"I'm jiggered!" was all that he could exclaim, somewhat mournfully.

Afterwards they stood by the window listening eagerly, every little sound causing them to stir and start. And when the shots were repeated, which was every few moments, they positively jumped.

How slowly those fatal minutes passed too. Clive dragged a battered Waterbury from his waistcoat pocket, shook it violently to make sure that it was running, for, in spite of its general excellence, this same watch had of late struck work on occasion. What else could you expect? The ingenious Clive and Hugh had imagined that they had a startling improvement to add to the watch. It had surprised them that no watchmaker had ever hit upon such a simple invention. The thing was, in fact, brilliant and childishly simple, so much so that they burned to put it into practice. That meant that the cheap but reliable Waterbury possessed by Clive had promptly been laid on the operating table. Its vitals had been exposed. Its springs had been stirred with a canny instrument of Clive's own making, and then, the greatest triumph of all, the simple and brilliant improvement had been added.

"Simply ripping!" was Hugh's enthusiastic comment, as he watched his friend's dexterous fingers. "It'll go like a bird after this. You'll make a pot of money by selling the invention."

Alas! The stupid watch resented this unasked-for interference. There was something wrong with the invention added. Perhaps it didn't fit. Perhaps the vitals of the Waterbury had been slightly injured. Whatever the cause, the watch refused to go regularly after that experiment, even though Clive reluctantly withdrew his brilliant addition from the interior. It had a habit of stopping. Then it would plunge ahead without rhyme or reason. But it was going now.

"He left us two minutes twenty seconds ago," he said hoarsely.

"And gave us the limit of five. My eye! Ain't they shooting! It must be a regular battle."

The shots came frequently still to their ears, sharp and very distinct, while occasionally there was a shout. Hugh looked out of the window, wondering whether anyone passing on the road would hear the noise and come in their direction.

"We'd wave then," he told Clive.

"What?" asked that latter, giving his Waterbury a bang on the stone edge of the window. "Beastly thing's trying to stop. It gave a sort of whir. You know. You've heard it."
