• The mystery buyer who paid $30 million for a penthouse at 145 Hudson Street—and who the New York Times described as "not an investment banker or the manager of a hedge fund"—is none other than convicted felon William Duker, the attorney (and now private investor) who was sentenced to 33 months in prison in 1997 for falsely inflating legal bills to the federal government.

The late William F. Buckley Jr., founder of the National Review, apparently believed that anyone with the bad manners to be conceived during an affair should suffer the consequences. His illegitimate grandson, Jonathan—the son of author Christopher Buckley and the result of his affair with book publicist Irina Woelfe—will not get a penny of his estate, worth tens of millions, reports the Post, after Buckley literally stated in his will that the child was dead to him: "I intentionally make no provision herein for said Jonathan, who for all purposes... shall be deemed to have predeceased me." The details have emerged because Woelfe is filing suit to seek more child support from Christopher, who she claims hasn't wanted to see their son.

• Late icon of conservatism William F. Buckley's duplex at 778 Park (also the last address of Brooke Astor) has gone on the market for $24.5 million. The 5,000-square-foot space (above) has four bedrooms, and 4.5 bathrooms; no extra charge for the lingering ghosts of Richard Nixon and Ronald Reagan. [Daily News, Barak Realty]
