The Memory Trap (1989) by Anthony Price. The nineteenth and last in an espionage series featuring Dr. David Audley, a British counter-intelligence agent. The story begins in the early days of Glasnost on the eve of a visit to London by Gorbachev. After a Russia defector, Oleg Kulik, is killed by a terrorist group in Berlin, Audley tries to unravel the threat by searching for a former colleague, Major Peter Richardson. An attempted meeting at Villa Jovis, the ruins of the palace of Tiberius on Capri, fails when Russian Colonel Zimin turns up instead. Both men suspect that General Lukianov is betraying his country by assisting Abu Nidal. Audley and his colleagues are next drawn to the the Cotswolds and eventually to Wales where memory, audacity, and luck prevent a major terrorist attack.
Anthony Price, who has been favorably compared to John le Carré, was recently described in a NYT obituary as “among several thriller writers who moved the espionage genre beyond the slick shenanigans of early-period James Bond as the Cold War calcified.” Unlike many contemporary espionage novels that feature action heroes, Price depicted the real world of intelligence driven by logic, information, and history.
In the fictional words of David Audley, “It all came down to memory. And not to damned computer-memory, which was no better than common coinage in the pockets of anyone who had access to it, but to private memory, which he alone possessed now.”
