Very entertaining and I really enjoyed the furious humor (sometimes slap-stick-ish),the overall story arc and ESPECIALLY the super EXCENTRIC set design in the castle: weird chairs looking like an overly sexual female, weird hands-chandeliers in the morgue,... that must be fun while shooting! Overall "Edgar Wallace" vibe, entertainment, not always the "deepest psychology" behind all, but I just loved watching it for fun!

Typical early 60's West German-made English dubbed Edgar Wallace thriller mystery. Involves some individuals trying to get an inheritance they're not entitled to, spooky looking mansions, investigating detectives, and a totally out of his mind scientist. Recommended for fans of the genre.

A priest arriving by train to London collapses while having an orange soda. A doctor appears and says that the man is in having a heart attack and gives him a shot before trying to lift a key, which the police confiscate. The priest dies and the doctor disappears. It transpires that the doctor was carrying one of the keys that tie into a fortune that a soon to be 21 year old Lord is going to be inheriting. It also seems that someone is trying to kill the keepers of the keys in order to get the fortune for themselves. Remake of an earlier film, with both based upon an Edgar Wallace story. This is a good film, but its also a clichéd Edgar Wallace story with everything you'd expect going on-seemingly random murder,a hidden fortune, feuding heirs, lots of red herrings, an old manor house, stalwart police. If you've seen any of the German Wallace films this is going to play like a greatest hits film of sorts. Its not bad, actually its quite good, its just that there isn't anything to make it stand out from the rest of the films in the series so instead of being one of the best it falls down to being one of many. Unremarkable nature of the plot aside this is still a film thats worth seeing because it is very good.
