Excerpt
 
The old man sits on the edge of the narrow bed, palms spread out on his knees, head down, staring at the floor. He has no idea that a camera is planted in the ceiling directly above him. The shutter clicks silently once every second, producing eighty-six thousand four hundred still photos with each revolution of the earth. Even if he knew he was being watched, it wouldn't make any difference. His mind is elsewhere, stranded among the figments in his head as he searches for an answer to the question that haunts him.
 
Who is he? What is he doing here? When did he arrive and how long will he remain? With any luck, time will tell us all. For the moment, our only task is to study the pictures as attentively as we can and refrain from drawing any premature conclusions.
 
There are a number of objects in the room, and on each one a strip of white tape has been affixed to the surface, bearing a single word written out in block letters. On the bedside table, for example, the word is table. On the lamp, the word is lamp. Even on the wall, which is not strictly speaking an object, there is a strip of tape that reads wall. The old man looks up for a moment, sees the wall, sees the strip of tape attached to the wall, and pronounces the word wall in a soft voice. What cannot be known at this point is whether he is reading the word on the strip of tape or simply referring to the wall itself. It could be that he has forgotten how to read but still recognizes things for what they are and can call them by their names, or, conversely, that he has lost the ability to recognize things for what they are but still knows how to read.
 
He is dressed in blue-and-yellow striped cotton pajamas, and his feet are encased in a pair of black leather slippers. It is unclear to him exactly where he is. In the room, yes, but in what building is the room located? In a house? In a hospital? In a prison? He can't remember how long he has been here or the nature of the circumstances that precipitated his removal to this place. Perhaps he has always been here; perhaps this is where he has lived since the day he was born. What he knows is that his heart is filled with an implacable sense of guilt. At the same time, he can't escape the feeling that he is the victim of a terrible injustice.
 
There is one window in the room, but the shade is drawn, and as far as he can remember he has not yet looked out of it. Likewise with the door and its white porcelain knob. Is he locked in, or is he free to come and go as he wishes? He has yet to investigate this matter--for, as stated in the first paragraph above, his mind is elsewhere, adrift in the past as he wanders among the phantom beings that clutter his head, struggling to answer the question that haunts him.
 
The pictures do not lie, but neither do they tell the whole story. They are merely a record of time passing, the outward evidence. The old man's age, for example, is difficult to determine from the slightly out-of-focus black-and-white images. The only fact that can be set down with any certainty is that he is not young, but the word old is a flexible term and can be used to describe a person anywhere between sixty and a hundred. We will therefore drop the epithet old man and henceforth refer to the person in the room as Mr. Blank. For the time being, no first name will be necessary.
 
Mr. Blank stands up from the bed at last, pauses briefly to steady his balance, and then shuffles over to the desk at the other end of the room. He feels tired, as if he has just wok
