To this their entertainers earnestly replied that no such person was in their establishment, that they had no woman servant but the elderly cook and housekeeper, then present, who was neither a girl nor in pink.

After luncheon the guests were taken all over the house, to convince them of the absence of the young woman whom they had seen, and assuredly there was no trace of her.
On returning to the town where they reside, they casually mentioned the circumstance as a curious illusion.

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.

As for the percipients, they each and all remain firm in the belief that, till convinced of the impossibility of her presence, they were certain they had seen a girl in pink, and rather a pretty girl, whose appearance suggested nothing out of the common.

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.
