I saw this for the first time recently aft reading Coventry's glowing review n indeed this one's a very obscure one.

The plot in short - Patients and staff of an isolated mental hospital are being killed off by a hooded figure who stalks the halls. While a doctor is busy experimenting skin grafting on animals, his wife gets concerned when a beautiful guest arrives.

I feel the Korean movie A Tale of Two Sisters n its remake The Uninvited (2009) borrowed from this movie.

Even Beneath (2007) borrowed from this one.

Hey girls! Here's a piece of advice: When you discover a man trying to secretly bury the corpse of someone who has clearly been murdered, don't try to blackmail them - The fact that they are burying a dead body probably means they might be prone to fits of murderous violence, or at least know someone who's mental.

This is a standard template Giallo film with the black gloved killer, sexy victims, loads of suspects, body count and stalking sequences, but it's also fast-paced, fun and of course for this period is set in a huge creepy mansion - there must be millions of them in Italy!

Hey William Bergers! Try to find a better excuse for trying to cover up all the murders at your insane asylum for Giallo Red Herring Actors because the one you gave our heroine was a bit lame. Love that flashback, however! Also, if you want to keep your disfigured sister-in-law secret up on the top floor, give her slippers rather than the giant shoes she had on. And tell her to lift her feet when walking! It is fun that most of the characters own or have something already displayed by the killer (a straight razor, a big black gown etc) and am I going mad or did one of the non-killer character actually murder a coach driver? That was weird. Also, it supposed to be set in Norfolk!

Hey recently unmasked killers! Do not under any circumstances when being chased by an angry mob try to put any height between you and said mob, because this always results in a short but fatal struggle with gravity.

For another, far, far more filthy giallo set in an insane asylum, look no further than Slaughter Hotel!

Mary is a new nurse at the prestigious Vance Clinic which is run by Dr. Robert Vance and his wife Elizabeth.A female thief named Giselle is put in the clinic by Dr.Vance.She begins to hear strange sounds in the attic and discovers badly disfigured woman there.In the meantime a mysterious black cape wearing killer stalks and attacks female patients with a razor.Stylish and sadly neglected Gothic giallo with splendid performance of William Berger and stylish direction by Elio Scardamaglia.Great score by Francesco De Masi plus several suspenseful and pretty violent stalking/murder sequences.It's a crying shame that "The Murder Clinic" is rather forgotten or even ignored by Eurohorror enthusiasts.7 lime pits out of 10.
