Detectives Kellerman and Lewis have a roadside corpse. They ID him as Edward Dubick, a guard at Central Maryland Psychiatric Center for the Criminally Insane. Conveniently enough, Central Maryland had an escape the previous night. This clue, however, doesn't make Kellerman and Lewis very happy. Because the fugitive at large is one of the smartest and most vicious hit-men in the history of Baltimore homicide.
