Best one in the series.
Too many crooks spoil the plot

A tangled mess with a private security firm, US mercs working for a foreign security agency, Iranian nut jobs working for the same agency and a Russian hit squad helped by a high-level CIA staffer combine to create a number of convoluted storylines. Add in a health-compromised Grey Man who miraculously functions at full health as the book nears its conclusion. And, who takes an elevator to exit a hotel when a fire alarm goes off?
Amazing as always.

Amazing as always. Love the parallel story lines. The vulnerabilities built in to the Grey man so he isn’t Superman.
Best in the series

Greary and Gray man are a magnificent as always. Scarily the plots are becoming of possibilities all too real in today’s world. The evilness of men…and women, are far too relatable in this battle of good vs evil.
Action packed
