What is the Holcroft Covenant in the novel, The Holcroft Covenant?

The Holcroft Covenant is a plan hatched by a group of Nazis at the end of World War II, a written document with accompanying funds to act as directions to be carried out by their survivors. Seven hundred and eighty million dollars have been secreted in a Swiss bank by the time of the start of the novel, and these funds are only to be released when three selected members from the three Nazi families who drew up the agreement sign the release. To deceive the American branch of this group, the documents speak of using the funds to "make amends" for Holocaust survivors. In actuality, as the two European branches of this troika know, the real purpose is to restart the Nazi Reich through mobilizing the dispersed children of the Nazis.
