In This Sweet Sickness, Patricia Highsmith, in her own inimitable fashion, has created a complex psychological tale as suspenseful as The Talented Mr. Ripley.

David Kelsey, a young scientist, has an unyielding conviction that life will turn out all right for him; he just has to fix the Situation: he is in love with a married woman. Obsessed with Annabelle and the life he has imagined for them—including the fully furnished cabin he maintains for her—David prepares to win her over, whatever it takes.

In this riveting tale of a deluded loner, Highsmith reveals her uncanny ability to draw out the secret obsessions that overwhelm the human heart.
