Phyfe and Underwood studied the trajectories, projecting them into space, estimating the rate at which the fleet would approach, considering its superior velocity and the divergent courses.

"It's easy enough to determine whether they're following or not," said Underwood. "We could simply change our own course by ninety degrees. Perhaps they haven't detected us after all, but are merely shooting blind in the general direction we might be, based only on the observations of the police as we took off. In that case, they may hope merely to approach near enough to obtain adequate radar echoes."

Dreyer had heard the news over the interphone and came into the navigation cell. He overheard Underwood's last statement.

"Demarzule would not send out a mere fishing expedition," he said flatly.

"Then what's the answer?" Underwood asked, but in his own mind he was evolving a wild theory. He wondered if Dreyer would confirm it.

"If we were merely going blindly into space to escape, Demarzule would have no concern with us, but if we were going to a destination where our arrival would be malevolent to him—then he would be concerned."

Underwood's eyes lighted. He read in Dreyer's face the same conclusions he had reached.

"And Demarzule would send his fleet not after us particularly, but to that destination to see that we didn't reach it. Therefore, this fleet is headed for the Dragboran world!"

"Not so fast!" Phyfe objected. "Demarzule would be assuming that we know where it is. He has no basis for such an assumption."
