Midsummer's Equation
6.7
Masaharu Fukuyama reprises his role from 2008's "Suspect X," playing the physicist-cum-detective Manabu Yukawa. The scientist-sleuth arrives in an oceanside town to speak on a panel. But when a man turns up dead outside the inn where he's staying, Yukawa begins to unravel the connections that tie the victim to the activist daughter of the innkeepers, and a precocious boy who first appears on a train—and keeps popping up. It's a Sherlock Holmes mystery with an environmental twist, and one that should please fans of a classic whodunnit.
