Retro is the 17th Amos Walker novel. I like continuity, but I don’t read them in order.
Retro refers to the storyline nicely. A 1950 murder of a prizefighter ties in with the death of a former 1960s radical who fled the US for Canada in ’68 and gets murdered when he sets foot in Detroit again in 2004. But a plot is a plot, and while this one is interesting and well conceived, it’s simple and straightforward—nothing to make John LeCarre twitter.
Retro also refers to the style Estleman used to tell the story. It’s pure 1940s—classic hard-boiled detective pulp, a world of palookas and dames, of gumshoes and gunsels, topped off with a shot cheap whiskey from the office bottle, doll-face—and don’t you forget it. He must have studied Chandler for a month before writing the first line. If you’ve ever tried to duplicate that noir style, you’ll know it’s not easy. But he did it well, and should be proud of himself. Good hard-boiled dialogue is about as easy as writing lines for a paranoid-schizophrenic.
So, if you’ve exhausted your collection of Philip Marlowe and are looking for a good old-fashioned private eye story, give Retro a try. I score it a 4.5 for the high degree of difficulty.
