 You had access to the photograph album and only you. Oddly enough, Mr. Crail didn't even know his daughter had a birthmark until you told him. That may be true, but what of it? It's unimportant. Now I want to show you another picture. Archie, explain this picture, will you? Rating from left to right, this is a picture of Miss Crail's back. Very pretty, too. As you can see, there is what appears to be a small birthmark... ...somewhat under the left shoulder blade. I change focus...
