Professor Moriarty

I knew he'd never turn down an invitation involving a corpse in a toga ostensibly drowned in an ancient Roman bath.

You will, Sir George, you will.

Sorry to have to execute you, too.

I'm afraid you signed your own death warrant when you sent for Mr. Sherlock Holmes instead of Scotland Yard.

I rather thought you would, you know.

Ah, well, this is what comes of associating with anyone who is foolish enough to think he can outwit Professor Moriarty.

Just like Aida and her young man.

Isn't it romantic?

You might try singing yourself to death as they did.

Such a waste of time, I always thought.

What a pity Mr. Bainbridge won't be able to join you.

have made such a jolly quartet.
