Just as I had been reading about Mediterranean shipwrecks on the net I happened across a couple of secondhand books...
"The bitter sea" Simon Ball and "Operation Mincemeat" Ben Macintyre, interesting stuff, Operation Mincemeat I struggled to put down and is in places gruesome and amusing, The Bitter Sea is a bit dry and political in places but still excellent reading if you have any interest in history.
And ordered "Caverns measureless to man" by Sheck Exley
