Here is the Rome of the Popes, of a poet who loathed priests - Shelley, his wife and their son - in happiness and in tragedy. Here too are the city's intimitable railways, its innumerable cats. Sheridan the historian unravels the curious story of Mussloini's son-in-law and the British ambassador and as befits his period as a leading newspaper correspondent, new thoughts on Don Giulio Andreotti, seven times Prime Minister, as well as the Moro and Calvi affairs and other scandals.
