In the a late October night, two shots ring out when a man answers his door, and the shooter quickly drives away. Colorado Springs detectives, Randall Hunter and James Douglass, assume it's a one-time incident until there is another similar murder . . . and then another. Without any leads to the perpetrator, named'the "e;front-doorkiller"e; by the detectives, all they can do is sit and wait for the next victim. SCALES of JUSTICE is the fourteenth book co-authored by Sandra Wells and Betty Alt. Wells has a Ph.D. from Colorado State University in Fort Collins while Alt has an M.A. from Northeast Missouri State University. Both authors have taught at the university level and now enjoy the "e;fascinating hobby"e; of writing books.
