Michael Harvey’s new novel, The Chicago Way (Knopf), takes its name from a line spoken by Sean Connery’s character in The Untouchables: “You wanna get Capone? Here’s how you get him. He pulls a knife, you pull a gun. He sends one of yours to the hospital, you send one of his to the morgue. That’s the Chicago way.” But Aristotle-reading PI Michael Kelly has a tool that wasn’t available to Eliot Ness: advanced forensics, and that’s right in Harvey’s wheelhouse (he’s cocreator of the A&E show Cold Case Files). Kelly’s been asked to help solve an eight-year-old rape case by his old beat partner, John Gibbons. But Gibbons is soon shot to death at Navy Pier, and Kelly thinks the old case may be relevant. Enlisting the aid of a childhood friend turned DNA analyst, Kelly dives in, his investigation touching on corrupt cops and a Gacy-like serial killer, with locations like Mr. Beef and the Hidden Shamrock (of which Harvey is co-owner). Forensics may be more exciting on TV, but this is a fun little romp around town. a Wed 9/5, 6:30 PM (wine and cheese reception), Book Stall at Chestnut Court, 811 Elm, Winnetka, 847-446-8880, and Thu 9/6, 7 PM, Book Cellar, 4736 N.
