The person to whom they spoke said, with some interest, "Don't you know that a girl is said to have been murdered in that house before your friends took it, and that she is reported to be occasionally seen, dressed in pink?" They had heard of no such matter, but the story seemed to be pretty generally known, though naturally disliked by the occupant of the house.

An obvious hypothesis is discounted, of course, by the presence of the sister of the young gentleman who farmed the estate and occupied the house. Here is another case, mild but pertinacious.
