This is yet another "Krimi" pairing Christopher Lee and Klaus Kinski; the hero this time around is, like them, a Jess Franco regular i.e. Adrian Hoven, and the leading lady future "Euro-Cult" starlet Marisa Mell. The film, however, is not only inferior to THE DEVIL'S DAFFODIL (1961) – which preceded this viewing – but only marginally a genre entry
as, rather, than a sadistic masked killer (the German "Krimis" were obvious precursors to the Italian "Gialli") we get rival gangs of Chicago hoodlums who improbably relocate to London to first extort and then dispatch various wealthy elders when they invariably turn to Scotland Yard for protection! Why this is done is never quite clear, especially since they never get to collect; incidentally, we start off with one mobster eliminating his opponents – but the only survivor, Kinski, soon sets up his own unit of gun-happy thugs whilst retaining an ostensibly respectable front as a tobacconist. One of the victims bequeaths his fortune to his secretary (Mell) rather than his sole ne'er-do-well relative (who has a propensity for orchids, the only link to the title – that is to say, extremely cursory – provided by the narrative!); still, he proves to be not what he seems – with his final trapping of the heroine inside a bank vault one of the very few scenes pertaining to the form's recognizable style (another highlight has a car going off the rails after a large mirror set up along the road gave the illusion to the bewildered driver of an imminent head-on collision).
Lee does not have much of substance to do as an F.B.I.(!) agent, but he at least gets to display his quick two-gun draw in a shoot-out with one of the baddies. Somewhat more prevalent, regrettably, is a comic-relief butler who happens to have served each of the murdered parties immediately prior to their untimely demise
and, ultimately, even offers his would-be expert services to both one of the perpetrators – who promptly winds up dead himself – and the Police!
