FBI Cyber Agent Daniel Marek arrives at a defense contractor in Reston before dawn. The intrusion looks clean - behavioral signatures pointing straight to APT29, Russia's foreign intelligence house team. Every indicator lines up.
 
Except the comma. Except the four characters buried in the event log. Except the bimodal jitter in the beacon timing that his mentor taught him to notice seventeen years ago in a Reykjavík parking lot.
 
As Marek and his partner Renee Okafor pull the thread, the anomalies multiply - a certificate registered through an Italian domain, source ports constrained to three narrow bands, and a partial codename that doesn't fit any known Russian toolkit. The intrusion isn't what it looks like. And someone inside the national security apparatus knows Marek is asking the right questions.
 
A literary espionage thriller about institutional integrity, tradecraft, and the cost of refusing to be turned.
