About The Shadow Friends
A Russian defector and disease expert dies mysteriously at a conference in Purity, Maine, followed by the murder of a hotel waitress. For retired CIA operative Ingrid Slocum, the clues echo a disastrous mission from three decades earlier. Drawn back into espionage by a former colleague and lover, she heads to Amsterdam in search of answers while Maggie Bird, Lloyd and the Martini Club race after her—and a network of assassins closes in.
