On secondment to Interpol's Art Investigation Unit, Patrice Lanier must solve an intriguing puzzle. A painting found on a Finnish rubbish dump may be by Artemisia Gentileschi, contemporary of Caravaggio and friend of Galileo.

With the help of art historian, Chloe Valery, the Finnish Police, and a gaggle of Italian art experts, Patrice must establish the truth. If the picture is genuinely by the renaissance artist, it could be worth more than $5 million, if it's a forgery, it must be destroyed by fire.

Will Patrice be responsible for the destruction of an extraordinary work of art, based only on an uncertain provenance ... or will he discover it's an unknown masterpiece?
