Is there a good game for the spy/espionage genre? Either one aimed at that or easily adaptable to it. There's Deniable, but it's a more satirical and humorous take on the genre. What other options are out there?

A key part of the question got left out and the reason Deniable's mentioned: it ought to read "Is there a good PbtA game for the spy/espionage genre?" We have lots of good options outside (as witnessed by the great suggestions), but what pbtA would work?
