'I do not.'

'And the reason, if I may ask it?'

'Mr Racksole, we speak in confidence--is it not so? Some years ago my foolish nephew had an affair--an affair with a feminine star of the Berlin stage. For anything I know, the lady may have been the very pattern of her s.e.x, but where a reigning Prince is concerned scandal cannot be avoided in such a matter. I had thought that the affair was quite at an end, since my nephew's betrothal to Princess Anna of Eckstein-Schwartzburg is shortly to be announced. But yesterday I saw the lady to whom I have referred driving on the Digue. The coincidence of her presence here with my nephew's disappearance is too extraordinary to be disregarded.'

'But how does this theory square with the murder of Reginald Dimmock?'

'It does not square with it. My idea is that the murder of poor Dimmock and the disappearance of my nephew are entirely unconnected--unless, indeed, this Berlin actress is playing into the hands of the murderers.

I had not thought of that.'

'Then what do you propose to do to-night?'

'I propose to enter the house which Miss Racksole entered last night and to find out something definite.'

'I concur,' said Racksole. 'I shall heartily enjoy it. But let me tell you, Prince, and pardon me for speaking bluntly, your surmise is incorrect. I would wager a hundred thousand dollars that Prince Eugen has been kidnapped.'

'What grounds have you for being so sure?'

'Ah! said Racksole, 'that is a long story. Let me begin by asking you this.

Are you aware that your nephew, Prince Eugen, owes a million of money?'

'A million of money!' cried Prince Aribert astonished. 'It is impossible!'

'Nevertheless, he does,' said Racksole calmly. Then he told him all he had learnt from Mr Sampson Levi.

'What have you to say to that?' Racksole ended. Prince Aribert made no reply.

'What have you to say to that?' Racksole insisted.

'Merely that Eugen is ruined, even if he is alive.'

'Not at all,' Racksole returned with cheerfulness. 'Not at all. We shall see about that. The special thing that I want to know just now from you is this:

Has any previous application ever been made for the hand of the Princess Anna?'

'Yes. Last year. The King of Bosnia sued for it, but his proposal was declined.'

'Why?'

'Because my nephew was considered to be a more suitable match for her.'

'Not because the personal character of his Majesty of Bosnia is scarcely of the brightest?'

'No. Unfortunately it is usually impossible to consider questions of personal character when a royal match is concerned.'

'Then, if for any reason the marriage of Princess Anna with your nephew was frustrated, the King of Bosnia would have a fair chance in that quarter?'

'He would. The political aspect of things would be perfectly satisfactory.'

'Thanks!' said Racksole. 'I will wager another hundred thousand dollars that someone in Bosnia--I don't accuse the King himself--is at the bottom of this business. The methods of Balkan politicians have always been half-Oriental. Let us go.'

'Where?'

'To this precious house of Nella's adventure.'

'But surely it is too early?'

'So it is,' said Racksole, 'and we shall want a few things, too. For instance, a dark lantern. I think I will go out and forage for a lantern.'

'And a revolver?' suggested Prince Aribert.

'Does it mean revolvers?' The millionaire laughed. 'It may come to that.' 'Here you are, then, my friend,' said Racksole, and he pulled one out of his hip pocket. 'And yours?'

'I,' said the Prince, 'I have your daughter's.'

'The deuce you have!' murmured Racksole to himself.

It was then half past nine. They decided that it would be impolitic to begin their operations till after midnight. There were three hours to spare.

'Let us go and see the gambling,' Racksole suggested. 'We might encounter the Berlin lady.'

The suggestion, in the first instance, was not made seriously, but it appeared to both men that they might do worse than spend the intervening time in the gorgeous saloon of the Kursaal, where, in the season, as much money is won and lost as at Monte Carlo. It was striking ten o'clock as they entered the rooms. There was a large company present--a company which included some of the most notorious persons in Europe. In that multifarious a.s.semblage all were equal. The electric light shone coldly and impartially on the just and on the unjust, on the fool and the knave, on the European and the Asiatic. As usual, women monopolized the best places at the tables.

The scene was familiar enough to Prince Aribert, who had witnessed it frequently at Monaco, but Theodore Racksole had never before entered any European gaming palace; he had only the haziest idea of the rules of play, and he was at once interested. For some time they watched the play at the table which happened to be nearest to them. Racksole never moved his lips.

With his eyes glued on the table, and ears open for every remark, of the players and the croupier, he took his first lesson in roulette. He saw a mere youth win fifteen thousand francs, which were stolen in the most barefaced manner by a rouged girl scarcely older than the youth; he saw two old gamesters stake their coins, and lose, and walk quietly out of the place; he saw the bank win fifty thousand francs at a single turn.

'This is rather good fun,' he said at length, 'but the stakes are too small to make it really exciting. I'll try my luck, just for the experience. I'm bound to win.'

'Why?' asked the Prince.

'Because I always do, in games of chance,' Racksole answered with gay confidence. 'It is my fate. Then to-night, you must remember, I shall be a beginner, and you know the tyro's luck.'

In ten minutes the croupier of that table was obliged to suspend operations pending the arrival of a further supply of coin.

'What did I tell you?' said Racksole, leading the way to another table further up the room. A hundred curious glances went after him. One old woman, whose gay attire suggested a false youthfulness, begged him in French to stake a five-franc piece for her. She offered him the coin. He took it, and gave her a hundred-franc note in exchange. She clutched the crisp rustling paper, and with hysterical haste scuttled back to her own table.

At the second table there was a considerable air of excitement. In the forefront of the players was a woman in a low-cut evening dress of black silk and a large red picture hat. Her age appeared to be about twenty- eight; she had dark eyes, full lips, and a distinctly Jewish nose. She was handsome, but her beauty was of that forbidding, sinister order which is often called Junoesque. This woman was the centre of attraction. People said to each other that she had won a hundred and sixty thousand francs that day at the table.

'You were right,' Prince Aribert whispered to Theodore Racksole; 'that is the Berlin lady.'

'The deuce she is! Has she seen you? Will she know you?'

'She would probably know me, but she hasn't looked up yet.'

'Keep behind her, then. I propose to find her a little occupation.' By dint of a carefully-exercised diplomacy, Racksole manoeuvred himself into a seat opposite to the lady in the red hat. The fame of his success at the other table had followed him, and people regarded him as a serious and formidable player. In the first turn the lady put a thousand francs on double zero; Racksole put a hundred on number nineteen and a thousand on the odd numbers.

Nineteen won. Racksole received four thousand four hundred francs. Nine times in succession Racksole backed number nineteen and the odd numbers; nine times the lady backed double zero. Nine times Racksole won and the lady lost. The other players, perceiving that the affair had resolved itself into a duel, stood back for the most part and watched those two.
