Murder by moonlight

"What's a nice, proper dame like Joan Parker doing in a place like Dick Moonlight's office? The scar running down her face-- from the business end of an axe-- has something to do with it. Shortly after the attack that killed her husband and left her for dead, she pointed the finger at her son Christopher, who now sits in jail. But the woman insists the police have it all wrong-- Christopher didn't do it-- and she just needs the private eye to prove it. Moonlight knows mothers will say anything to protect their kids. He also knows how the police can make a mistake and run with it. Having been nearly dead a time or two himself makes Moonlight a little more empathetic. He takes the case, and soon the clues lead him toward something more sinister than he's ever seen before" -- p. [4] of cover.
