Whilst alone at home, Penny shoots and kills an intruder. On her husband's return he identifies the dead man as his colleague Charles Willoughby. Due to the possession of a shot gun without a license and Penny's mental illness, Harry convinces her that they should bury the body in the woods, but Charles Willoughby comes back to haunt Penny.
Kathryn Leigh Scott puts in a rather good performance as a lady who suffers from mental illness; her fragile state is well depicted, though her histrionics and screaming can be straining on the ears. Simon MacCorkindale plays her helpful husband - or is he? It's obvious that it's a Diabolique type of story. In that sense, it's predictable, but it's still enjoyable. Not the best episode, but has some tense moment and a neat twist of a finale, though the special effects are a bit shaky.
