“I see. Just wise precaution. Well, you’re right. I did find something while I was ferreting about upstairs.”
“A locked door. Of course, it mightn’t mean anything, only when I knocked I couldn’t get any reply.”
This story is off to a great start. A bunch of bright young things, a snowstorm, a psychic, a seemingly abandoned house in the middle of nowhere, that was left with tea set out, kettle boiling, and two fires laid on...and then we have a door that has been found locked from the inside. And then isn't.
If I didn't know it any better, I'd say we have the makings of a Murder by Death-style (the film!) comedy.
