London, 1751: It’s hanging day at Tyburn and nine condemned criminals, six men and three women, are about to meet their end on the infamous triple tree. Among the crowd come to see them hang is Jack Blackstone, better known as Blackjack the highwayman. But Jack has not come to Tyburn on this day merely to gawk at the spectacle of a public execution. For among those to be hanged today is Eliza Colson, Jack’s beloved, sentenced to death for a crime she did not commit. Jack is going to save her from the gallows… or die trying.
