Wow, I don’t even know where to begin. This book is amazing to say the least! It took me a little while to get through the almost 600 pages, but they were needed to unravel the mystery that is Dorothy Nicholson. If this review seems a little vague, it is because I don’t want to give away any spoilers; there are just so many events along the way.We start in 1961; Laurel is a 16 year old teenager hiding in the childhood tree house to escape from her sisters. Her Mother, Dorothy comes looking for the cake knife with her baby brother Gerry. Laurel is frozen in shock when she witnesses the most horrific crime. Laurel and her mother are the only people that know what truly happened on that day.Dorothy Nicholson is the best Mother any child could have; she is so creative and full of fun. The children are never without a story. Now in the present and Dorothy is in hospital, she is frail, old and dying. Laurel is visiting with Dorothy and the mystery of the crime is still fresh in her mind. Her Mother is muttering about mistakes and regrets. Laurel cannot forget what happened on that fateful day back in 1961 and decides to find out why it happened and how. Laurel takes it upon herself to investigate her Mother’s past. Her brother decides to help and they both go on the hunt.Going back to 1941; WW2 is in full swing and Dorothy has left her parents and brother behind to find her destiny in London. Dorothy has a boyfriend, a job and then meets the Lady across the road, Vivien. Vivien is the friend that can help Dorothy go places in society. Horrible things start to happen to Dorothy, sad news and betrayal. Dorothy seeks revenge. This revenge is a plan; things don’t go right and Dorothy has to flee. What happened to Dorothy’s boyfriend Jimmy? What is the betrayal that makes Dorothy want revenge? What makes Dorothy commit the crime that ruined Laurel’s childhood? Who is Dorothy from 1941? Can Laurel unravel the mystery that is her Mother?The whole story flows along beautifully, travelling from 1941 to 1961 to 2011 finding all the clues to Dorothy’s past. This is such a beautiful story and the twists along the way are so shocking you are left speechless. The historical part of the book is amazing and in such detail, right down to the clothes and attitudes of the day. Full of action, suspense, romance, fun and the tissues are needed (well for me anyway). This is the first book I've read by this author and I am stunned. I will certainly be picking up her others.
