Let George Do It - Big Brother

George Valentine receives a letter that reads "My dear Mr. Valentine, my name is Lou Mendel. I own a nightclub, the Club Top Hat, which I'm sure if you've ever been there, you'll admit is a very high class place. It's not the type place where we have any trouble, and everything is strictly above the board, which is where you fit into the picture puzzle, Mr. Valentine. There is this girl whose name is Dove. She's a new dancer on account of she can't dance, but I like to be big-hearted. But as of today, my big heart has got me nothing but a blow on the head. This is the essence of the puzzle. Who hit me? Even more important is what about Dove? She is somehow in the middle of the trouble, and for such a nice girl, I don't like it. Oh yes, this is a lot more than just what you may be thinking, because poor little Dove, you understand, looks upon me as her big brother". George and Brooksie make the trip to the Club Top Hat. In their meeting, Brooksie asks "And how do you look upon her, Mr. Mendel?" He says "What's the matter with me? You think I'm inhuman?" George says "Well, if she was the third girl from the left, I'd say..." Mendel says "Never mind, never mind. You'd say the wrong things anyway. To me, she's nothing, except I think I should help". George says "You think she's in trouble?" Mendel says "I do not think very much, but there are some things I know. Oh, here, here. Dressing rooms are down this way". As they are going toward the dressing rooms, they encounter a man named Andrew holding a bouquet of flowers. He sees them and says "Oh, hello". Mendel says "Oh, good evening, sir. I think perhaps you're in the wrong place. If you were looking for the check room or the... " Brooksie says "Oh, no, he's not, Mr. Mendel. Oh, what beautiful flowers". Andrew says "Oh, yes. Thank you. I'm sorry I was in your way. I'm just waiting, that's all". George says "Not at all. Haven't I seen you someplace before?"  Andrew says "Oh, no, sir. No, I'm quite certain. No, sir". Mendel says "Stage Door Johnny".
