i was told (at my bookclub) there'd be an HBO series...

Oh yeah, here are those other Sloane-y bits I was talking about:

According to a NY Observer article from June:

TV rights for I Was Told There'd Be Cake, the best-selling essay collection by Vintage publicist Sloane Crosley, have been sold to HBO for series development. This according to an announcement posted on the Publisher's Marketplace bulletin board over the weekend.

Also, the details on that Sloane diorama is over at Gawker, and it looks like they feature everyone's favorite essay about a bathroom mystery.
