Sartorius' new nurse Eve (Joan Wyndham) is suspicious and sends the syringe off for analysis. Things get more serious when it is discovered Clifford's son Roger (Arthur Margetson) has been given power of attorney over Clifford's money and thus Sartorius won't get anything unless he gets rid of Roger too...
An odd little film with wall to wall bad/over acting but Karloff is terrific as the sinister scientist. Goya is ridiculously over the top (even biting Roger at one stage) but so entertaining with it. The pace is uneven - either slow or breakneck - and the film is a bit clunky with no real atmosphere. It is all a little weird.
