Masaaki Shirei

A hard-working section chief, fast approaching retirement and beset by stress from all directions, joins a jazz band and reignites his youthful passion for the music, giving him a chance to set things right in his life.

When wealthy pharmaceutical magnate Sahei Inugami dies in 1949, his family gathers for the reading of his will, only to discover that his enormous fortune has been left under extraordinary conditions. Detective Kosuke Kindaichi is drawn into the inheritance dispute when the family begins to turn against itself and a series of murders follows. As Kindaichi investigates the Inugami family's tangled relationships and long-hidden secrets, the mysterious return of Sahei's grandson Sukekiyo—whose face is concealed behind a white mask after suffering severe injuries during the war—adds another layer to the deadly mystery.
