City of masks
(Book)

"Its 1358, and young Oswald de Lacy, Lord Somershill, is delayed in Venice as he awaits a pilgrim ship to the Holy Land. While the city is besieged by the King of Hungary, Oswald stays at the house of an English merchant, and soon comes under the spell of this decadent and dazzling island state that sits on the edge of Europewhere East meets West. But Oswald has secrets. He is running away from something in Englanda shadow that still haunts him, no matter how much he consoles himself with the delights of Venice. When he finds a dead man at the carnival, he is dragged into a murder investigation that draws him deep into the intrigues of this paranoid, mysterious city. From the dungeons of the Doges Palace to the convent-brothel of Santa Lucia, Oswald must search for a murderer in this bewildering maze of alleys and canals. When he comes up against the feared Signori di Notte, the secret police, Oswald learns that he is not the only one with something to hide. Everyone is watching (or trailing) someone else; and nobody in Venice is who they appear to be. Masks, it seems, are not only for the carnival."--Provided by publisher.
