Step 1

Melt the butter or margarine over medium heat in a large saucepan or stockpot; add the onion, garlic, carrot, bay leaf, and thyme. Cook, stirring occasionally, until the onion softens. Add the lobster shells, and cook until they turn red.

Step 2

Add the wine and tomatoes. Bring to a gentle boil, and simmer for about 5 minutes. Add the stock and bring to a boil. Reduce the heat to medium, and simmer for 20 minutes.

Step 3

Remove the bay leaf. Remove the lobster shells; remove the meat from the shell, and set aside.

Step 4

Place the soup, in batches if necessary, in a blender or food processor; process until smooth. Return the soup to the pot, and bring to a boil. Add the cream and any lobster meat you may have, and heat through. Check for seasoning. Sprinkle with the parsley, and season with salt and pepper. Serve.
