Horwitz the Star Sleuth
It occurred to Horwitz that his adopted home of Manhattan—with its crowded sidewalks and proletarian taxis—was a better hunting ground: All that was missing was a proper map. Collecting newspaper clips, debriefing deliverymen and chatting up doormen, he homed in on 384 celebs. The result is the (pseudonymic) Larry Wolfe's Official Map of Movie Stars' Homes in New York City—a document that pinpoints luminaries of all stripes, including Calvin Klein, Demi Moore, Kathleen Turner and JFK Jr.
According to Horwitz, many celebs favor Fifth Avenue or Central Park West, which offer stunning views of Central Park. But mavericks like Robert De Niro give downtown its hip cachet, as do Cher, Keith Richards and Rob Lowe, who all live in the same building.
Author of a satirical paperback called Over 101 Uses for a Dead Husband: An Owner's Manual, Horwitz, 36, lives on the Upper East Side with girlfriend Dana Ring, 24, an advertising exec. A political science major at Ontario's York University, he ran an unsuccessful campaign for city council there when he was just 21. Mapmaking, however, seems to be his true calling; while he claims he has received no complaints from stars who appear on his map, he says he's been scolded by some who were omitted.
Although Horwitz asks star-stalkers to respect their prey's privacy, those on the map are unlikely to welcome the $3.95 guide. "People pursuing inappropriate encounters have a far higher likelihood of success as a result of'Mr. Wolfe,' " says L.A. security consultant Gavin de Becker. Retorts Horwitz: "Most stars have elaborate security systems in their buildings. Some even have private security guards or bodyguards. I think the threat is remote."
