Of course there were the police. But Theodore Racksole held the police in sorry esteem. He acquainted them with the facts, answered their queries with a patient weariness, and expected nothing whatever from that quarter. He also had several interviews with Prince Aribert of Posen, but though the Prince was suavity itself and beyond doubt genuinely concerned about the fate of his dead attendant, yet it seemed to Racksole that he was keeping something back, that he hesitated to say all he knew. Racksole, with characteristic insight, decided that the death of Reginald Dimmock was only a minor event, which had occurred, as it were, on the fringe of some far more profound mystery. And, therefore, he decided to wait, with his eyes very wide open, until something else happened that would throw light on the business. At the moment he took only one measure—he arranged that the theft of Dimmock’s body should not appear in the newspapers. It is astonishing how well a secret can be kept, when the possessors of the secret are handled with the proper mixture of firmness and persuasion. Racksole managed this very neatly. It was a complicated job, and his success in it rather pleased him.

At the same time he was conscious of being temporarily worsted by an unknown group of schemers, in which he felt convinced that Jules was an important item. He could scarcely look Nella in the eyes. The girl had evidently expected him to unmask this conspiracy at once, with a single stroke of the millionaire’s magic wand. She was thoroughly accustomed, in the land of her birth, to seeing him achieve impossible feats. Over there he was a ‘boss’; men trembled before his name; when he wished a thing to happen—well, it happened; if he desired to know a thing, he just knew it. But here, in London, Theodore Racksole was not quite the same Theodore Racksole. He dominated New York; but London, for the most part, seemed not to take much interest in him; and there were certainly various persons in London who were capable of snapping their fingers at him—at Theodore Racksole. Neither he nor his daughter could get used to that fact.

As for Nella, she concerned herself for a little with the ordinary business of the bureau, and watched the incomings and outgoings of Prince Aribert with a kindly interest. She perceived, what her father had failed to perceive, that His Highness had assumed an attitude of reserve merely to hide the secret distraction and dismay which consumed him. She saw that the poor fellow had no settled plan in his head, and that he was troubled by something which, so far, he had confided to nobody. It came to her knowledge that each morning he walked to and fro on the Victoria Embankment, alone, and apparently with no object. On the third morning she decided that driving exercise on the Embankment would be good for her health, and thereupon ordered a carriage and issued forth, arrayed in a miraculous putty-coloured gown. Near Blackfriars Bridge she met the Prince, and the carriage was drawn up by the pavement.

‘Good morning, Prince,’ she greeted him. ‘Are you mistaking this for Hyde Park?’

He bowed and smiled.

‘I usually walk here in the mornings,’ he said.

‘You surprise me,’ she returned. ‘I thought I was the only person in London who preferred the Embankment, with this view of the river, to the dustiness of Hyde Park. I can’t imagine how it is that London will never take exercise anywhere except in that ridiculous Park. Now, if they had Central Park—’

‘I think the Embankment is the finest spot in all London,’ he said.

She leaned a little out of the landau, bringing her face nearer to his.

‘I do believe we are kindred spirits, you and I,’ she murmured; and then, ‘Au revoir, Prince!’
