Movie set set story of a villain who is removing the heads of his victims and leaving them in boxes to be found. Good thriller is a bit too leisurely for much of its first hour where a great deal seems to happen but nothing seems to get done. It's a lot of looking into red herrings and such. Its not bad but it isn't until the second half that the film really starts to move. It's a good but unremarkable Edgar Wallace adaptation. I've seen the film twice now, and I liked it better the firsts time when I was distracted doing things while it was on, I suggest you do something similar. It's of note for fans of Klaus Kinski since the normal manic actor plays some one seeming restrained and bookish.
