The third in the canon tends to be Blood on Satan's Claw (1970), which is as nauseating as it is beguiling on various levels, Linda Hayden notwithstanding of course, although the sight of Michele (Betty) Dotrice getting turned on by a rape has to be a particular low point on any scale of exploitation. The cinematography is second to none however, one of the most beautifully filmed of all the British horrors. I noticed a vinyl album of the soundtrack in a Manchester record shop recently, a new deluxe edition with some choice scenes on the cover. I note that every time they show that film there's more and more of it cut, and, I must say, rightly so.
