The Informer
One of the reasons we read foreign mysteries (no matter where we live)  is because they let us weave our way quickly into the cultures of other countries, using crime as the common thread. Akimitsu Takagi's books are uniquely Japanese: they are slightly stiff and formal at first, apparently  treating bloody subjects in a calm and formal manner; only later do we realize how deeply we've become involved.Takagi, born in 1920, wrote his first mystery at the age of 28. He quickly became Japan's most famous mystery writer--a self-taught legal expert whose heroes in the dozens of books he produced until his death in 1995 were usually prosecutors or police investigators. But in this story (part of the publisher's ambitious plan to introduce Takagi's books to a worldwide audience), the focus is on a young stock broker named Shigeo Segawa, trained at a giant brokerage house whose motto was "Money Is Everything." As Takagi tells us, "the pleasure of having money, the admiration for it, the longing for it, and the misery without it--these emotions had eaten their way into Segawa's bones long ago."Crushed and made desperate by a stock market crash in the 1960s, Segawa gets involved in a shady industrial espionage scheme, and twice betrays one of his oldest friends--by seducing his wife and trying to steal the formula for a new chemical process. When his friend is murdered, Segawa becomes the logical suspect. But a sharp young prosecutor named Kirishima begins to think that perhaps the blame lies elsewhere--with the informer who told the dead friend what Segawa had done.
