The Mediterranean Caper

Dirk Pitt is up against an international drug smuggling ring and the evil Bruno Von Till, a German pilot who survived both World Wars to become one of the most ruthless smugglers in history. The novel is set in the Aegean Sea, where Dirk Pitt has been sent with Al Giordino to assist Rudi Gunn with an expedition being conducted by NUMA.

Dirk Pitt, Special Projects Director for the National Underwater and Marine Agency, and his Deputy Special Projects Director, Al Giordino, are traveling to their assignment in the Aegean Sea in Dirk's PBY Catalina when they receive a mayday distress call from the control tower at the nearby Brady Air Force Base on the Greek island of Thásos. The tower reports that they are under aerial attack by a World War I era German Albatros D-3 biplane painted a startling bright yellow and bearing the familiar black Maltese Cross of World War I Germany. The biplane, with its top speed of just 103 mph, is strafing the runways and destroying multimillion-dollar F-105 Starfire fighters[1] and C-133 Cargomasters without a shred of resistance. Dirk and Al, armed with nothing more than a couple of rifles in their World War Two flying boat face-off against the World War I fighter and its machine guns. After a spectacular dogfight they exit the field of battle victorious.

Dirk has been sent to the Aegean to meet Commander Rudi Gunn, captain of the NUMA research vessel First Attempt, to try to get to the bottom of the recent spate of mishaps on its current assignment. The First Attempt is on a research expedition attempting to find a living fossil lovingly named The Teaser, which scientists believe may be living evidence of the development of the first mammal.

Following his fight with the biplane Dirk goes for a midnight swim and meets a beautiful young woman named Teri von Till whom he quickly seduces. She invites him to dinner at her uncle's villa that evening where Pitt is introduced to the book's primary villain, Bruno von Till. Pitt learns that von Till is an old comrade in arms of Lt. Kurt Hiebert, a World War I flying ace known as the Hawk of Macedonia, whose trademark was a bright yellow Albatross biplane.

After dinner, he confronts von Till about his involvement with the attack on the airfield and while von Till admits nothing he forces Pitt to leave the villa at gunpoint through a door that leads him into what is known as the Pit of Hades. It is later explained that the Pit of Hades is a labyrinth once used in ancient Greek times when the villagers sentenced a convicted felon to death. The person sentenced to die was given the choice of an instant death or choosing the Pit of Hades. The labyrinth had only one entrance, a concealed exit, and roaming amongst the many passages was a hungry lion. In recorded history no one had successfully found the exit before the lion found them. While von Till does not have a lion he does have a very large white German Shepherd with which Dirk Pitt engages in a mortal struggle.

Following his successful escape Pitt is taken into custody when he returns to seek his revenge on Bruno von Till and is captured escaping the villa with Teri von Till as his prisoner. It is later revealed that Bruno von Till has been under surveillance by agents of Interpol and Inspector Hercules Zacynthus of the United States Federal Bureau of Narcotics. The inspector explains that von Till is suspected of being a world-class smuggler responsible for the transportation of all types of goods related to many heinous criminal acts. These acts include the great Spanish gold theft in 1954 which nearly toppled the Spanish economy; the mysterious disappearance of 85 high-ranking Nazi officers from Germany at the end of World War II and their sudden reemergence in Buenos Aires; and the abduction of a bus full of teenage girls in Naples, Italy who were sold into white slavery in Casablanca. The inspector now believes that von Till is attempting to smuggle nearly half a billion dollars worth of heroin into the United States using his fleet of cargo ships called Minerva Lines.

Despite the best efforts of Interpol, the Federal Bureau of Narcotics, Customs, and many other law enforcement agencies they have been unable to catch Bruno von Till transporting anything illegal on any of his ships. Pitt eventually discovers that von Till, using the resources of his shipping line, has raised the sunken wrecks of the German U-boat U-19 and a Japanese I-Boat class submarine which he has been using as part of a smuggling operation. Von Till has converted a German submarine into a completely automated smuggling craft that can be easily attached or detached from the holds of his cargo ships.

Using Pitt's surmises as a basis for action, the inspector launches a campaign to capture as many distributors of heroin in the United States as possible. However, Pitt suspects that Bruno von Till is aware of the approach of Interpol and the Federal Bureau of Narcotics and he launches his own desperate mission with Al and members of the crew of the First Attempt in a last-ditch effort to stop von Till before he can escape and set up his nefarious drug smuggling operation somewhere else. Pitt succeeds in defeating von Till and finds a Teaser in the process for Admiral Sandecker.

The Mediterranean Caper is different from most novels in the pantheon of the Pitt thrillers in that it does not start with a prologue set in the past. However, a number of true life people and events are mentioned during the course of the novel. These would include the spy Mata Hari, the ghost ships Mary Celeste and Flying Dutchman, and a variety of Nazi war criminals including Martin Bormann and Hermann Göring. A reference is also made to the gruesome keelhauling of a sailor on HMS Confident in 1786[3] The novel also refers to Ceylon, which by the time it was published had been renamed Sri Lanka.
