The opener for an unfinished third series finds a group of detectives assembled in Paris, where they're bumped off in the manner of Agatha Christie's "And Then There Were None" (aka "Ten Little Indians").

After being resurrected, Dick visits Mae East and decides to tail a strange screaming woman whom he sees in her building.

Dick follows the screaming woman to the theatre, where he learns of her association with Professor Innuendo.
