‘Your Highness will pardon an old man,’ said Hans, ‘but to say that this wine is poison is to say that I am a murderer. I will prove to you that it is not poisoned. I will drink it.’ And he raised the glass to his trembling lips. In that moment Aribert saw that old Hans, at any rate, was not an accomplice of Jules. Springing up from his seat, he knocked the glass from the aged servitor’s hands, and the fragments of it fell with a light tinkling crash partly on the table and partly on the floor. The Prince and the servant gazed at one another in a distressing and terrible silence. There was a slight noise, and Aribert looked aside. He saw that Eugen’s body had slipped forward limply over the left arm of his chair; the Prince’s arms hung straight and lifeless; his eyes were closed; he was unconscious. ‘Hans!’ murmured Aribert. ‘Hans! What is this?’ Chapter Twenty-Five THE STEAM LAUNCH MR TOM JACKSON’s notion of making good his escape from the hotel by means of a steam launch was an excellent one, so far as it went, but Theodore Racksole, for his part, did not consider that it went quite far enough. Theodore Racksole opined, with peculiar glee, that he now had a tangible and definite clue for the catching of the Grand Babylon’s ex-waiter. He knew nothing of the Port of London, but he happened to know a good deal of the far more complicated, though somewhat smaller, Port of New York, and he was sure there ought to be no extraordinary difficulty in getting hold of Jules’ steam launch.

But the fact is, there are hundreds of men between St Katherine’s Wharf and Blackwall who literally know the Thames as the suburban householder knows his back-garden--who can recognize thousands of ships and put a name to them at a distance of half a mile, who are informed as to every movement of vessels on the great stream, who know all the captains, all the engineers, all the lightermen, all the pilots, all the licensed watermen, and all the unlicensed scoundrels from the Tower to Gravesend, and a lot further. By these experts of the Thames the slightest unusual event on the water is noticed and discussed--a wherry cannot change hands but they will guess shrewdly upon the price paid and the intentions of the new owner with regard to it. They have a habit of watching the river for the mere interest of the sight, and they talk about everything like housewives gathered of an evening round the cottage door. If the first mate of a Castle Liner gets the sack they will be able to tell you what he said to the captain, what the old man
