Simon Chase's life is a maze of burner phones, encrypted emails, secret meetings, and weaponry - all devoted to executing missions too sensitive for government acknowledgement. Working for shadowy British and American organisations, Chase has been on the trail of Bin Laden in Afghanistan, protected allied generals in Iraq, and been part of an operation directly related to the attack in 2012 on the US consulate in Benghazi.

Zero Footprint takes us to this dangerous and thrilling world, and tells the true story of a private military contractor whose work forms the foundation for western security abroad, especially when the UK and US military, intelligence agencies, and departments of state need something done that they can't - or won't - do themselves.
