After my brother-in-law died in my bed, I went on a killing spree

When Elena wakes beside her dead brother-in-law, her perfect life turns into a nightmare. Framed by her husband, betrayed by her family, and locked in a psychiatric hospital for five years, she returns to find who wanted her destroyed. No longer the broken heiress they buried, she hunts the truth with a dangerous mafia heir at her side. Was the corpse a trap, a warning, or part of a larger conspiracy? This time, every liar will pay.
