I think we must have the same boxset as I was watching the same disc last night!
I know the Columbo series doesn't "do" menace very often but one scene in that episode has always given me the creeps somewhat.
It's when Ken is driving Jim up to the house by the woods and they're talking about the concept of deja-vu.
It's like Jim has a feeling that all is not well but he can't put his finger on why.
Perhaps it's because the scene takes place in a car which is taking Jim to his death. All that beautiful scenery outside.
Don't know - but it's eerie.
