I'm a bit surprised that most of the reviews of this book are so enthusiastic. It's an undemanding read although I agree with other comments that the basic premise of the plot is jarringly incredible. I would have enjoyed this book more if it had not been written in the present tense, which I find comes between the reader and the telling of the story. I understand the use of the present tense to create a feeling of urgency and tension ... but for a whole book ... why? It imparts an unpleasant, jerky feel to the narrative. Please, Elly Griffiths, abandon this gimmick in your future books.
