One of my favourite MM episodes with a twisted atmosphere, an eccentric cast of suspects and rather macabre murders. Add to that there's a headless horseman that adds to the eeriness to it. It's well-paced, has some good twists that I didn't see coming. I know a lot of people prefer John Nettles, but I prefer Neil Dudgen in the role of Barnaby, as he comes across intelligent, sympathetic, suitably dry and doesn't treat his assistants like lackeys.
