Turnbull felt intuitively that he knew where Rawlings was. On the Centaurus planet—the planet of the City. But where was Duckworth? Reason said that he, too, was at the City, but under what circumstances? Was he a prisoner? Had he been killed outright?
Surely not. That didn't jibe with his leaving Earth the way he had. If someone had wanted him killed, they'd have done it on Earth; they wouldn't have left a trail to Sirius IV that anyone who was interested could have followed.
On the other hand, how could they account for Duckworth's disappearance, since the trail was so broad? If the police—
No. He was wrong. The trouble with intuitive thinking is that it tends to leave out whole sections of what, to a logical thinker, are pieces of absolutely necessary data.
Duckworth actually had no connection with Rawlings—no logical connection. The only thing the police would have to work with was the fact that Scholar Duckworth had started on a trip to Mendez and never made it any farther than Sirius IV. There, he had vanished. Why? How could they prove anything?
On the other hand, Turnbull was safe. The letters from Duckworth, plus his visit to Drawford, plus his acknowledged destination of Sirius IV, would be enough to connect up both cases if Turnbull vanished. Rawlings should know he couldn't afford to do anything to Turnbull.
Dave Turnbull felt perfectly safe.
He was in his hotel room at the Mayfair when the announcer chimed, five hours later. He glanced up from his book to look at the screen. It showed a young man in an ordinary business jumper, looking rather boredly at the screen.
"What is it?" Turnbull asked.
"Message for Dr. Turnbull from Rawlings Scientific Corporation," said the young man, in a voice that sounded even more bored than his face looked.
