An Anagram for Goodbye

Time and luck seem to be running out for The Purple Heart Detective Agency. Violence has a toll. Running afoul of the law has its limits.
But for Clayton Grace, there is a woman involved-- the one who got away. His first love, Linda, the woman who chose another man over him. And now that man is missing. One week into retirement, Grace takes Linda's case against Roddy O'Malley's objections. The path is never easy when the heart is leading the way.
Grace is soon chasing ghosts-- and bank robbers! Later, we see a full contingent of foes: abusive husbands, blackmailers, Russian mobsters, crazy rock 'n' rollers, rapists, and the worst L.A. and Austin, Texas can muster.
Roddy and the crew come to the aid of their brother-in-arms in their relentless way. Things look dire. Can they survive? Is this goodbye?
In Anagram for Goodbye, we find out there is no anagram for goodbye.
