What happened at the end of haunting molley hartley?

In the book "The Haunting of Molly Hartley", at the end of the novel, Molly discovers the disturbing truth behind her visions and their connection to her tragic childhood in the town of Blackmoor. When she returns to the manor, she realizes that her former tutor Isabel Bradley has been manipulating events all along. Bradley had previously lost a child and became possessed by a malevolent spirit, which took over her body and began using her to take children as offerings to maintain its dark powers.

During her final confrontation with Bradley, Molly finds herself surrounded by the tormented spirits of the children Bradley has taken, who appear as ghostly apparitions throughout the story. Molly becomes the voice for all of these troubled souls and confronts the spirit possessing Bradley, demanding that it releases them. Bradley, now tormented by her actions and the spirits she's been suppressing, becomes remorseful and willingly sacrifices herself to free the spirits and end her own agony.

As Bradley fades, the malevolent spirit also departs, allowing the trapped souls of the children to find peace. The ending provides closure to Molly and the spirits as they are finally able to move on, leaving the haunting of Molly Hartley behind and bringing a resolution to the tragic events of Blackmoor.
