“My dear fellow!” Lomas was startled. “This isn’t like you.”

“Oh, many thanks. I don’t like men dying, that’s all. Professional prejudice. I’m a doctor, you see. What the devil are we talking for? Who lives at Millfield double three something?”

“We might get at it,” Lomas said doubtfully and rang for Superintendent Bell. “But it’s a needle in a bundle of hay. And if Tetherdown was to be murdered, it’s done by now.”

“Yes, that’s comforting,” said Mr. Fortune.

Superintendent Bell brought a list of the subscribers to the Millfield exchange and they looked over the names of those in the thirty-fourth hundred. Most were shopkeepers and ruled out. “George Coppett don’t buy his fish in Millfield,” said Reggie Fortune. Over the doctors he hesitated.

“You think it’s some fellow in your own trade?” Lomas smiled. “Well, there’s nothing like leather.”

“Brownrigg,” Reggie Fortune muttered. “I know him. 3358 Dr. Jerdan, The Ferns, Chatham Park Road. Where’s a medical directory? 3358 Dr. Jerdan is not in the medical directory. Ring up the divisional inspector and ask him what he knows about Dr. Jerdan.”

There was nothing, Superintendent Bell announced, known against Dr. Jerdan. He had been at the Ferns some time. He didn’t practise. He was said to take in private patients.

“Come on,” said Reggie Fortune, and took the Superintendent’s arm.

“My dear Fortune,” Lomas protested. “This is a bow at a venture. We can’t act, you know. Bell can’t appear.”
