In sixty years no-one called upon Hans Grubber ex German POW to reveal the whereabouts of the stolen masterpieces, gold, and looted diamonds from all over Europe by the Nazi's during WW11.
Then without warning his past caught up with him. And now he became a hunted man.
The Black Cats, a secret German organisation, hid the loot at the end of WW11. The Blue knights a German Mafia, wanted the loot now worth untold millions.
Hidden in Scotland, for over 50 years the loot was moved to north Majorca. It was secretly hidden in an old Monastery in Puerto Soller. Only Hans Grubber knew the secret riddle to its whereabouts. But now Han's was dead. He was the last black cat.
Ex royal marine and army intelligence Officer Harry Cooper, unexpectedly managed to solve the riddle, but only after several brutal murders.
