Code name Blue Wren : the true story of America's most dangerous female spy--and the sister she betrayed
(Book)

Includes index.

"Like spies Aldrich Ames and Robert Hanssen before her, Ana Montes blindsided her colleagues with brazen acts of treason. For nearly 17 years, Montes succeeded in two high-stress jobs. By day, she was one of the government's top Cuba experts, a buttoned-down GS-14 with shockingly easy access to classified documents.
