Developed by LEVEL-5 and released in 2017 for Nintendo 3DS, Android, and iOS, Layton's Mystery Journey: Katrielle and the Millionaire's Conspiracy is a puzzle-adventure RPG that shifts focus from the series' iconic professor to his daughter, Katrielle Layton. After establishing the Layton Detective Agency in London, Katrielle takes on a series of eccentric cases while searching for her missing father, Professor Hershel Layton. The investigation carries her across recognizable London landmarks — including the Houses of Parliament and Tower Bridge — before drawing her into a larger conspiracy involving seven millionaires. The game features the largest puzzle count in the series to date, alongside a new ensemble cast and a branching mystery narrative. Between cases, players can customize the detective agency's interior and dress Katrielle in different outfits appropriate to each investigation, adding a light personalization element to the familiar puzzle-solving structure.
