No Safe House

The witness died on a Thursday, in a house that was supposed to be invisible. Safe house Fourteen was a two-storey colonial in a residential neighbourhood in Bucaramanga, indistinguishable from its neighbours except for the reinforced door frames and the panic room behind the master bedroom closet. Daniela Mora had placed the witness there herself, using the standard protocol — randomized selection from the available inventory, need-to-know access, encrypted communication channels, the works. The witness, a former cartel accountant named Perez, had been in the house for eleven days. He had followed the rules. He had not contacted anyone. He had not left the property. He had done everything right, and now he was dead, shot once through the kitchen window by a round that the forensics team said was fired from the roof of the apartment building across the street — a building that offered a clean line of sight to exactly one window in the house. The shooter had known which window to watch.

Daniela stood in the kitchen and looked at the broken glass and the blood on the tile floor and ran the numbers in her head. She managed nineteen witnesses across eight safe houses. The locations were stored in a system with three layers of encryption, accessible only to her and her direct superior, Director Castillo. The address selection was randomized by an algorithm that even Daniela couldnot predict. The odds of someone identifying Safe House Fourteen through surveillance alone were, by her calculation, effectively zero. Which meant the location had been leaked. Which meant the system — the system she had built, the system she had trusted with nineteen lives — was compromised.

She reported the breach to Castillo within the hour. He listened, expressed appropriate concern, and authorized an investigation. He also told her not to move the remaining witnesses until the investigation identified the source of the leak. This was, by any standard of witness protection, insane. Daniela told him so. He told her that moving nineteen witnesses simultaneously would attract attention and that attention was the enemy of security. His logic was sound. His logic was also, Daniela noted, exactly the logic you would use if you wanted the witnesses to stay exactly where they were.
