Measuring time was next to impossible. No clocks, no sunlight, no signs from the outside world.

Smith had called out in his windowless cell, heard his voice echoed down the dingy corridor and yet there were no noises in response. No rumble of traffic, no coughing or shuffling of feet, no bellowing “to keep it down,” not even a crackle from the pipes or the creek of a floorboard. The silence outside was deafening and the only sounds Smith could hear were made by his own body.
