Imagine you have an old painting, a Madonna and Child, that has been in your family for years. It is beautiful, serene and spellbinding. It hangs on your wall and for a long time you take it for granted. But curiosity to know more about it gradually grows until it becomes irresistible. You call in the experts. They get excited. What if that old family painting was thought to be by a pupil of Leonardo da Vinci - or even the great master himself? You start researching, communicating with academics and institutions all over the world. The results of your research are nothing short of astounding. What would you do if that painting pointed to one of the greatest heresies of our time? And what if it revealed an incredible story that the Roman Catholic Church has been desperate to keep secret at all costs for centuries? "Da Vinci's Last Commission" by Fiona McLaren is one of the most astonishing detective stories in the history of art. It is also a tale of the courage and tenacity of a woman who challenged the international art establishment, orthodox history and the Church in her quest for the truth.
