Suddenly Deschamps leant back in his chair.

"Yes," he said, "there can be no doubt about it. We're on the track, if we have not already discovered the most revolutionary theory in wireless telegraphy that the world has known as yet! What we know now, at nine o'clock on a November evening in a power station in Paris, might alter the whole course of life and society all over the world."

The Englishman nodded, with less excited but perfectly sincere agreement.

"Very well, then," cried Deschamps, "will the world ever benefit by our three years' work, our marvellous discovery? No! We're two poor devils, junior engineers of this company on two hundred and fifty francs a month. In all France no one will listen to us, and in all England also, as you have discovered. And why?"

"Oh, what is the use, Emile?" Gregory replied, cutting short his friend. "We have talked it over too many times. It's no good making a song about it. We have not got the money to carry out our experiments thoroughly and to construct our models, twenty thousand pounds—five hundred thousand francs, my friend! And as we shall never get that, no one will listen to us and it will remain for someone else to make our discovery when we're—either when we're dead or still nursing Thierry dynamos at a few francs a day."

As he spoke he rolled up the sheet of drawings and, with a deep sigh, thrust it into the inner pocket of his coat.

"Come along," he said; "we had better be getting home. It is more comfortable there than here, at any rate; and there's still one bottle of Maçon."

They left the little alcoved room, walked slowly down the hall, with a word or two to the foreman, and passed out into the office, where the engineer who was to succeed them and watch through the night was smoking with the timekeeper.

Then, arm in arm, they passed into Paris.

They were a strange couple, these two. Basil Gregory was the son of a Cambridge tutor, who early in his career had gone to Paris as the English master of a famous Lycée. He had married a Frenchwoman, who had died five years after Basil's birth. The boy had been brought up in Paris until he was old enough to go to one of the lesser public schools of England, which was all his father could afford for him. He won a science scholarship from his school to Cambridge, had worked hard and played hard at the University, until an unfortunate encounter with a proctor during one of the evenings of the "May Week" had caused him to be sent down for ever and a day. It was a stupid affair enough, but the hot-headed young man's treatment of the guardian of University morals had been too flagrant to be passed over.
