"Blimey, Holmes," said Dr. Joan Watson as she strolled down the corridor to her sleeping compartment. "That's like the twelfth person on this trip who's had the bloody nerve to call me a foreigner."

"Well, technically, the two of us are both foreigners," said the man normally known as the first consulting detective of the British Isles.

"Yes, that's true," said Dr. Watson. "But I notice they're not calling you a foreigner."

"Well, nonetheless, we should not let other people's shortcomings distract us from this case," said Holmes. "Instead we should rather -- Wait a minute! Where did that dog come from?"

"What dog?" asked Dr. Watson.

"The one down that corridor that looks like a wolf," said Holmes.

"Why, that bloody creature is larger than that cussed beast we saw outside Baskerville Hall," said Dr. Watson. "What makes you so sure it's not a wolf?"

"Because there is no way a wolf like that would have got on board this train without attracting attention," said Holmes. "Also -- Wait! Maybe you're right. Maybe it is a wolf."

"How can you tell?" asked Dr. Watson.

"It seems very interested in your legs," said Holmes.

"Ha-ha, very funny," said Dr. Watson. "No, what makes you really think it's a wolf?"

"Because it keeps looking at your legs -- and at the bottom of your dress," said Holmes.

"So?" asked Dr. Watson. "Is that supposed to mean something?"

"There's an ancient European legend about a man who is pure at heart and says his prayers at night -- oh, I forget the rest of the details -- but anyway, every night of the full moon, said man turns into a vicious creature that is totally obsessed with tearing off women's clothing," said Holmes. "Mind you, I always thought it was a legend but now that I see this creature in the flesh -- well, it's fairly obvious that it's not staring in my direction."

"What can we do?" asked Dr. Watson.

"Well, fortunately, I have a revolver here but unfortunately no silver bullets," said Holmes.

"Why are silver bullets important?" asked Dr. Watson.

"Because --" Holmes started to say but just then, the wolflike creature howled and ran forward.

Despite herself, Dr. Joan Watson found herself screaming while her partner Sherlock Holmes hurriedly got out his gun and fired three shots into the creature's chest.

Had it been a normal animal, that should have put an end to the beast right there but the accursed creature just kept coming -- and coming.

Then the creature grabbed a hold of Dr. Watson's dress with its jaws and proceeded to separate said dress from her body.

"Oh, my God, Holmes!" cried Dr. Watson as she quickly lost her outer layer of clothing. "What should I do?"

"Why, that much is elementary, my dear Watson," said Holmes as he futilely checked his pockets for anything containing silver. "Run!"
