The Want-Ad Killer features the crimes of one Harvey Louis Carignan, who was able to get out of a death sentence to continue his violent crimes that included rape and murder. I was a little bit misled by the title, which implied that Carignan found his victims through newspaper ads. He did find a few that way, in advertising for help for a gas station, but it appears that the majority of his victims were opportunistic ones, most notably stranded motorists or those trying to hitch rides. This book was written well before the advancement in the field of forensics, so there isn't much in the way of that. The persistence of the police force is pretty prominently featured, and it is a suspenseful read. Not one of my favorite Ann Rule books, but leaps and bounds better than the anthology type books.
