Sometime after he had given up hope and then recovered it, Adolfo Davis began writing letters from his prison cell. Around 1999, he bought paper and pens from the commissary and wrote one letter after another, three times a week. He wrote on his bed, a squeaky metal frame with a lumpy loaf of a mattress, under the ugly glare of a fluorescent light bulb. There was nothing much to look at in his cell, just gray walls and a burnt-orange door made of steel, with tiny holes drilled through it. Muffled sounds from the hallway helped him figure out what time of day it was, when it was mealtime, which guards were working.
