This book covers a unique period in Canadian history when the country had four prime ministers over the course of five years after Sir John A. MacDonald died. While most people would know little about the four men today, each was very accomplished in their chosen fields before becoming prime minister and impacted the early days of Canada in their own way. The first chapter covers MacDonald's last years, giving context for the years 1891-96. I found the chapter on Abbott very interesting since, like me, he was an Anglophone Montrealer and I could connect with many of the places and situations described. Thompson was the prime minister that is tagged with the title of "what could have been." He was the consensus successor to MacDonald, but Abbott was chosen as a sort of placeholder until Thompson was ready. But after only two years in office, Thompson died suddenly at the age of 50, leaving his potential unfulfilled. Bowell and Tupper were once again placeholders in some sense. Bowell was a lifelong politician who was more comfortable behind the scenes than in leadership, and ended up being squeezed out by his own party. Tupper was a Father of Confederation who in his 70s was probably past his prime, and would have made a great prime minister a decade earlier. He eventually lost the 1896 election to Wilfrid Laurier, whose ascendancy and work is covered briefly in the last chapter. A good biography tells the story not only of the subject but of the times they live in. This book succeeds by telling the story of Canada in it's early years through the story of these four men. Very interesting and accessible book, not overly academic.
