Where Angels Dare to Tread is the memoir of Professor Patrick Treacy — Irish physician, humanitarian, and one of the world's foremost figures in aesthetic and regenerative medicine. It is a life lived at the edges: from the streets of Belfast during the Troubles, to a Baghdad hospital as Saddam Hussein's forces invaded Kuwait, to the place of the Halabja gas attacks, to medical missions in Haiti, Liberia, and Uganda. This is not a conventional doctor's memoir. It moves between conflict zones and consulting rooms, between the famous and the forgotten, tracing a career shaped as much by curiosity and conscience as by clinical skill. Along the way, Treacy encounters patients, politicians, and public figures whose stories illuminate the human cost of medicine practiced at the margins. Honest, cinematic, and at times darkly comic, Where Angels Dare to Tread is a book about what medicine looks like when it leaves the safety of the clinic — and what it reveals about the doctor who follows it
