In Hangtree, Carson, jailer Walter Parsell, who aspires a detective career and studies criminology, is found on the street outside a robbed jeweler, fatally stabbed as with a prison shunt. Suspect ex-cons include the jail's top-dog, lifer Marcus Lansdale, whom Parsell singled out for transfer to a maximum security prison, as Wayne's no-good father, smuggler Steve Rigsby. Marcus's girlfriend's brother also has a record. Rigbsby calls pa's bluff he can find the killer in no time, which leads to Butch Carwin's drug ring. Patrick meanwhile searches in jail, concentrating on trustees.
