Only a month before he had gone to Hardress with the plans of a new type of submarine boat, which he, of course, firmly believed would revolutionise naval warfare. It would only have cost a few hundred pounds to build a model and demonstrate the truth of his theory, but Hardress had kindly but firmly refused to do it. This refusal had soured him utterly, and put him in exactly the frame of mind readiest to succumb to the temptation to commit the only crime of his life.

Sophie had heard something of this in conversations at the Court and on board the yacht, and she instantly divined that if she was to find an instrument to work out her scheme she would find it in the disappointed inventor—and she was right.

Like every man who believes himself to be a genius, and is not, Edward Williams was intensely vain, and when the beautiful and brilliant countess one day asked him to show her over the engines and explain their working he naturally felt intensely flattered. Then Sophie had skilfully led the conversation to his own inventions, sympathised with him very sweetly, and assured him that in Russia such genius as his would certainly not go unrecognised. "But these English," she said, "are always the last to accept new ideas or properly reward their clever men."

After that he had been as wax in her skilful hands. She had even led him to believe she was not indifferent to him personally. After this she had infatuated him still further by giving him appointments in secluded parts of the Court grounds; and so she had gradually led up to the proposal which he had now definitely accepted.

For reasons of state, it was all-important that the Nadine should never reach America. Not the slightest harm was to come to anyone on board her: they would simply be brought back and landed in France, free to get home as they pleased. All that was wanted was a delay of a couple of days or so. Therefore, if the engines of the Nadine broke down at a certain spot in the Atlantic, and remained helpless until the Vlodoya overtook her, he was to receive five thousand pounds in gold and a lucrative dockyard appointment in Russia, which would give him every opportunity of working out his inventions.

To such a man, embittered by disappointment and soured by a sense of imaginary wrongs, such a dazzling temptation was irresistible; and that was why Edward Williams was leaning over the rail of the Nadine a couple of hours before she was to start, dreaming dreams of revenge on those who had wronged him, and of fortune and fame among his country's enemies.

The party from Orrel Court drove down to Southampton immediately after lunch to enable the ladies to do a little final shopping before going on board.

In the course of the afternoon Chrysie and Lady Olive went into the telegraph office to send off a few farewell wires to friends. As they entered, Miss Chrysie's quick eyes at once caught sight of Felice, the marquise's maid, leaning over one of the compartments. She touched Lady Olive's hand and nodded towards her, and said:

"I guess I'd like to see that telegram."

And then, in the most unprincipled fashion, she strolled along the compartments as though she were looking for a form, stopped a moment and looked over the maid's shoulder. Then she came back and did it again. Meanwhile the other compartments had been occupied; so she just stood about until Felice had finished, and then took her place.
