In his 1987 book "The Jesuits", Martin claims to prove the existence of a diplomatic agreement between the Vatican and the USSR called the Metz Accord. The Vatican allegedly promised non-condemnation of communism in exchange for participation of Russian-Orthodox prelates as observers at the Second Vatican Council. In his book "The Final Conclave", published on 1 August 1978, the month of the 1978 conclave that resulted in the 26 August election of Albino Luciani, Malachi Martin wrote of the unexpected election of a "Cardinal Angelico", a figure that has been interpreted as corresponding to Luciani.
