Housekishou Richard-shi no Nazo Kantei

Richard Ranasinghe de Vulpian is a brilliant and enigmatic British jewelry appraiser. Seigi Nakata is a young college student. Their worlds are as different as can be, but when a chance encounter leads Seigi to hire Richard to appraise a family heirloom, it sparks a partnership that goes well beyond that one job. Together, the duo investigate jewelry-related cases and solve mysteries, finding the secret messages hidden in the hearts of precious stones–and the hearts of those who possess them.
