Beth wants to love her new home on a quiet suburban street. She wishes she could make friends with her beautiful neighbour Oksana. She longs for a new group of friends. Welcoming neighbours to visit. Coffee dates and dinner parties. But life here feels so closed. Then Beth runs into Oksana's garden one day to fetch her runaway dog, and she sees something shocking that makes her wonder who her new neighbours really are. A girl in the window. A pale desperate face. A hastily scribbled sign bearing only two words. HELP ME. Who is the girl? What are the neighbours hiding? Sometimes, it's the most perfect neighbours that hide the most terrible secrets.

Thriller writer Susanna is fascinated by human relationships. She can be found people-watching wherever she goes, finding material for her writing. Despite the writer's life, she has an adventurous streak and has swum with whale sharks in Australia, fallen down a crevasse in the French Alps and walked through the sewers of Brighton - not in that order. Her passions include animals particularly her dogs walking in the countryside and tennis, which clears her brain of pretty much everything.
