The seventh novel in the V.I. Warhawski crime series, set in Chicago, from prize-winning author Sara Paretsky.

V.I. Warshawski's Chicago neighbourhood is prospering. As it's out with the old and in with the new, long-term residents like elderly Hattie Frizell find themselves viciously under threat . . .

But that's not all that's troubling V.I. When the body of her neighbour's friend is found washed up in the Sanitary Canal, her investigations lead her to uncover a world of corporate conspiracy and political corruption involving some of Chicago's most prestigious industrial players. And after several attempts on her life, it seems that this time, V.I. may have dug too deep . . .
