Nico’s Garden [EPUB ebook] 

In their sixth adventure Philip, an archaeologist, and Rosalind, an artist, are given a problem to solve: a parcel of scorched pages and broken pottery from wartime Italy. In fact there are three related problems, which involve a mysterious Contessa, a ruthless Mayor, and old families with ambiguous attitudes to ancient tombs. Who were the two giants of Renaissance Florence with an unlikely friendship? The result will change history.
