The Widow strikes again, and Kenneth Rijkers begins connecting the killings to a 12-year-old mystery, while Basil Garvey, a business oligarch, pulls a number of strings to control the investigation.

Enid's newspaper declares another Widow murder; panic rises, and Kashtinsky gets high to keep focused; Eddie tries to flee, but Basil reminds him that he owns him; Kenneth uncovers proof that links the victims to the killing of Margaret Mehar.

The Widow sends a nasty treat to Basil and friends, which sends Kashtinsky over the edge; the Botticelli sisters arrange for Verdi to have their portraits taken; Georges Rondeau, the prime suspect in the murders, preys on Regina.

The Widow's latest victim is found on Valentine's Day, dragged to death behind a horse and made up to look like Cupid; a torn piece of the Widow's weeds sends Kenneth and Regina off on a hunt; Salomé entertains bidders for Verdi.

The pressure gets to Israel, who admits to her and seven other involvements in Margaret's death; Kenneth secures the suspects, freeing only Israel to operate on a friend of Regina's - inadvertently putting her into the Widow's clutches.

With Kenneth's list of suspects either jailed or buried, he sets his sights on the sly magician Georges, who is slowly losing his grip on reality.

With the Widow's final victim nearly in her clutches, Kenneth's time is running out; however, upon revealing the killer's identity he grapples with how to bring justice to the victims.
