It should have been just a mid-life fling. A guilty indiscretion that Neve Connolly could have weathered. An escape from twenty years of routine marriage to her overworked husband, and her increasingly distant children. But when Neve pays a morning-after visit to her lover, Saul, and finds him brutally murdered, their pied-à-Terre still heady with her perfume, all the lies she has so painstakingly stitched together threaten to unravel. After scrubbing clean every trace of her existence from Saul's life, and death, Neve believes she can return to normal, shaken but intact. But she can't get out of her head the one tormenting question: what was she forgetting? It's brought Detective Chief Inspector Alastair Hitching, and Neve's worst fears, to her door. But with every new lie, every new misdirection to save herself, Neve descends further into the darkness of her betrayal, and more danger than she ever imagined. Hitching isn't the only one watching Neve.
