Book excerpt: In Dark Diversions, acclaimed author John Ralston Saul stages a black comedy of international proportions that takes the reader from New York to Paris to Morocco to Haiti. When he's not encountering dictators in Third World hot spots, Saul's unnamed journalist narrator moves in privileged circles on both sides of the Atlantic, insinuating himself into the lives of well-to-do aristocrats. Through his exploits we experience a fascinating world of secret lovers, exiled princesses, death by veganism, and religious heresies. The emotional fireworks of these inhabitants of the First World are sharply juxtaposed with the political infighting of the dictators and the corruption, double-dealing, and fawning that attend them. But as he becomes further enmeshed in these worlds, the outsider status of the narrator grows more ambiguous: Is he a documentarian of privileged foibles and fundamental inequity, or an embodiment of the very "dark diversions" he chronicles?
