At a small British trade fair in Moscow, a message of global importance is made up of three very fragile human links: a Soviet physicist (code name Bluebird) burdened with a secret knowledge; a beautiful young Russian woman to whom the papers are entrusted; and Barley Blair, a bewildered English publisher pressed into service by British Intelligence to ferret out the source of the document. A magnificent story of love, betrayal, and courage. The Russia house catches history in the act.--Back cover.
