Dr. Watson

Undoubtedly, someone knew that the American Walter McMorris was impersonating the ghost and used this macabre method to kill him.

Possibly his claims to the title and estate were valid.

Or perhaps some fanatic was so devoted to the Loch Nair legend that he assumed the role of ghost and killed him for his sacrilege.

Hold the candle a little higher, will you, old chap?

Here you are.

Hello.

Here's a suit of armor, Holmes.

Lying in a heap on the floor.

On the floor, eh?

Whereas it obviously belongs on that stand over there.

It's perfectly clear what's happened.

The second figure used this armor and slipped it back in here while we were examining the dead man.

Possibly, Watson, possibly.

At least this armor gives us a definite clue.

But it limits the field of possible suspects.

Well, it's an interesting fact that the human race has grown definitely larger in the past 400 years.

Very few modern men can wear authentic ancient armor like this.

For example, take the first item on the top of the heap lying on the floor here.

These gauntlets of chain mail.

Start them on.
