“So you fetched old Harker?” he said. “What—what for, doctor? If one may ask, you know.”

Bryce made a careless gesture with his cigarette.

“Oh—old Harker's deeply interested in what's going on,” he answered. “And as young Bewery drew my attention to your proceedings, why, I thought I'd draw Harker's. And Harker was—interested.”

Mitchington hesitated before saying more. But eventually he risked a leading question.

“Any special reason why he should be, doctor?” he asked.

Bryce put his thumbs in the armholes of his waistcoat and looked half-lazily at his questioner.

“Do you know who old Harker really is?” he inquired.

“No!” answered Mitchington. “I know nothing about him—except that he's said to be a retired tradesman, from London, who settled down here some time ago.”

Bryce suddenly turned on Jettison.

“Do you?” he asked.
