For thirty years, Hamish de Bretton-Gordon has served in conflict zones around the world. As the army's foremost chemical weapons expert, he built a unique first-hand understanding of how to prevent and respond to attacks - saving countless lives in the process.

Now updated to include the new frontier of Ukraine - where Hamish advises the government, NGOs and journalists on chemical defence - this is a soldier's story of bravery and survival against the odds.
