Chapter 25 - hollow walls

The words struck me like a physical blow, sending a wave of nausea through my stomach. I lowered the shotgun an inch, my mind racing through a maze of impossible questions.
"You're lying," I yelled back, my voice echoing off the high plaster ceilings.
"Ask your housekeeper where she was three nights ago," the voice sneered from the darkness of the foyer. "Ask her who paid her rent for three years while she lived in that dump on 4th Street.

On the dusty concrete floor, leading straight into the darkness, were two distinct sets of footprints: the small imprint of Nora's shoes, and beside them, the large, heavy tread of a man's combat boot.
