Since escaping the fascist regime in Chile in the 1970s, Milton worked in the NHS for 40 years, specialising as an orthopaedic surgeon. He has campaigned tirelessly for safer patient care in hospitals, and in particular has called for legislation on nurse and midwife to patient ratios. He became a whistleblower in 2005, when his concerns over dangerous nurse staffing levels went ignored at Tameside Hospital, and The Flight of the Black Necked Swans combines his ongoing quest for more funding for the NHS with autobiographical details of his early life in Chile, and how a love of mountaineering and trekking has helped provide a balance in his life. A compelling read, an important book, and one we feel privileged to have worked on.
