Today if anyone needs reminding ,is Friday the thirteenth. The first since Edward Gorey author and illustrator died this April. Gorey wasn?t superstitious but was fascinated by the the macabre and the tradition of a day of terrible bad luck. Many of the ill-fated characters in his 100 books were the victims of freakish accidents. But Edward Gorey himself wasn?t gloomy or melancholy. He had many passions - perhaps the one least expected, was his love of the New York City Ballet. Judith Kampfner reports on this obsession.
