The Spiral Staircase could well be classed as Hollywood's first slasher, despite the fact that it's not accompanied with the blood and gore which came with the subgenre following the success of Halloween (qv) and others.
At the turn of the 20th century, a serial killer is preying on women, mostly young girls, with "handicaps". Dorothy McGuire plays a mute housemaid of a cantankerous, bed-ridden woman in a spooky mansion who suspects she may well be the next victim, and one evening the house sees many visitors who may or may not be the murderer.
As an old-fashioned horror-mystery, the film has much to recommend it, from the atmospheric direction, brilliant cinematography, creepy production design and excellent performances. If violent murders are what you want to see, watch Saw (qv), if it's a bit of suspense and intrigue, give this a go.
8/10
