“Well, you can buy Solingen goods outside Germany. And German tobacco, too. Say in Holland.” “I don’t know what you’re thinking, sir?” “Oh, I think the tobacco was a little error. I think the tobacco ought not to have been there. But it was rather unlucky for Dr. Wilton your bright expert took it for his brand.” The superintendent looked uncomfortable. “Yes, sir, that’s the sort of thing we don’t want to happen. But after all the case didn’t turn on the tobacco. There was the man who swore he saw Wilton leaving Witt’s flat and the finding of the diamonds in Wilton’s room. Without the tobacco the evidence was clear.” “I know. I said the tobacco was superfluous. That’s why it interests me. Superfluous, not to say awkward. We know Wilton don’t use Rauch-tabak. Yet there is Rauch-tabak on the chloroformed pad. Which suggests that some one else was on the job. Some fellow with a taste for German flavours. The sort of fellow who’d use a German key.” “There’s not a sign of Wilton’s having an accomplice,” said Bell heavily. “But of course it’s possible.” Mr. Fortune looked at him with affection. “Dear Bell,” he said, “you must find the world very wonderful. No, I wouldn’t look for an accomplice. But I think you might look for the diamond merchant and the journalist. I should like to ask them who smokes Rauch-tabak.” “There must be an investigation,” Bell sighed. “I see that, sir. But I can’t see that it will do the poor fellow any good. And it’s bad for the department.” Reggie smiled upon him. “Historic picture of an official struggling with his humanity,” he said. “Poor old Bell!” At the end of that week Mr. Fortune was summoned to Scotland Yard. He found the chief of the Criminal Investigation Department in conference with Eddis, a man of law from the Home Office. “Hallo! Life is real, life is earnest, isn’t it, Lomas?” he smiled. The Hon. Sidney Lomas put up an eyeglass and scowled at him. “You know, you’re not a man of science, Fortune. You’re an agitator. You ought to be bound over to keep the peace.” “I should call him a departmental nuisance,” said Eddis gloomily. “In returnin’ thanks (one of your larger cigars would do me no harm, Lomas) I would only ask, where does it hurt you?” “The Wilton case was a very satisfactory case till you meddled,” said Eddis. “Also it was a _chose jugée_.” “And now it’s unjudged? How good for you!” Reggie chuckled. “How stimulating!” “Now,” said Lomas severely, “it’s insane. It’s a nightmare.” “Yes. Yes, I dare say that’s what Dr. Wilton thinks,” said Reggie gravely. “Well, how far have you got?” “You were right about the tobacco, confound you. And the key. Both of German birth. And will you kindly tell me what that means?”
