Random House tumbled on the secret of perennial sales in the 1960s and 1970s when Truman Capote's slender and sentimental "A Christmas Memory" continued to fly off the shelves year after year. "The Christmas Box" by Richard Paul Evans has returned annually like wild mistletoe since it was published in the mid-1990s. (But that's a case of an obscure writer happening upon bestsellerdom, not a bestselling author setting out to conquer the world.)
