The story is borrowed from many films which preceded this one. We've all seen an example similar to it, at least in general plot, but not often so delectable as Pleins feux sur l'assasin. It contains a buoyancy amid the noirish shadows leading up a castle's hidden stairwells toward serviceable mystery, good kissing and lackadaisical murder. Georges Franju directed this casual plum. How can we resist a peek?
