Madness in the Ruins: A Mason Collins Crime Thriller (previously entitled Ruins of War)

A mutilated body. No witnesses. The only clue, a message, "Those who I have made suffer will become saints and they shall lift me up from hell."
Winter, 1945. Munich is in ruins, and a savage killer is stalking the city.
U.S. Army investigator Mason Collins enforces the law in the American Zone of Occupation. This post is his last chance to do what he loves most-being a homicide detective.
But he gets more than he's bargained for when the mutilated bodies start piling up, panic threatens to tear the city apart, and the army brass start breathing down his neck to solve the case.
Then the murderer makes him a target. Now it's a high-stakes duel, and to win it Mason must bring into deadly play all that he values: his partner, his career-even his life.
