What brought Captain Hagberd to Colebrook?

When Captain Hagberd went out of tap-room of the New Inn near the harbour, as soon as the door was shut the barber laughed and said: “The old one and the young one will be strolling arm in arm to get shaved in my place presently.” Noticing a stranger listening to him with a vacant grin, he explained, that this queer old Hagberd, a retired coasting-skipper, was waiting for the return of a son of his. Barber said that I think he believe Colebrook is only the place in the United Kingdom for his long-lost sons. So, he sold up his old home in Colchester this is what that brought Captain Hagberd to Colebrook three years ago.
