"As thrilling as le Carré gets . . . The novel has the heartstop duplicity of
A Perfect Spy and some of the outraged honor of
The Night Manager and
The Little Drummer Girl."
–The Boston Globe "Furious in action . . . takes us by the neck on page one and never lets go."
–Chicago Sun-Times "Irresistible . . . a sinuous plot, leisurely introduced, whose coils become increasingly constricting. There is crisp, intelligent dialogue, much of it riding an undercurrent of menace. And there is a hero who does not see himself as heroic but who struggles with inner demons as much as with the forces arrayed against him."
–Time "Gripping."
–The Christian Science Monitor
