The Kreval Poison

When the patriarch of the Kreval chemical empire dies, his twisted will forces his four estranged children into a year-long contest of moral purity for a vast inheritance. But within the manor's suffocating walls, the legacy of a covered-up toxic disaster festers. William Kreval, freshly released from prison for a crime he did not commit, finds his world utterly collapsed. Adrift and hollow, he discovers that meticulously destroying his siblings through poison and psychological manipulation is the only act that makes him feel alive. A chilling Peter Lovesey-esque descent into family corruption and cold-blooded revenge.
