I like a good mystery and this one pulls on all the heartstrings! A woman unable to have children and possibly this which was the cause of her relationship to fracture finds herself on a train to London and an unexpected meeting with a young woman who abandons her baby in Ellen's arms. In the baby bag - a note with Ellen's name - how could this be? Was this planned? By whom and why? Lots of questions which needed answering and kept me thoroughly engaged. Loved it.
