This is a memoir in the form of adventures of an itinerant pathologist from medical college to cancer research and teaching. The book takes the reader from the streets of the old city of London and St. Bartholomew's Hospital to medical schools and research centers in several European countries, Africa, Canada and the USA. Although autobiographical the emphasis of the story is found in the biographical sketches of the many fascinating characters encountered in this journey. All of the events are true, and although some of the individuals identities have been protected most are named; indeed they are truly part of my journey. Attempts have been made to describe diseases, their operations and autopsies in non-technical language expressing the excitement of discoveries particularly in cancer research and experimental treatments. This is not a treatise or a textbook but the life story of those who have devoted years to following in the footsteps of disease. The book is directed to all who are intrigued by new adventures, travel and the desire to have a deeper appreciation of body, mind and spirit.
