September is coming in like a lion, bringing with it a rush of news. Yesterday, Matt Chaban penned an update in the Times on the doings at River House that this reporter has been covering in Avenue for several years. His big scoop: board president John Allison, architect of the building’s new glasnost policy, has listed his own apartment. And the September issue of Avenue, where I’m guest editor while Daisy Prince is on maternity leave, is now live online. My latest Unreal Estate column concerns the sale of a townhouse long occupied by Ashraf Pahlavi, the twin sister of the former Shah of Iran. And you’ll probably want to check out Avenue’s list of the 25 Sexiest New Yorkers.
