Dark Feathers: Dance of the Geisha description:

Kate is a photographer and amateur ballroom dancer with a mysterious reputation-each of her dance partners have disappeared. Remy is a private detective married to Amelia, Kate's dance instructor. Remy tells Amelia he has a professional interest in Kate to discover the fates of her previous partners, thus becoming Kate's new dance partner. At first Amelia trusts Remy but soon suspects his interest is romantic, and she attempts to pull Remy back from Kate's arms. As Remy investigates Kate, his former fiancee Juliet becomes Kate's favorite client, further complicating the situation. Remy is unable to discover Kate's secret, and becomes the next possible victim. Amelia then joins the list of Kate's dance partners. She soon finds herself also helplessly chasing Kate. But Kate is unchaseable. A dark power that owns and is owned by Kate will soon take control of everything... then lose control.
