They say there's no fool like an old fool. Antonio didn't count himself as old but he was more fool than any man ought to be who'd flown around the world and back again so often he might as well have just been going from Deptford to Dartford. There was a lad involved. There's always a lad in the tale, for men like him.
And was there a happy ending? Now that depends on whether you believe what a certain playwright wrote, or whether you want the real story.
