Bride's Veil

The same three Irish characters who were the protagonists of "The perilous Art of Forgetting", William Collins, Peter Boyle and Reginald McKenzie are back.
A few years have passed since then, and they have left Ireland to start a new page of their life in charming Tuscany. Once again they get involved, against their will and expectation, in dramatic happenings and mysterious murders and have to summon up their speculative intellectual talents to unravel the evidences and the plots.
What's happened to the beautiful, rich and spoilt Fiammetta Innocenti only a few days before her wedding?
Was she really killed by Giorgio Cini, the photographer?
