What was the secret of desolate, Soviet-controlled Barren Island in the Arctic Sea? What happened to the Lapp Eskimo who visited Barren and never returned? What was the eyeless steel monster that terrified his fellows? Counter-espionage sent a top agent to investigate. He vanished. Clearly, no possible cover story would protect the next British agent to arrive, but someone had to find the answers. Counter-espionage chose a killer - they sent Simon Larren.
His first book as Robert Charles was 'The Faceless Fugitive' (1963) and up to 2010 he had written 33 novels as such with Blood and Sangria (2010) being the last one.
