My son came home acting strange, but it was his refusal to sit that led me to the police station.

On Sunday evenings in Phoenix, the desert heat never really disappeared, it simply thinned out and hovered above the asphalt as the sun slipped behind the mountains, leaving the sky streaked in dusty orange and fading violet as if the city were holding its breath before another long week began.

For Grant Ellison, Sundays were never relaxing, they were inspections of the most important part of his life.

At exactly 6:50 p.m., Grant steered his charcoal gray Range Rover through a worn neighborhood in South Phoenix where sagging porches and faded paint told quiet stories of strain and compromise, and even after three years of this routine, the contrast between this block and his glass walled home overlooking the desert in North Scottsdale still struck him with a force he never mentioned out loud.

This was where his son stayed every other week.
