A reader is commonly excited by a friendship between great authors. If only one could have eavesdropped on the conversations of Nathaniel Hawthorne and Herman Melville. Or to have been a fly on the wall in Geneva, as Lord Byron and Shelley chatted the night away (Percy Shelley, that is—Mary Shelley maintained a polite dislike for the Don Juan poet). These friendships, naturally, have perished with their authors. But that does not mean our age is without its own. One of today’s most remarkable literary alliances is to be found in the friendship between novelists Kazuo Ishiguro and Caryl Phillips.
