Cheaply made and slow moving; promoted as a follow-up to the Sherlock Holmes adventure "The Spider Woman", but has little to do with it (there is only one small scene even featuring spiders!). Brenda Joyce is beautiful but bland in the lead; Gale Sondergaard is fine but not particularly well-served by the script. Unlike Leonard Maltin, I didn't find this film all that campy - just dull. *1/2 out of 4, mainly for the fire at the end which is not badly done considering the budget.
