In 1940s Japan, just after the end of the Second World War,
the wealthy entrepreneur Sahei Inugami dies at his villa. Don’t get your hopes
up – his death was a natural one. The “Silk King of Japan”, the late Mr. Inugami
lived a long and prosperous life, and his will is to be read aloud when the
entire family is gathered together. The only missing member is Kiyo Inugami, a
soldier and the son of Sahei’s eldest daughter, and thus the reading of the
will is postponed for a few months until Kiyo returns home.
Just before the will is to be read, the famous detective
Kosuke Kindaichi is summoned to the Nasu region by Toyoichiro Wakabayashi, an
employee at the Furudate Law Office which drafted the late Inugami patriarch’s
will. Wakabayashi’s summons is ominous—according to him, the Inugami clan will
be faced with “a grave situation … events soaked in blood.” Unfortunately,
before Kindaichi can get the man to elucidate just what he means by this, he
drops dead from a poisoned cigarette.
Kindaichi discovers that a central figure in the Inugami
household, Tamayo Nonomiya, has been the target of multiple attempts on her
life. The late Sahei Inugami always favoured Tamayo because he owed a debt of
gratitude to her grandfather, who rescued him from poverty. Unfortunately, his
warmth towards her was never reciprocated by the rest of the Inugami clan.
Tensions reach a boiling point when the will is read aloud, and it is
discovered that it hinges on Tamayo and her choice of a husband. And then, the
murders start in earnest…
