Sherlock Holmes:
Her coat is slightly damp; she's been in heavy rain in the last few hours. No rain anywhere in London in that time. Under her coat collar is damp too; she's turned it up against the wind. She's got an umbrella in her left-hand pocket, but it's dry and unused: not just wind, strong wind, too strong to use her umbrella. We know from her suitcase that she was intending to stay overnight, so she must have come a decent distance, but she can't have traveled more than two or three hours because her coat still hasn't dried; so, where has there been heavy rain and strong wind within the radius of that travel time? Cardiff.

Dr John Watson:
It's fantastic!

Sherlock Holmes:
Do you know you do that out loud?

Dr John Watson:
Sorry, I'll shut up.

Sherlock Holmes:
No, it's... fine.
