     Vane also published "LX, memoirs of a Yugoslav" in 1977 published in US by Harcourt, Brace and Jovanovic 
( Jovanovic is a fellow Yugoslav) ISBN# 0-15-154797-1.  Vane devotes 4 pages to spear fishing and 4 pages to sharks in this book.  Never the less it is enjoyable reading. 
     Vane passed on about 3-4 years back in England (about 1998).  Interesting note, Reg Valentine certified him as a diver about ten years ago -  seems he didn't have a "C" card and rules are rules especially in old England.
