Hi Cham ..
Many thanks for that link .. Stephen Leather is one of my favourite authors .. I've read all his books to date ..
I particularly enjoyed "The Tunnel Rats" ...
Another author in the same sort of genre is Terence Strong .. well worth reading is his "Tick-Tock Man" ...
Another favourite of mine is Robin Cook (NO .. not the poisonous dwarf who used to be UK Foreign Secretary) .. but an American doctor .. if you like your thrillers with a "Medical" flavour .. this is yer' man ...
