What is 永遠の記憶 about?
According to the publisher's official synopsis, police detective Kaoru Utsumi is stabbed by an elderly man. He survives a suicide attempt but refuses to speak during questioning. Investigators then identify a young woman who bears a grudge against Utsumi, although her connection to the attacker is unclear.
Meanwhile, physicist Manabu Yukawa and detective Shunpei Kusanagi follow a clue found among the elderly man's possessions. The investigation leads them toward what the publisher calls a mystery that must not be forgotten. Further details are being kept spoiler-free here.
Where it fits in the Galileo series
Bungeishunju calls 永遠の記憶 the latest Galileo novel and identifies ten previously published works in the series. On that publisher count, this is the eleventh Japanese Galileo book. The first Manabu Yukawa story appeared in 1996; the first collection,Detective Galileo, followed in 1998.
English-language readers may know the series primarily throughThe Devotion of Suspect X, Salvation of a Saint,A Midsummer's Equation, Silent Parade, andInvisible Helix. That English list is not the complete Japanese series, because several short-story collections have not been published in English.
