Yes, now, Bertie will only be fashionably late. Once again, thank you for pointing me in the right direction with these prompts. I got two books from the library, one on American style in the 1920's and one on Art Deco and that's where I saw a photo of the clock. So, first, phantom night club, second, mysterious clock, and third...I wish I knew!

The gallery owner! He would definitely be in NYC in the 1920's.
