to hers, evidently meaning to annex the place permanently. These were the right tactics, of course. Even I should have adopted them; but they were opposed to a more subtle and deadly strategy. "Grace" proceeded to prove that being on board the same ship with her did not mean being in her society. She did not appear on deck again. Odell was forced to realise that he had made the girl a prisoner in her cabin. That afternoon the list of passengers was given out, and I searched eagerly for her name. I had not far down the alphabet to go. There she was among the "C's"—"Miss Grace Callender." The name was an electric shock; and seeing it I could guess but too easily why the girl might love a man and run away from him. Nobody who read the newspapers three years ago could have helped knowing who Grace Callender was; and if they forgot, she would certainly have been recalled to their minds a year and a half later. I, at least, had not forgotten. I owed to the "Callender-Graham Tragedy" one detail which had helped to make the success of my novel, and had suggested its name, The Key. Miss Callender was (and is) an American heiress, but England has its own reasons for being interested in American heiresses. Therefore, at the time of the two great sensational events in Grace Callender's life, London papers gave long paragraphs to the story. Her parents—cousins—were both killed in a motor accident in France while she was a schoolgirl at home in charge of her aunt, a half-sister of the father, Graham Callender. Both parents were rich, having, for their lifetime, the use of an immense fortune, or rather the income derived from it. The principal could not be touched by them, but passed to their only child. This arrangement had come about through a family quarrel in the previous generation; but, as Graham Callender and his wife were of opinion that injustice had been done, they wished their daughter to atone for it by her marriage. Half the money ought rightly to have gone to Philip Callender-Graham, a cousin who had been disinherited in their favour. He had died poor, leaving a couple of sons a few years older than Grace. The two had been educated at Graham Callender's expense, and had spent their holidays at his houses in town and country. Grace had grown up to look upon both almost as brothers, though they were only her second cousins. She was fond of the pair—a little fonder of Perry, the elder, than of his younger brother Ned. As for the brothers themselves, it appeared later that both were in love with Grace; but Ned kept his secret and let Perry win the prize. The engagement of Grace
