Query: Out on the Cutting Edge

This is yet another great Matthew Scudder book by Lawrence Block. This guy knows human nature and the streets of New Yorkand it's denizens up close and personal. Great believable characters and a plot line that is imaginative and believable.He understands the AA program and some excellent insights into the people who attend meetings. His characters are portrayed perfectly whether it's the street patios or the black or Irish ones, the way they speak us spot on.I can't recommend Lawrence Block highly enough.
