Two years before she died, Emily had put a small camera on a shelf in the living room so that she could see on her phone when Sophie got home from school on the days the sitter was late.

Nathan unplugged it.

Eight months before she died, packages started disappearing from the lobby of their building.

Three of Emily’s, and one belonging to a neighbor, over about six weeks.
