"I guess you aren't so clever after all," he said. "The note was a fake all right."

"And you had this cab waiting for me on the chance?"

Mr. Parker nodded.

"Sherlock Holmes was right," said Psmith regretfully. "You may remember that he advised Doctor Watson never to take the first cab, or the second. He should have gone further, and urged him not to take cabs at all. Walking is far healthier."

"You'll find it so," said Mr. Parker.

Psmith eyed him curiously.

"What are you going to do with me, Comrade Parker?" he asked.

Mr. Parker did not reply. Psmith's eye turned again to the window. They had covered much ground since last he had looked at the view. They were off Manhattan Island now, and the houses were beginning to thin out. Soon, travelling at their present rate, they must come into the open country. Psmith relapsed into silence. It was necessary for him to think. He had been talking in the hope of getting the other off his guard; but Mr. Parker was evidently too keenly on the look-out. The hand that held the revolver never wavered. The muzzle, pointing in an upward direction, was aimed at Psmith's waist. There was no doubt that a move on his part would be fatal. If the pistol went off, it must hit him. If it had been pointed at his head in the orthodox way he might have risked a sudden blow to knock it aside, but in the present circumstances that would be useless. There was nothing to do but wait.

The cab moved swiftly on. Now they had reached the open country. An occasional wooden shack was passed, but that was all. At any moment the climax of the drama might be reached. Psmith's muscles stiffened for a spring. There was little chance of its being effective, but at least it would be better to put up some kind of a fight. And he had a faint hope that the suddenness of his movement might upset the other's aim. He was bound to be hit somewhere. That was certain. But quickness might save him to some extent.

He braced his leg against the back of the cab. In another moment he would have sprung; but just then the smooth speed of the cab changed to a series of jarring bumps, each more emphatic than the last. It slowed down, then came to a halt. One of the tyres had burst.
