"Even if he's a myth," interrupted Gregg, "he is still worth investigating. What annoys me is your positive antagonism to the idea that he might be possible. You seem to want to go out of your way to prove me in the wrong. I may add, that once a man has ceased to believe in the impossible he is damned."

Allingham shot a look of veiled anger at the other, and prepared to re-enter the car.

"Well, you prove yourself in the right," he muttered, "and then I'll apologise. I'm going to let the Clockwork man drop. I've got other things to think about. And I don't mind telling you that if the Clockwork man turns out to be all that you claim for him, I shall still wish him at the other end of the earth."

"Which is probably where he is now," remarked Gregg, with a slight bantering note in his voice.

"Well, let him stop there," growled Allingham, restarting the car with a vicious jerk, "let someone else bother their heads about him. I don't want him. I tell you I don't care a brass farthing about the future of the human race. I'm quite content to take the good and bad in life, and I want it to go on in the same damned old way."

Gregg beat his fist into his open palm. "But that's just what has happened," he exclaimed, "they've found a way of keeping on just the same. That explains the Clarkson business. If the clock is what I think it is, that precisely is its function."

Allingham shouted out some impatient rejoinder, but it was drowned in the rising roar of the engine as they sped along the road.

So the argument had waged since the telling of Tom Driver's story. Gregg's chief difficulty was to get Allingham to see that there really might be something in this theory of a world in which merely trivial things had become permanent, whilst the cosmos itself, the hitherto unchanging outer environment of man's existence, might have opened up in many new directions. Man might have tired of waiting for a so long heralded eternity, and made one out of his own material tools. The Clockwork man, now crystallised in Gregg's mind as an unforgetable figure, seemed to him to stand for a sort of rigidity of personal being as opposed to the fickleness of mere flesh and blood; but the world in which he lived probably had widely different laws, if indeed it had humanly comprehensible laws at all.

The clock, perhaps, was the index of a new and enlarged order of things. Man had altered the very shape of the universe in order to be able to pursue his aims without frustration. That was an old dream of Gregg's. Time and Space were the obstacles to man's aspirations, and therefore he had invented this cunning device, which would adjust his faculties to some mightier rhythm of universal forces. It was a logical step forward in the path of material progress.
