There's an old movie called "Young Sherlock Holmes", it's not based on any of the original stories and involves a secret Egyptian cult kidnapping and sacrificing young women in a hidden temple in London. They'd also murder people by injecting hallucinogen into them via blowgun (leading to some impressive 80's special effects scenes) which lead to them appearing to lose their minds and commit suicide in public.
