Dr. Watson

It's nearly dinner time.

Why are we wandering about here in the dark instead of having a glass of sherry with the others in the library?

I don't change as practitioner, Watson.

I like to earn my fees.

It occurred to me that a further examination of this dining hall might prove profitable.

Personally, Holmes, I think you're wasting your time on this case.

What makes you think that, old chap?

It's perfectly obvious that young American fellow was impersonating the ghost a few nights ago.

He knew his father was going to die and he wanted to build up the legend so as to make his own claim seem more believable.

That's very sound reasoning, Watson.

Though to be logical in his deception, he should repeat the performance.

Now that his father is dead... Well, ghosts only walk at midnight.

So why don't we go and have a glass of sugar?

What is it, Holmes?

Someone's coming in from the library.

The lighted candle.

Yes?

Who is it?

Yes, it's really quite an effective impersonation.

And the twilight provides most appropriate lighting for his play-acting, too.
