What did the Otis family found the next morning?​

The next morning, however, when the family came down to breakfast, they found the terrible stain of blood once again on the floor. Washington cleaned it a second time, but the second morning it appeared again. The third morning it was there, too, although the library had been locked up at night by Mr Otis himself

i don't really know the circumstances. i personally think not due to it not being fair for all parties and how hated i'd become if i thought it was a good thing.
