The Layton Detective Agency, a firm that assists its patrons in solving odd enigmas, is headed by Katrielle Layton—daughter of the celebrated archaeology professor Hershel Layton. Alongside her aide Noah Montoir and the chatty canine Sherl, Katrielle tackles investigations that include a newly acquired haunted house, a gown cursed by a demon, the undead spouse of a client, and even a spectral lighthouse, to name just a few. Beyond these eccentric cases, she has been pursuing another unresolved mystery: her father's disappearance. Establishing the agency was merely the first step toward revealing the truth of his vanishing, a quest that has spanned continents and time, and beyond. As she continues to field client after client, each with increasingly bizarre and strange problems, Katrielle steadily inches closer to solving the greatest puzzle of her life.
