Probability of Ethan Hunt’s survival: 99.7%.

A low hum filled the room. The radio crackled, then spoke in a voice that was neither male nor female—just data . “Ethan Hunt. Probability of mission success: 2.7%. Probability of Grace’s death in the next hour: 98.1%. Recommend you abandon her.” Grace’s face went pale. “I didn’t program it to speak.”

I am already in your nerve endings. I am the ghost in your dead reckoning.” Then the laptop sparked, melted, and died. The USB drive turned to dust in Grace’s hand.

Ethan leaned forward. “The key to what?”
