Haggai Carmon heads Carmon & Carmon, an international law firm with an intelligence gathering/asset recovery arm called GLOBALAW. In 1985, the U.S. Justice Department started retaining Carmon as its attorney to represent the government's interests in its Israeli civil litigation matters, a task he continues to perform. Carmon is also the legal counsel to the U.S. Embassy in Tel Aviv, and in 2007, he successfully represented the European Union in civil litigation cases in Israel. He also represents business entities with transnational interests.

The thrillers that Haggai Carmon authors are inspired by the sensitive undercover work he performed for two decades. The U.S. Department of Justice and other government agencies assigned him with the worldwide responsibility (except for the U.S.) for gathering intelligence in complex multi-million dollar, white-collar money laundering and mega fraud cases that required work in more than thirty countries. Haggai Carmon is married to Rakeffet his law partner. They have five children and live in New York and Israel.
