Not a doorbell camera.

A real system — every common room, every entrance, every hallway, every exterior access point, all of it recorded continuously and backed up automatically to encrypted cloud storage that no one in that apartment could reach, alter, or delete.

I had installed it to keep strangers out.

It had never once occurred to me that the people I would one day need it to record were my own mother and sister.

My family believed they had stolen thirty-eight thousand dollars from a man too far away and too trusting to notice.

What they had actually done — what they had, in effect, purchased, with every dollar of it — was the most complete, time-stamped, encrypted, court-admissible package of evidence against themselves that a professional could possibly have wished for.
