Helle's most successful novel to date has been Rødby-Puttgarden (2005) in which two sisters working in the perfume sales section of the ferry from Denmark to Germany recall the story of their dead mother. Bogged down in their concern with the past, they seem unable to progress with their lives. It was followed in 2008 by Ned til hundene (Down to the Dogs) about a woman who abandons her former life and is picked up by a couple who try to help her, assigning repetitive tasks for her. It brings out the humdrum routine of uneventful life in the provinces and the slowly evolving relationships between the three main characters.
