Sisters Carrie and Anna Berniers have been supporting their ne'er-do-well brother Julian through various failed businesses; now, he returns home with a sudden fortune and his young bride. Jealousies both old and new will play a part as the sisters try to understand what Julian's been up to, and as his wife wonders if there's another woman involved.
London, 1888: on the night of the third Jack the Ripper killing, soft-spoken Mr. Slade, a research pathologist, takes lodgings with the Harleys, including a gloomy attic room for "experiments." Mrs. Harley finds Slade odd and increasingly suspects the worst; her niece Lily (star of a decidedly Parisian stage revue) finds him interesting and increasingly attractive. Is Lily in danger, or are her aunt's suspicions merely a red herring?
