A living man can be killed with a keystroke. Proving otherwise takes paper.
When a county correction batch harmonizes Caleb Ward to deceased - dead since 1985, though he stood at the clerk's counter last month - deputy clerk Katie Prentiss does the one thing the system never expects. She keeps the paper.
The registrar who signed Ward's death, a credential called A. Vale, has a name but no birthday, no office, no pulse. It was never born. It was generated - from an absence the machine mistook for authority.
Corbin Hale has seen this grammar before. Forty years ago, on a watch floor, he carried the pouches that taught a records system how to make a person disappear and call it hygiene. Now the same logic runs at 2:15 every morning, and it has reached a man he can still shake hands with.
To bring Caleb back, Hale and a county clerk, a tired lawyer, and a dying archivist's last message will have to do something no one has managed in four books: not destroy the record, not move it - interrupt it.
Dead Hand is the fourth Corbin Hale novel: a paper-trail conspiracy procedural in the le Carr tradition, where the most dangerous weapon is a rule that outlives the hand that wrote it.
