Ticket to the Boneyard [EPUB ebook] 

Twelve years ago, Matthew Scudder lied to a jury to put James Leo Motley behind bars. Now the ingenious psychopath is free. And the alcoholic ex-cop-turned-p.i. must pay dearly for his sins. Friends and former lovers — even strangers unfortunate enough to share Scudder’s name — are turning up dead. Because a vengeful maniac is determined not to rest until he’s driven his nemesis back to the bottle…and then to the boneyard.
