Walk, Charles Edmonds

A fabulous gem of unrivaled size and clarity. Rumored to have been the property of Rodrigo Borgia, father of Cesare and Lucrezia. A stone with a history of bad luck attached to it. One time owner Luca Paternostro was murdered by a thief a few days after it came into his possession. A courier was lost at sea while transporting it. Now, the latest owner, Felix Page, a wealthy Chicago financier is found dead in his mansion and the Paternoster Ruby has gone missing once again.
