Arthur W. Upfield: The Mystery of the Swordfish Reef

From the Publisher:
Three men set out from a small Australian seaside town for an ordinary day's fishing -- and simply vanish. There are no clues to their fate, until another fisherman hauls in a gruesome catch -- the head of one of the men, with a bullet hole in its temple.
