"A deadly game of cat and mouse unfolds when a housewife with a secret life takes on a tech billionaire with secrets darker than her own . . . from the author of How I'll Kill You. Margaux leads a double life that would make most people dizzy. By day, she's a seemingly ordinary interior decorator with a picture-perfect marriage. By night, she works for a mysterious employer known only as Mr. X. Her specialty: infiltrating the lives of dangerous targets, gaining their trust, and ultimately exposing their crimes. Her latest assignment: Bertram Casimir, a ruthless tech CEO with an empire built on questionable foundations. His own sister is demanding retribution-alleging he stole a groundbreaking app and may be responsible for the suspicious disappearance of an ex-girlfriend. The job seems straightforward, but Margaux quickly discovers Bertram is no ordinary mark. He sees through her carefully constructed facade, matching her move for move. As the lines between hunter and prey blur, Margaux finds herself unexpectedly drawn to Bertram. They share more than she'd like to admit-a dangerous intelligence, a taste for high-stakes manipulation. When the evidence begins to shift, threatening to unravel everything she knows, Margaux realizes this is far more than just another job. Her secrets-and her life-are now on the line. One lie remains, and it might just save her"-- Provided by publisher.
