First You Fall

When his friend's death is ruled a suicide, Kevin Connor--a hustler by trade, sleuth by default--sets out to prove a case of murder. It doesn't help matters that the victim's grown children, who disapproved of their father's gay lifestyle, are only concerned about their inheritance. But they are not Kevin's only problem. His high-strung mother has moved in with him--and she knows nothing about his questionable . . . job.
