In November 1903, young women are being killed in London, each with a silk stocking stuffed down her throat. Watson seeks help from the Retirement and disenchanted Holmes, who determines that the victims are well-born ladies, not prostitutes. Evidence found includes a thumbprint, a pair of ladies' dancing shoes, broken glass, a strong smell of chloroform and a silk stocking removed from a victim's gullet. It seems that the killer has a foot fetish.
