Uppermost in the Doctor's mind was the reflection that he of all persons should have been selected by an undiscriminating providence to undergo this distressing and entirely unprecedented experience. It was an ironic commentary upon his reactionary views and his comfortable doctrine of common sense. He had been convinced in spite of himself, and the effort to resist conviction had strained his mental powers uncomfortably. He felt very strongly his inability to cope with the many problems that would be sure to arise in connection with the Clockwork man. It was too much for one man's brain. There would have to be a convocation of all the cleverest men in Europe in order to investigate such an appalling revelation. He pictured himself in the act of introducing this genuine being from a future age, and the description he would have to give of all that had happened in connection with him. Even that prospect set his brain reeling. He would like to be able to shirk the issue. It was enough to have looked upon this archetype of the future; the problem now was to forget his existence. But that would be impossible. The Clockwork man was the realisation of the future There was no evading that. The future. Man had evolved into this. He had succeeded somehow in adding to his normal powers some kind of mechanism that opened up vast possibilities of action in all sorts of dimensions. There must have been an enormous preparatory period before the thing became finally possible, generations of striving and failure and further experiment. But the indefatigable spirit of man had triumphed in the end. He had arisen at last superior to Time and Space, and taken his place in the centre of the universe. It was a fulfilment of all the prophecies of the great scientists since the discovery of evolution. Such reflections flitted hazily through the Doctor's mind as he strove in vain to find a practical solution of the problem. What was the clock? He knew, from hearsay, that it was situated at the back of this strange being's head. Tom Driver had seen it, and described it in his clumsy fashion. Since that episode the Doctor had visualised something in the nature of an instrument affixed to the Clockwork man's head, and perhaps connected with his cerebral processes. Was it a kind of super-brain? Had there been found some means of lengthening the convolutions of the human brain, so that man's thought travelled further and so enabled him to arrive more swiftly at ultimate conclusions? That seemed suggestive. It must be that in some way the cerebral energy of man had been stored up, as electricity in a battery, and then released by mechanical processes.
