The Mandrake Assignment by Trevor Gibbons

This was a spy thriller that's storyline was gripping. There is intrigue,tragedy,revenge and betrayal. John Hunter was an officer in British Secret Intelligence, who no longer participates in outside operations, he is desk bound until a scary nuclear threat was uncovered and his wife was murdered. He then embarks on a fact finding investigation that will give him the truth about his wife's death and also a mission that went wrong fifteen years prior. The storyline was wonderful and the characters were well-developed and believable. Thanks to Net Galley and Troubador Publishing,
