Currently Reading - The Borgia Ring, Michael White
W in my catchup quest - so THE BORGIA RING by Michael White - the second of his books I've read - Equinox was a while ago now.
From the Blurb:
When builders dig up an ancient skeleton in the City of London, they have no idea of the poisonous legacy they have just unleashed.
Prologue - Rome, August 1503. Pope Alexander VI had a lead like a huge scrotum. Grease dribbled down his chin and his unusually mean black pupils dilated as he contemplated the mountainous sweet pudding placed before him. His daughter Lucrezia Borgia looked at him and felt vomit rise in her throat.
