At the end of the book what happened to Manderley? Was it burning down like the flash back in the beginning of the book?

Maxim and the narrator begin the long drive back to Manderley. On the way, Maxim calls Frith and learns that Mrs. Danvers has disappeared. He suspects that something might be wrong and decides to drive through the night to reach Manderley. The narrator falls asleep in the car and dreams that she sees Maxim tie a rope of hair around Rebecca’s neck. When she wakes up, she sees an orange glow on the horizon but realizes that it is in the wrong direction to be the sunrise. As they reach the crest of the hill the estate, they see Manderley engulfed in flames.
