Bela Lugosi is in fine form as kindly Dr. Carruthers, who harbors a sinister secret. Resentful of the success of those who purchased a valuable formula from him — though he had turned down an opportunity to partner instead — and who have since become quite wealthy, he has developed a means of taking his vengeance: an aftershave lotion whose scent will attract the attentions of a gigantic killer bat — enlarged by another secret process Carruthers has developed. Reporter Johnny Layton (Dave O’Brien) tries to figure out the multiple killings and places himself in harm’s way as well. Good fun!

  Recommended. Otto finds this one pleasing enough to relax.
