not serpentine at all, as the Bible advises, but far otherwise.”

“What!” she cried, “do you believe it was murder, then?”

Lord Peter looked at her for a few seconds. Her face was eager, her eyes gleaming curiously under her thick, level brows. She had expressive hands, rather large and with strong, flat joints. He noticed how they gripped the arms of her chair.

“Haven’t the faintest,” he replied, nonchalantly, “but I wanted your opinion.”

“Mine?”—she checked herself. “You know, I am not supposed to give opinions about my cases.”

“You have given it to me already,” said his lordship, grinning. “Though possibly I ought to allow for a little prejudice in favour of Dr. Carr’s diagnosis.”

“Well, yes—but it’s not merely personal. I mean, my being engaged to Dr. Carr wouldn’t affect my judgment of a cancer case. I have worked with him on a great many of them, and I know that his opinion is really trustworthy—just as I know that, as a motorist, he’s exactly the opposite.”
