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.

A key piece of evidence emerges as the list of victims begin to grow, and those seemingly involved with the death of Margaret Mehar begin to panic as they're pursued by both Rijkers and the Widow.

Kenneth moves on pursuing his lead suspect - apprehending him before potential harm is brought to Regina. However, the Widow isn't the only one up to cruel mischief, with the Botticelli sisters taking sinister measures to protect their fortunes.

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.
