To-night, at eight o'clock, the Continental mail train would start from Charing Cross Station with seventy-five thousand pounds worth of bullion for the Bank of France. If Eustace Margraf succeeded in his enterprise, it would reach Paris with the same weight of valueless shot in the strong iron boxes.

Everything had been nicely and minutely arranged. The shot had been carefully weighed to a quarter of a grain, and portioned into three equal lots to match the cases of bullion, which would be weighed on leaving London, again at Dover, once more at Calais, and finally on arrival at Paris. A key to fit the cases had been secretly made from a wax impression of the original, how obtained none but Margraf knew. This key he would hand to his confederates this evening at Charing Cross Station, after which he would go down by the seven o'clock train preceding the mail.

"A LIFE LIKE THIS WOULD KILL ME!"

The stoker of the mail, an old railway hand, had been bribed, together with the guard in whose compartment the bullion would travel. It had been thought desirable to deal differently with the front guard and the driver; a specially prepared and powerful drug was to be given them in a pint of beer just before starting, which would take effect about an hour after administration and last till the sleepers should be aroused by brandy. During their slumber the stoker would pull up at convenient places on the line to allow the robbers to enter the guard's carriage and leave it with their booty, when they would make off to where Margraf had arranged to meet them; he would manage the rest. The front guard and the driver, meanwhile, would for their own sakes be glad enough to say nothing about their long slumber.

All these arrangements had been made with great nicety, and told over twice; and yet Margraf was uneasy and nervous as he thought of all the risk he ran. Twice he stretched out his hand for the bell-rope for telegram forms to stay the whole business; once he went so far as to ring the bell, but he altered his mind by the time the servant answered it, and ordered hot brandy instead. It was now six o'clock; in another hour he must hand over the duplicate key to his accomplices and board the train for Dover.

Every moment he grew more nervous, his hand became so shaky that brandy failed to steady it; his face grew pale and haggard; his nerves were strung to a painful tension; and all sorts of possibilities of failure in his scheme haunted him till he could have cried out from sheer nervousness.

"God!" he exclaimed, as he drained a glass of brandy and water and rose to go. "A life like this would kill me. Well, this shall be the last risk. If it turns out all right—as it must—I shall give this kind of business up. I shall have plenty then, and old Charlie will go off and live quietly and comfortably."
