Anything Steinhauer writes is usually spun gold; this time, he weaves it differently, with strands of differing viewpoints and multiple characters starting at various time points in the story and at differing locations. Other than the opening (he never should have started with the Chinese thread there) it mostly works.
Milo Weaver, and his sister, is a gem.
I will miss Evgeny Primakov.
Letitia should be granted her own series.
