Miracle for a Madonna — Barbara Cartland

His sister's folly and an aristocratic thief had combined to threaten the reputation of Lord Mere's family. The handsome peer was forced to leave his London pleasures for the ancient palazzi of Florence. While he is recovering his sister's valuable necklace stolen, he discovers there is much more than theft behind the jewelery's disappearance.

It was here in Italy that Florencia, the young and pure flower of a princely family, captured the untouched heart of the gallant Lord Mere, with beauty only the great Raphael ever imagined.... But Lord Mere quickly realises she is desperately unhappy, because she is engaged against her will to her family's long-standing enemy, Vincente de Gorizia, a man with an unsavoury reputation.

In resolving to save Florencia from a tightening web of danger against a background of deadly vendettas and blackmail, Lord Mere risks everything; at stake is a country's priceless art treasure, treason - and his own life....
