Out of a wickedly imagined version of MI5, [Herron] has spun works of diabolical plotting and high-spirited cynicism, their pages filled with sardonic wit, their characters approaching the surreal . . . Mr. Herron goes about this with bouncing black humor and a set of characters whose appearance and manner would be over the top in any other era. Happily for Mr. Herron—if alas for us—events continue to produce rich material for his special gifts, and we hope he is scribbling away making good use of it all.
