O'Rourke's Law or No Law at All — Michael E. Cook

Sean's new boss understands that although he is a Federal Judge, there is hardly any local law throughout the countryside. With the absence of lawmen, jails, and courts, what law there is must do what is necessary to keep the peace. Sean is just the man for the job. When Sean's friends are in trouble, the trouble makers are dealt with swiftly. When a clan restarts a feud, they soon learn about "O'Rourke's Law." Death comes easily to those who attack Sean and his family and friends. The local undertaker is becoming a rich man.
