Raven's Longest Night

John Raven and his wife Kirstie are holidaying in Lisbon at Ilona Szecheyi's villa when Ilona's father Stephen reveals his well-guarded secret: shortly before the communist occupation of Hungary in 1945, he was entrusted with 17 million in government gold bullion. Now, thirty-seven years later, the courts have awarded him full ownership of the money - and the current Hungarian regime is not pleased.
They will stop at nothing to get it back, and when blackmail and murder strike, Raven can't pull out fast enough before he becomes the main suspect .
