The envelope and the paper inside were waterproof, but they were made of paper after all.
No sooner had it drifted into the furnace than it had turned to ash, leaving not even debris behind.
But that did not include one letter.
This last letter thrown in remained intact.
The envelope was surrounded by flames, yet they could not even curl one of its edges.
Seeing this, the butler first froze, then as if realizing something, he immediately fetched tools to extinguish the fire.
He then put on gloves and carefully retrieved the letter.
Upon closer inspection, the butler found that not only was the envelope unharmed, but it was also free of any dust, leaving him both baffled and frightened.
He was responsible for managing the exterior of the Lorentz Castle and received dozens of traditional letters daily.
These were mostly from the fervent fans outside, which the members of the Lorentz family had stopped looking at after a few views.
