My second novel, The Forbidden Zone, an action thriller set in the build up to WW2:


​In the build up to WW2 diamonds were essential for the precision manufacture of military equipment. Britain, Nazi Germany, Europe, America and Japan were all gearing up for war. But most of the diamond mines in the world had been closed since the Wall Street crash of 1929 and there was a critical shortage.  In 1939 the scramble for smuggled and illicitly mined diamonds was unprecedented, particularly from Africa.  Britain and the Union of South Africa were at the forefront of protecting the mines and breaking the smuggling rings supplying Nazi Germany.  It became violent, bloody and personal. It was a race against time.

The key protagonist is Harvey Tremayne, a Cornish mining engineer from Camborne School of Mines, working for the worlds largest diamond mining company in former German South West Africa. He's on a journey of personal revenge and finds himself drawn into a British Secret Intelligence operation to thwart an imminent theft of diamonds by the Nazis.​
"Clandestine danger from an old adversary lurks at every corner in the aromatic wonder of pre-war Tangiers while commandos plan a daring raid in South West Africa as a U-Boat lurks beneath the waves among the Great White sharks of the forbidden zone. Soon-to-be enemies clash, vendettas between nations and men igniting the searing desert in flames. Intense. Gripping. Classic war time action."  Dav Baulch, author of Fortune's Turmoil

“A cracking story, brought alive by a vibrant backdrop and warts-and-all characters, this fast-paced action thriller delivers from the start until its startling and dramatic finale.”  Meg Humphries.
