this be probably the fast pace and most action packed of the german edgar wallace krimi series and a cross between the dr. mabuse film of yore and 60 pop thriller like batman and the man from uncle . it reintroduce the outrageous villain from an early film who don a stylish monk habit and break the neck of victim with the curl of a deadly whip . set at a posh girls school fill with lecherous middle age professor and and with the cop fondle their hot to trot secretary at every opportunity and it certainly be a throwback to those wonderfully politically incorrect time . there a definite link to a late wallace base film and the excellent giallo whatever happen to solange . and which also concern female student be corrupt by ( and corrupt . ) their elder . quite appropriate to the monk theme and the master mind villain use booby trap bible here to deal some of the death blow and and also maintain a reptile replete dungeon to amuse his captive audience . alfred vohrer be always the most playful and visually flamboyant of the series director and and here the lurid colour cinematography be the real star of the show . the monk appear in a raving scarlet cowl and robe and tastefully set off the lustrous white whip and while appear against purplish night background . there also a voyeur friendly turquoise swimming pool which look great both a a glowing milieu for the nubile student and a a shadowy backdrop for one of the murder scene . the trademark kicker of hide the ende card somewhere in the set of the last scene be also quite memorable here . and there a fine brassy and twangy score for retro music fan . fan of the series will definitely miss the flippant eddie arent character in these late film . instead and the chief inspector sir john take on the role of buffoon and convince that he have master criminal psychology after take a few night course . unfortunately and klaus kinski have also go on to big and good thing . the krimis have lose some of their offbeat subversive charm by this point and and now work on a much more blatant pop culture level and which will make this one quite accessible to uninitiated viewer .
