In 2007 Simon Toyne quit his job and moved to France to fulfil a long-held desire to write a thriller. After a sleepless night crossing the channel, he and his family abandoned a planned eight-hour drive to their new home and limped instead to the city of Rouen. It was the sight of the sharp spire of Rouen Cathedral piercing the pre-dawn sky that gave birth to the fiction Citadel of SANCTUS and THE KEY. SANCTUS and THE KEY became immediate bestsellers. To date they have been translated into 27 languages and published in 40 countries.
