61 HOURS by Lee Child

The household got right back into its settled routine. Peterson left, and the two day watch women went up to bed. Janet Salter showed Reacher to the front upstairs room with the window over the porch roof. In principle the most vulnerable, but he wasn't worried. Sheer rage would overcome any theoretical tactical disadvantage. He hated to be woken in the night. An intruder came through that window, he would go straight back out like a spear.

Five to two in the morning.

Twenty-six hours to go.
