Objects are apt to wander. I have found, though, that they tend to travel no more than eighteen inches from their original location. To the circle described by this eighteen-inch radius I have given a name. I call it the Eureka Zone. With the aid of a ruler (or a Eureka-Stik–click here for instructions on making one), determine the Eureka Zone of your lost object. Then explore it. Meticulously.Link
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
