<I>The Cats of Copenhagen </I>was first written for James Joyce’s most beloved audience, his only grandson, Stephen James Joyce, and sent in a letter dated September 5, 1936. Cats were clearly a common currency between Joyce and his grandson. In early August 1936, Joyce sent Stephen “a little cat filled with sweets”—a kind of Trojan cat meant to outwit grown-ups. A few weeks later, Joyce penned a letter from Copenhagen that begins “Alas! I cannot send you a Copenhagen cat because there are no cats in Copenhagen.” The letter reveals the modernist master at his most playful, yet Joyce’s Copenhagen has a keen, anti-authoritarian quality that transcends the mere whimsy of a children’s story. Only recently rediscovered, this marks the inaugural U.S. publication of <I>The Cats of Copenhagen, </I>a treasure for readers of all ages. A rare addition to Joyce’s known body of work, it is a joy to see this exquisite story in print at last.
