though of course I knew that it was not Jules. I certainly was not aware that Miss Spencer was his wife, but I had long suspected that their relations were somewhat more intimate than the nature of their respective duties in the hôtel absolutely demanded. All that I do know of Jules—he will always be called Jules—is that he gradually, by some mysterious personal force, acquired a prominent position in the hôtel. Decidedly he was the cleverest and most intellectual waiter I have ever known, and he was specially skilled in the difficult task of retaining his own dignity while not interfering with that of other people. I'm afraid this information is a little too vague to be of any practical assistance in the present difficulty.' 'What is the present difficulty?' Racksole queried, with a simple air. 'I should imagine that the present difficulty is to account for the man's presence in London.' 'That is easily accounted for,' said Racksole. 'How?

He has several times recently proved himself to be a daring fellow; unless I am mistaken he will shortly prove himself to be still more daring.' 'But what can he do? Surely you don't suggest that he will attempt the life of Prince Eugen in this hôtel?' 'Why not? If Reginald Dimmock fell on mere suspicion that he would turn out unfaithful to the conspiracy, why not Prince Eugen?' 'But it would be an unspeakable crime, and do infinite harm to the hôtel!' 'True!' Racksole admitted, smiling. Little Felix Babylon seemed to brace himself for the grasping of his monstrous idea. 'How could it possibly be done?' he asked at length. 'Dimmock was poisoned.' 'Yes, but you had Rocco here then, and Rocco was in the plot. It is conceivable that Rocco could have
