Sherlock Holmes investigates a series of so-called "pajama suicides". He knows the female villain behind them is as cunning as Moriarty and as venomous as a spider. Based on "The Sign of Four" and the short stories "The Dying Detective", "The Final Problem", "The Speckled Band" and "The Adventure of the Devil's Foot".
Gale Sondergaard joins the team for this hour long thriller with Holmes and Watson called in to solve the mystery of the "pyjama suicides". Wealthy, clean-cut, members of society each appear to go bonkers and kill themselves with no apparent rationale. This is a fun little story with some quirkier elements to liven up the investigation - big spiders etc. and the shorter, more compact, duration certainly helps keep it tight.
