1. Slice mushrooms and sauté in 3 tablespoons butter. Add flour and salt and pepper to taste. Blend well. Stir in warm cream. Keep well heated.
2. In a separate skillet saute the filets in hot butter for 2-1/2 minutes per side (for rare).
3. Saute bread slices in 6 tablespoons butter, turning often to prevent butter from being absorbed. Arrange bread slices in a ring on well heated platter.
4. Top with the filets and arrange the mushroom sauce in the center. Stir the Scotch into pan juices, boil up for a minute or two and spoon sauce over the meat. Additional sauce can be passed separately.
