(A book in the Murphy series)
A novel by Brian Burks and Gary Paulsen
Sheriff Al Murphy had no jurisdiction in the Arizona territory, but that didnt matter because Risa needed his help and he owed her. Risas husband was a lawyer and a leader in their small Mexican community. A few weeks ago he and their two sons had set out to report two murders by cattleman Ben King, and had disappeared the only trace was their buggy with blood on the seat. Murphy knew it was almost futile for one man to go up against King, but he also found that help came when he least expected it and from the most unlikely of allies.
