Madam, I'm just a bodyguard

Elite assassin Ethan takes a ten-day job guarding Scarlet Crawford, a gifted pharmaceutical scientist married to New York mafia boss Dominic Vance. Scarlet is not a stranger to him: he once rescued her from a brutal attack, then walked away and left a painful misunderstanding behind. Posing as a security guard, he foils an assassination attempt and becomes her personal bodyguard. When rival heir Luke Sterling sets his sights on Project Vitalis, Scarlet's groundbreaking drug, Ethan meets every danger with merciless force, while Scarlet doubts his real reasons and turns their days into a tense battle of seduction and interrogation.
