Reacher is on a late-night Philadelphia subway when a woman across the carriage catches his attention. She is distressed, watching him with the kind of intensity that means something is about to happen. She pulls a gun. Seconds later she is dead, and Reacher is interrogated by cops who insist she took her own life.

He doesn't believe it. Her brother confirms what Reacher already suspects: she would never have killed herself. There is also a hard drive that extremely dangerous people are determined to recover. Lila Hoth arrives with her mother Amisha, tracking down an international connection to a deep-state conspiracy.

What starts as a woman's death on a subway becomes international terrorism, buried secrets, and a conspiracy reaching into places Reacher didn't know to look. Based on Lee Child's Gone Tomorrow, this season plays like a spy thriller more than anything Reacher has tackled before.
