"A truly compelling contemporary spy thriller."
Morning Spy, Evening Spy
"[A] richly drawn, splendidly written novel of character....If you're a thriller reader, snatch this one up. It's the best of the year, by far."
St. Louis Post-Dispatch
"... moves with an unusually sure hand. It helps that the author, an American journalist who has worked in Iran, is writing about something of which he has had personal experience. Mr. MacKinnon clearly has a decent acquaintance with the spy novels of John le Carre and has even looked back to such masterpieces as Eric Ambler's 'Coffin for Dimitrios.' But he remains very much his own man and has written a most satisfactory thriller."
