Advice on Reading Materials?

[17uk]

Hello All,

I have just recently finsihed reading a book entitled 'The Treasure Galleons' by Dave Horder. Published 1971. Lucky find the book was, I found it during a visit to a boot sale (garage sale). I was wondering if there are any other books on the subject that anyone could recommend? I found Dave Horner's account of the subject an interesting read and valuable source of information.
Any information would be great for I am at present writing scripts for TV with metal detecting/treasure seeking as its main theme.
