In 1949, Frank Weeks, fair-haired boy of the newly formed CIA, was exposed as a Communist spy and vanished behind the Iron Curtain. Now, twelve years later, he has written his memoirs, a KGB-approved project almost certain to be an international bestseller, and has asked his brother, Simon, a publisher, to come to Moscow to edit the manuscript. It's a reunion Simon both dreads and longs for. The book is sure to be filled with mischief and misinformation, Frank's motives suspect, the CIA hostile. But the chance to see Frank, his adored older brother, proves irresistible. And at first Frank is still Frank--the same charm, the same jokes, the same bond of affection that transcends ideology. Then Simon begins to glimpse another Frank, still capable of treachery, still actively working for "the Service." Pulled into Frank's twilit world, he finds himself caught between the KGB and the CIA in a fatal scheme that pits the brothers against each other, like scorpions in a bottle, safe unless one of them attacks. But one always does.
