Author Gigi Mahon Buys $10 M. Plaza Condo

The wife of former Citicorp vice chairman Thomas Theobald paid a little over $10 million for a condo at the Plaza. A Nov. 29 property deed lists Gigi Mahon, author of The Last Days of the New Yorker, as the buyer of Unit 501.

Mr. Theobald left Citicorp in 1987 and is now a senior adviser at the Chicago Growth Capital hedge fund. The couple put their $18 million Greenwich, Conn., home on the market in January.
