This 1968 color German-made feature was one of the last of the Edgar Wallace series, and like the later films it introduced horror and sex elements. The earlier black-and-white films were staples on american UHF TV in the 60s and 70s, and most are fascinating exercises in style and suspense. The later color films wound up being re-titled and shown on the bottom half of double bills at drive-ins in the early 70s, where I originally saw this one, where it was released by Sam Sherman's Independent-International Pictures. It's grotesque, sleazy, and over-the-top, and introduces too many characters, but seeing it again after 25 years I still find it a worthwhile experience and a good way to waste 90 minutes. No one makes 'em like the Germans do!
