Ralph Arguello is a criminal who put the street life behind him when he married SAPD detective Ana DeLeon. Now Ana's been gunned down and her fellow cops don't need to look far to find a prime suspect. For Ana recently reopened the most infamous cold case in SAPD history--the unsolved murder on notorious Mission Road eighteen years before that threw the San Antonio underworld into bloody chaos. Ana was about to bring charges against the suspected killer: her husband, Ralph Arguello. San Antonio private investigator Tres Navarre is sure that Ralph didn't do it--and that he didn't shoot his wife. But with the police and the Mafia both out for revenge, there's no one to turn to for help.
