Meanwhile, Willow, a member of the prestigious Prins family who is married to Thomas, heir to House of Prins, is living a life that looks perfect on the outside but is full of tension and secrets. She discovers Xander’s murder is connected to her husband’s business, and her suspicions about her marriage deepen as she uncovers lies about Thomas’s infidelity and shady dealings involving diamonds.
