The Fist of God is a 1994 suspense novel by British writer Frederick Forsyth, with a fictitious retelling of the Iraqi Project Babylon and the resulting "supergun". Featuring a story set during the Persian Gulf War, the novel details an Allied effort to find the suspected Iraqi nuclear weapon. The story features the brothers Mike and Terry Martin who also appear in Forsyth's 2006 novel The Afghan. Plot Dr. Gerald Bull designs a supergun codenamed Project Babylon for Iraq. He believes that it is for launching satellites into space and assumes it could serve no military purpose for a few reasons: firstly, it cannot traverse from side to side, nor alter its angle of elevation or depression; secondly, it would have to be completely disassembled and reassembled to change targets, and lastly, it could fire only once before being located and destroyed. He comes to discover the true reason only shortly before being assassinated by his paymasters, though his death is variously blamed by the media on the Mossad, the Central Intelligence Agency, or any one of numerous other intelligence organisations. Iraq subsequently invades Kuwait, leading the British and Americans to require top-level intelligence on the ground. Major Mike Martin of the Special Air Service (SAS) is seconded to SIS to collaborate with the Kuwaiti resistance. Not only does Major Martin speak fluent Arabic, but with his black hair and dark complexion, he can practically pass for an Arab. His brother, Terry, an expert in Arab military studies, works with the Medusa Committee, a joint British-American panel investigating Iraq's weapons of mass destruction. The CIA and SIS do not have any assets deep inside the Iraqi government and the Mossad also initially deny they have any active agents within Iraq. However, they are forced later to admit they have an unidentified top agent, codenamed "Jericho", whom they have been paying for information on the Iraqi military and government through an account in Vienna, but from whom they have not heard since the invasion began. Because Israel is forced to stay out of the war to prevent alienating Arab countries in the Coalition, they agree to let the Americans run Jericho, if they can find him. Mike Martin is recalled from Kuwait and sent into Iraq to run Jericho through a series of dead drops while working a cover job as a house gardener for the Soviet Union's First Secretary to
