Robertson Davies is Canada’s leading writer—a master of plot intricacies and puzzles, one of the best storytellers in English-language literature. He made it onto the Booker shortlist and, late in life, was nearly awarded the Nobel Prize; yet even remaining a candidate forever, he gained the status of a world-class classic. His “Deptford Trilogy,” which marked the beginning of the “Canadian breakthrough” in world literature (“The Fifth Character,” “Manticore,” “The Book of Wonders”), is well known to Russian readers— and now it’s time for the “Cornish Trilogy.” It begins with “Rebel Angels,” continues with the novel “What’s Done in the Bones” (reaching the Booker shortlist), and concludes with “Lira of Orpheus.”
