Is Dickens' ghost, Jacob Marley based on Cornish surgeon?
The Charles Dickens character Jacob Marley might have been inspired by a Cornish surgeon, according to an amateur historian.
Barry West believes the famous literary ghost is based on a Dr Miles Marley, a 19th Century medical practitioner whom met Dickens in London.
In Dickens' A Christmas Carol, Marley's tormented spectre visits Ebenezer Scrooge on Christmas morning.
The Dickens Museum said it "wouldn't be surprised" if Mr West was correct.
