Throughout the winter and spring, as Sheehan talked to Wheaton and Jenkins, he had something else on his mind: a two-year-old bombing in Nicaragua. On May 30, 1984, a bomb had exploded at a press conference in La Penca, Nicaragua, held by Eden Pastora, a maverick Contra leader who resisted cooperating with the CIA and the main Contra force. Several people were killed, but not Pastora. Afterward, Tony Avirgan, an American journalist who suffered shrapnel wounds at La Penca, and his wife, Martha Honey, set out to uncover who had plotted the attack. A year later, they produced a book that charged a small group of Americans and Cuban exiles-some with ties to the CIA and the Contras-with planning the murderous assault. One of the persons they fingered was John Hull, a Contra supporter with a spread in northern Costa Rica and a relationship with North and the CIA. Their report noted that some Contra supporters were moonlighting in the drug trade.
Hull sued the couple for libel in Costa Rica. He demanded $1 million. Avirgan and Honey, who lived in San Jose, received death threats. They considered retaliating by filing a lawsuit in the States against individuals in the secret Contra-support network. But they could find no lawyer to take such a difficult case. Eventually Sheehan was recommended to them. They checked him out. The reports were mixed. But he had one undeniable positive attribute: he would accept the case. The couple retained him.
Come late spring of 1986, Sheehan was mixing with spooks in the Washington area, and he was pondering how to craft a lawsuit for Avirgan and Honey. He collected information on the Contra operation. He drew closer to Wheaton, who had a new tale every time they met. Then Sheehan made a pilgrimage to meet the dark angel of the covert crowd: Ed Wilson.
The imprisoned rogue officer made Sheehan's head swim. The essence of Wilson's story, Sheehan claimed, was that the Agency in 1976 had created a highly secretive counter terrorist unit modeled on the PRUs of Vietnam and had run this entity apart from the main bureaucracy. The mission: conduct "wet operations" (spy talk for assassinations). After the election of Jimmy Carter, this group was erased from the books and hidden in private companies, and Shackley was the man in charge of the unit both in and out of government. The program was divided into different components. CIA man William Buckley supposedly had directed one out of Mexico with Quintero and Ricardo Chavez. Another unit was headed by a former Mossad officer. Felix Rodriguez was involved in yet one more in the Mideast. Sheehan took Wilson at his word. "Wilson went into such detail," Sheehan later maintained. "It's not something that's being made up."
