An MI6 network betrayed. A spy on the run. A Father's hunt for the truth. David Harkness, retired MI6 field agent and once a top operative in Tehran, has been out of the espionage game for decades. Now living in self-imposed exile in Barcelona, he has cut himself off from the cloak-and-dagger world he once knew. But when a contact from his past tells him that his daughter has gone missing in Iran, David is plunged back into a world of conspiracy, double-cross and espionage. Set during the maelstrom of 1970's Pre-Revolutionary Iran and the modern terrorism war between East and West, James Quinn's Graveyard of Spies is a thrilling story of one man's quest to discover the truth and protect what he loves the most - no matter what the cost.
