A Ticket to the Boneyard — Lawrence Block

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.
