Winds of Evil [EPUB ebook] 

When Bonaparte sets out to investigate two bizarre murders near the dusty little outback town of Carie, all the odds are against him. The crimes were committed a year before, the scent cold, and any clues that may have survived have been confused by a ham-fisted city policeman. As Bony follows the trail he is first threatened and then attacked by the mysterious murderer. It’s a case that will tax his ingenuity to the limit… if he lives to see it through.
Excellent set up for a story, good cast of characters, perplexing confusion of suspects, and perceptive unravelling of tangled threads. — Kirkus Review
