He had a BlackBerry, an iPad, an iPod, and a third-generation Kindle.He had a pain, mild but constant, a fluttery twinge in the soft tissue just above his left eye, deep in the hollow where you’d put your thumb if you were going to try lifting him by his cranium. Sometimes late at night, in his tiny apartment in a grimly forgotten, perpetually unfashionable corner of Lower Manhattan, he would find himself Googling: twinge, eye, flutter. Or: thumb, skull.When it occurred to him what that last pair rhymed with—numbskull—he stopped Googling it. But he couldn’t forget.Each weekday, Harold took the subway to his job at a video store a few blocks from Ground Zero, a place with a sale bin out front and a sputtery neon sign in the grimy window.
