Dr. John Watson

Well, for one thing, Mr. Bainbridge disappeared very suddenly from his home one night a little over two months ago.

About a fortnight later, the British Isles began to be flooded by an extraordinarily clever counterfeit sovereign.

Bad joke.

I pointed out to Scotland Yard that there might possibly be a connection between the two events.

You mean Mr. Bainbridge was a counterfeit?

I mean, as the greatest living authority on coins and coinage, he was undoubtedly kidnapped by a band of unusually daring counterfeiters and forced to assist him in their work.

That voice.

Over a hidden speaking tube of some sort, I imagine.

Unless I'm very much mistaken, that voice belongs to my heart adversary.

Greetings, Professor Moriarty.

So now you've taken up counterfeiting.

Have I destroyed so many of your activities that you're running short of funds?

But my dear professor, surely you must realize that danger is the breath of life to me.

On the contrary, Moriarty.

It's you who have gone too far.

Watson, get Sir George out of here.

I'll keep talking to give you a chance to escape.

Was it necessary to kill Bainbridge after you'd finished picking his brains?

Well, dash to that camp.

Why not shot or strangle?
