The Gunsmith Down Under — J.R. Roberts

Clint is on the Barbary Coast, enjoying some gambling and some ladies. He runs into a woman he met some years ago, and they become reacquainted. She tells him that she is returning home to Australia to claim an inheritance of some property. She believes she'll need help when she gets there and convinces Clint it would be an adventure. The adventure begins on the ocean liner, and Clint becomes involved in a threatened mutiny. When they reach Sydney they encounter trouble there, and in the Outback, and the adventure becomes much more deadly than Clint anticipated.
