This episode concerns an escapee from a mental hospital who is violent criminal and also a "Satanic fundamentalist." Gee whillikers! The plot has some interesting twists and turns, to be sure, building toward a dramatic resolution which is satisfying on some level. But the content is pure Satanic-panic stuff, very characteristic of its time and highly suspect. (There's much talk here of Lammas Day, when "the devil is paid homage," but in fact Lammas is an old harvest festival. In medieval Britain this was the "Loaf Mass" when people would bring a loaf of bread to church. Not very Satanic, I'm afraid.) The climactic Black Mass ritual in the woods is simply laughable. In the end, it's enjoyable in the way that cheesy low-budget horror films can be enjoyed. Pursue this case at your own risk. For my money, the most interesting scene is a discussion between Morse and a female cop which gets into the value of feminism. A subtle moment but intriguing. Watch for it.
