"It is nothing, Mr. Garrideb. I have figured out your connections. You leave at twelve and should be there soon after two. Then you can be back the same night. All you have to do is to see this man, explain the matter, and get an affidavit of his existence. By the Lord!" he added hotly, "considering I've come all the way from the centre of America, it is surely little enough if you go a hundred miles in order to put this matter through."

"Quite so," said Holmes. "I think what this gentleman says is very true."

Mr. Nathan Garrideb shrugged his shoulders with a disconsolate air. "Well, if you insist I shall go," said he. "It is certainly hard for me to refuse you anything, considering the glory of hope that you have brought into my life."

"Then that is agreed," said Holmes, "and no doubt you will let me have a report as soon as you can."

"I'll see to that," said the American. "Well," he added, looking at his watch, "I'll have to get on. I'll call to-morrow, Mr. Nathan, and see you off to Birmingham. Coming my way, Mr. Holmes? Well, then, good-bye, and we may have good news for you to-morrow night."

I noticed that my friend's face cleared when the American left the room, and the look of thoughtful perplexity had vanished.

"I wish I could look over your collection, Mr. Garrideb," said he. "In my profession all sorts of odd knowledge comes useful, and this room of yours is a storehouse of it."

Our client shone with pleasure and his eyes gleamed from behind his big glasses.

"I had always heard, sir, that you were a very intelligent man," said he. "I could take you round now, if you have the time."

"Unfortunately, I have not. But these specimens are so well labelled and classified that they hardly need your personal explanation. If I should be able to look in to-morrow, I presume that there would be no objection to my glancing over them?"
