Guys does anyone know the name and author of a book with a mom that went lucid near the end as the daughter slowly uncovered the truth of someone in her family (dad I think) assaulted her s/o mom, one of the sons of the mom saw what happened and the trauma stuck with him for life and he held that against his brother and her s/o, there might've been some Mafia in it, a supposed dead mom came back near the end to shoot the person who almost escaped with all the life changing papers, and a house was burnt on fire with a bunch of precious files inside, also had something to do with a broken necklace the mom had after being assaulted plslslsls
