First, a note about the title. "Pointing the bone" is a kind of magic the native people in the story use to curse their enemies to death: death by suggestion.
Detective Napoleon Bonaparte aka Bony comes to the outback to investigate the disappearance of a jackeroo (ranch hand) Jeffery Anderson. He was out riding the fence line on the Lacy station, Karwir, and failed to return home. His horse came back riderless. Karwir is a large station (what Americans would call a ranch) and although they searched as best they could, no trace could be found of Anderson. But the owner of the station, called Old Lacy, wants to know what happened to him. Enter Bony to solve the mystery of a disappearance that is several months old.
After such a long span of time, not much in the way of trace evidence remains to be investigated. But Bony does his best, spending much of his time scouring the land searching for the minute clues that will lead him to the answer. His investigations cause the local native people to turn against him and they place a curse on him called pointing the bone. This is where they will an enemy to death mainly by informing the target that the curse has been placed on him. It really only works with people who believe it will work. Unfortunately, Bony, due to his native blood, is one of those who believes even though he tries to convince himself he doesn't believe in curses. Will he be able to solve the mystery before the curse does its deadly work?
Fascinating story, not for the mystery, really, but for the picture of life on Australian sheep and cattle stations in the 1940s. Bony, of course, solves the mystery which turns out to be not that mysterious. The only thing I really didn't care for was the silliness involving the curse. I thought Bony was above those kind of superstitions.
