Unlike most public servants, top administrators – those who manage thousands of personnel and oversee millions of dollars in public spending – are appointed by the head of government.

At the Pleasure of the Crown is a detailed exploration of this central but overlooked aspect of governing. Using an impressive array of quantitative and qualitative data, Christopher A.
