Tony April in The Professor's Diary

On Sunday evening, February 15th, 1898, in Havana Harbor the 6,789-ton second class battleship USS Maine floated peacefully at anchor. One moment later a double explosion ripped her apart, sending her to the bottom along with 260 of her 355 men crew. Only 16 sailors escaped uninjured. Was it an act of war by Spain? Or a calculated "false flag" attack by the United States to provoke a war?
Fast forward to 1972. Private Investigator Tony April gets an enigmatic midnight call from wealthy and beautiful Barbara Anderson. Her explorer grandfather kept a diary that may hold the answer. Problem is, he's buried along with his diary, on a remote jungle mountain in Ecuador. Now everyone wants in. The Rickover Investigation wants to publicize it. Barbara just wants to get her grandfather's remains home. Sydney Street wants the Incan treasure map. And Tony suddenly wants to have a son. Can everyone get what they wish for?
