The Sardonic Smile

A tightening of the chest, a sudden convulsion. Only the heels and head touching the floor. Like a bow. Face muscles tightening, eyes staring, teeth clenched, lips pulled back into a sardonic smile. The classic symptoms of strychnine poisoning. When a wealthy landowner dies after eating a trout, freshly caught, the question is who poisoned him? And how? Guest stars Brian Oulton, Amanda Walker, Robert Hartley and Bill McGuirk.
