The tricky part of the investigation lies in establishing the Black Widow's identity. The client wants the Pinkerton Detective Agency to discredit a lady spiritualist who has romantically ensnared his boss. At first Allan refuses the case.

He might have stumbled upon the Black Widow.Kate retraces her investigative trail, hoping to uncover details that will link the woman who killed her father and two husbands to this lady spiritualist. The new investigation pushes Kate to confront the investigative mistakes she made when she was new to the detecting business. What she learns forces her to think about the Black Widow case differently. Alone in wintery upstate New York, separated from her Washington friends and missing Army Captain George Hazzard, Kate must confront the social norms that push some women to violence. Cold and alone, she must ask, is murder ever justified? And do some men need murdering?
