Once again Loren Estleman brings us Amos Walker, whose exploits have already won two citations from the New York Times as the Best Mysteries of the Year. Now, Walker undertakes an assignment that brings him up against Detroit drug dealers in the midst of a power struggle. Walker has been hired by a slick television anchorman to track down his 20-year-old son whom he hasn't seen in years. Walker has little trouble locating the son, who soon is murdered. Walker closes the case, but it is reopened by a mysterious Latin beauty who definitely has something to hide. Dope dealers, corrupt and honest cops, a creepy killer and a few vicious dogs thrown in for good measure are all part of Estleman's usual rich, varied and fast-paced plot.
