Amos Walker is hired by the wealthy Childs' family to locate their missing son and notify the parents so they can have cops get him off the streets. Walker finds the kid too late. He and three other kids (all college students)are dead by the time he arrives. The rest of the story concerns Walker finding out what really happened.
I have found many of the stories in this series to be uneven. Some of the writers are not fiction writers but journalists and their stories are rarely satisfying. Some also lean so heavily on the city they are set in, they don't tell much of a story. In this case, it is a story that is too familiar. Something you might see on the Rockford Files. Still you can see Estelman's skill. Detroit is not the same city it was in 2007. But as he notes in the story, Detroit has a way of reverting to a particular place. Hope that isn't true this time.
