"And what does he do with all this gold, you ask? Why, ship it, by using an electrical factory where he makes tubings and fittings--and a good deal of mischief, to boot. The sovereigns are hidden as you have seen, and are shipped out at night in fishing boats, loaded below the water mark--I've helped with the loading myself, so I know--_en route_ for Belgium, where his equally creditable brother, Adolph, receives the tubes and invariably ships them back as being of the wrong gauge. Look here--" He stopped speaking for a moment and, stepping forward, lifted up another tubing from the table, and unfastened it at one of the joints. Then he held it up for all to see. "See that stuff in there? That's tungsten. Perhaps you don't all know what tungsten is. Well, it's a valuable commodity that is mined from the earth, and which is used expressly in the making of electric lamps. Our good friend Adolph, like his brother, has the same twist of brain. Instead of keeping the tubes, he returns them with the rather thin excuse that they are of the wrong gauge, and fills them with this tungsten, from the famous tungsten mines for which Belgium holds first place in the world. And so the stuff is shipped in absolutely free of duty, while our friend here unloads it, supplies the raw material to one or two firms in town, trading under the name of Jonathan Brent (you see I've got the whole facts, Brellier), and uses some himself for this factory, which is the 'blind' for his other trading ideas. Very clever, isn't it?" The judge nodded. "I thought you would agree so, my Lord. Even crime can have its clever side, and more often than not the criminal brain is the cleverest which the world produces.
