Harriet Hayward

Harriet Hayward (played by Jessica Wallenfels) is the middle child in the fictional Hayward family on the television show "Twin Peaks". The older of her two sisters, Donna is one of the more prominent characters in the show. As such, most of Harriet's presence relates to Donna in some way.

Whereas the youngest sister, Gersten, is depicted as being musically inclined, Harriet is shown to be a poet. She appears twice in the series, and both times feature her reading poetry she has written. In the show's pilot, Donna asks Harriet to lie to their father, Doc Hayward, while she sneaks out the bedroom window to meet James Hurley to discuss the death of Laura Palmer. Harriet, who is busy writing a poem, fails to adequately cover for her sister, however. Harriet's other appearance — the first episode of the second season, "May the Giant Be With You," features her reading a rather eerie poem she wrote about Laura.

Later in the series, Donna begins to suspect that her mother, Eileen may be having or may have had an affair with Ben Horne. This implies that Donna and Audrey Horne could be sisters. Nonetheless, Harriet bears a strong resemblance to Donna. The plot was never resolved, as ABC cancelled the series after the second season.
