In the top of a double-boiler, melt the butter and flour together. Cook the mixture for 3-4 minutes for a blond roux. Stir in the onions, celery, and garlic. Season with salt, pepper, and mace. Cook the vegetables for 2 minutes. Whisk in the milk, cream, hot sauce, and Worcestershire. Bring the liquid up to a boil and reduce to a simmer. Simmer the soup for 15 minutes. Stir in the crab meat and continue simmering for 10-15 minutes. Reseason if necessary. Sprinkle the chopped eggs in the bottom of each bowl. Ladle the soup into each bowl. Drizzle the soup with the sherry. Garnish with chopped parsley.
