The Disappearing Duchess

Twelve-year-old Bianca feels like the luckiest girl in Venice. She's apprenticed to the most famous painter in the world - Annunzio di Lombardi. But one night, Bianca's beloved Lombardi is given a poisoned cup of wine at a party, and collapses - but not before giving Bianca a magical paintbrush, which allows her to travel through hidden doorways throughout the city. Bianca will have to use all of her pluck, courage and cunning to find out who tried to hurt her master - and to discover what is wrong with the Duchess, who is behaving very strangely indeed.
