I love the cover of this book, which looks creepy and eerie. From the very first page I knew that this is my sort of book, and I wanted to read on. Whilst on the train, Ellen is asked to hold a young woman’s baby while she takes an important telephone call. But at the next station Ellen sees the young woman on the platform walking away. What’s going on? Why has she left her baby? And what does the strange note she wrote to Ellen mean?
