In the little mountain town of Ruhenhelm, life is simple and peaceful. Neighbors greet each other on the street, and the biggest case the local authorities have to worry about is a lost dog. But this bucolic splendor is about to change. Will Tenma, Grimmer and Inspector Lunge be able to prevent the massacre Johan is planning for this sleepy village and its unkowing inhabitants? Or will the cobbled streets of Ruhenhelm soon run red with innocent blood?

In keeping with the original Japanese format, this book reads from back to front and from right to left.
