I recognized the name from the title of the Robert Louis Stevenson story "Markheim". This adaptation, starring Kevin McCarthy, is one of the better I've heard. CBSRMT adaptations of short stories usually add a great deal of business in the form of mediocre soap opera and manage to lose the point of the original.
In this case the expansion is quite reasonable and maintains the thrust of the original while providing McCarthy with the opportunity for some wonderful dialog...
Karl Markheim is an evil character who sets out to have a grand time while doing the maximum harm to those around him. Behind a facade of decency he works toward his stated intention to commit all seven deadly sins and break all ten commandments... But there is a mysterious figure which keeps appearing to him in mirrors.
Very good.
