Heat butter or margarine in a medium-sized saucepan; blend in flour; cook 1 minute. Gradually add cream or milk, stirring as adding. Cook slowly, stirring, until thickened and smooth. Mix in cayenne, salt, pepper, and cheese. Cook slowly until cheese melts. Put each toast slice in a small oven-proof dish or place them all on a cookie sheet. Top each with a slice of chicken and 1/4 of the sauce. Top each with 2 slices bacon and 1 tablespoon grated cheese. Put under preheated broiler about 5 minutes until bubbly and golden.
