A car accident in Japan.
A drowning in Seoul.
A home invasion in Boston.

Someone is killing the world s leading experts on robotics and artificial intelligence. Is it a tech company trying to eliminate the competition or something even more sinister? After all, AI may be the deadliest battlefield gamechanger since the creation of gunpowder.

Meanwhile, the quest for a quiet life has led the Gray Man to Central America, where he and his lover Zoya Zakharova have assumed new identities. Eventually, they re tracked down and offered a job by an old acquaintance of Zoya s: to extract a Russian scientist who is on the kill list. They reject it, but just being seen with him is enough to put assassins on their trail.

Now, they re back on the run, but no matter which way they turn, whoever s tracking them is always one step ahead. Since flight s no longer possible, fight is the only option left, and no one fights dirtier than the Gray Man.
