Doctor Who is the world's longest running science fiction television series. Each handbook provides both a broad overview and a detailed analysis of one phase of the programme's history. With the ground-breaking changeover from William Hartnell to Patrick Troughton, Doctor Who demonstrated that it could survive even the departure of the leading actor. Troughton's introduction energised the show, giving it a new lease of life. The writers also introduced or developed some of the show's most enduring characters: the resourceful Jamie McCrimmon and the orphaned Victoria Waterfield, companions who shared our screens with the Doctor's greatest enemies—the emotionless Cybermen, the militaristic Ice Warriors, the robotic Yeti and, of course, the Daleks. This book is an in in-depth study of Patrick Troughton's tenure as the Doctor, including a profile of the actor, a critical summary of each story in which he starred, an extensive feature on the making of The Mind Robber—a classic adventure set in the deadly Land of Fiction—and much more. The authors have established their reputation with best-selling books such as The Sixties and The Seventies, and their acclaimed work on other books in the Handbook range." — From the back cover of the first edition
