The Dark City by Max Allan Collins takes place in the Cleveland of 1935-36. It features real life G-man Eliot Ness who, having left Chicago behind, now serves as Director of Public Safety in the city of Cleveland.
Appointed to the position by a reform minded mayor, Ness is charged with cleaning up Cleveland's hopelessly corrupt police department. The narrative unfolds in a straightforward manner with fact and fiction comingled to make for very interesting reading. As Ness methodically goes about the task of ferreting out the "bent" cops in his midst, a subplot concerning his personal life is skillfully added in.
The Dark City succeeds in telling an interesting tale. It's a work of fiction but owes much to actual events known to have occured in and around Depression era Cleveland. A solid 4 star effort, well researched and clearly told.
