As it happened I thought about including that conspiracy - one of many - it was in Howard's book. As I remember it (I'm tired), Doria didn't believe it when someone warned him about it (like Stalin and warnings about the Nazi invasion). Poor Fieschi, trying to board a ship, slipped on a plank and fell into the sea, wearing armour he sank to the bottom. Leaderless the conspirators gave up and fled. Doria was ruthless in revenge, had some beheaded and had Fieschi's body thrown back into the harbour.

That do ? :-)

Cemeteries ? - plenty of time for them - much later - I hope :-)

Maybe it's because I'm a Londoner - that I moved to Nice.
