The ending of your novel can be approached in various ways, depending on the tone and direction of the story. However, an intriguing way to end it could be with revelation and resolution. Here are some pointers: Firstly, the kid, let's call him David, digs deeper into the mystery, struggles with the shocking revelation about his beloved grandpa and also with the haunting question of whether blood really is thicker than water. After much deliberation, David decides to confront his parents with the envelope. They are evidently shocked, but his mother confesses that she knew all along about her father-in-law's deeds. She only kept it a secret to preserve the family's honor and protect David from this dark truth. In a twist, David decides to honor his grandmother, Jill, whose memory had been so unjustly tarnished. He collects evidence, risks family ties, and goes to the police with the envelope and his mother's confession. Even though his grandpa is dead, this case reopens and his crime is publically disclosed. The insurance money is donated to a charity or foundation dedicated to helping victims of domestic violence, in Jill's name, and the house is also sold for the same cause. In the end, David vows to keep Jill's memory alive and breaks the cycle of his family's inherited corruption. He learned the value of truth and justice over familial loyalty. His decision to reveal the truth has indeed created friction within his family, but it also gives an ending honoring the innocent and reaffirming David's ethical resolve. Of course, you can employ the specifics of your novel to tweak this ending. The most important thing is keeping it true to your characters and overall story.
