Edgar Wallace krimi with a serial killer who leaves the title floral tribute on his (mostly) young female victims. Oh, and there's a heroin smuggling ring Fuchsberger and the inscrutable Lee (funny he makes a more convincing Asian here than as Fu Manchu) are investigating, too.
Not bad, though the intervening half-century makes the identity of the killer not much of a mystery. Filmed simultaneously with British and German leads. The British version appears to be unavailable, though (and possibly lost - BFI has no copy).
