Destination Unknown (novel)

Hilary Craven, a deserted wife and bereaved mother, is planning suicide in a Moroccan hotel. British secret agent Jessop picks the lock of her door to propose that she undertakes a dangerous mission as an alternative to taking an overdose of sleeping pills. The task, which she accepts, is to impersonate the wife of Thomas Betterton, a nuclear scientist who has disappeared and may have defected to the Soviet Union. Soon she finds herself in a group of oddly-assorted travellers being transported to the unknown destination of the title.

The destination is a secret scientific research facility disguised as a modern leper colony and medical research center at a remote location in the Atlas Mountains. The scientists are well-treated and supplied with all equipment needed for their research, but they are not allowed to leave the facility for any reason. They are locked in secret areas deep inside the Mountains whenever government officials and other outsiders visit. Hilary Craven successfully passes herself as Betterton's wife Olive, because he is miserable and wants desperately to escape. He says he cannot do his best work without freedom.

Hilary discovers that the facility was built by the fabulously wealthy and somewhat villainous Mr Aristides, for financial rather than political ends. He has lured many of the world's best young scientists to it with various deceptions so that he can later sell their services back to the world's governments and corporations for a huge profit. She falls in love with Andrew Peters, a handsome young American and a research chemist who travels in the group with her to the facility.

With the help of clues that Hilary has left along the route to the secret facility and local Berbers who find those clues for him, Jessop, with diplomats from nations losing young scientists, locates the facility, tours it, and breaks that wall of separation. Jessop rescues Hilary and the others held there. Peters proves to be Boris Glydr of Poland, using an assumed name and speaking American English. He is on a mission for his late cousin Elsa. He wants Betterton to face justice for the murder of his first wife, Glydr's cousin Elsa. Betterton is not a creative, world-class scientist, having fraudulently announced the discovery of ZE Fission as his own after plagiarising his wife Elsa's work. Betterton is arrested. Hilary no longer wants to die, rediscovering her desire to live; she and Peters are free to begin their life together.

This book explores the 1950s subject of defection to the Soviets, but it also demonstrates how the break-up of Christie's first marriage in the 1920s remained with her. Like her 1934 Mary Westmacott novel Unfinished Portrait, it starts with a youngish woman who has married, had a daughter and whose husband has replaced her with someone else.

In both books, a young man displays remarkable perceptiveness in spotting her intention to end her life and defies convention to save her, not only in tackling a stranger on intimate matters but in spending time in the woman's hotel bedroom to talk her out of suicide. In this story he talks her into espionage instead.

Philip John Stead writing in The Times Literary Supplement in its review of 19 November 1954, was enthusiastic about the novel in posing the question, "Where do scientists go when they vanish from the ken of the Security Services? A solution to this fascinating problem is propounded in Destination Unknown. While it must be admitted that the secret, when disclosed, smacks rather of The Thousand and One Nights than of modern international rivalry for scientific talents, it may surely be excused on the ground that it provides Mrs Christie with a story-tellers holiday from the rigours of detective fiction. Readers may regret the absence of the tonic logicalities of crime's unravelling – though "clues" are not altogether missing – for the secret service story belongs largely to Adventure, but in their place is the author's obvious pleasure in the wider horizons of the more romantic genre." The review concluded, "However much the purist yearns for Poirot or Miss Marple, he can hardly deplore Mrs Christie's bright, busy excursion into this topical and extravagant sphere."[4]

Maurice Richardson of The Observer of 31 October 1954, said, "The thriller is not Agatha Christie's forte; it makes her go all breathless and naïve." He concluded, "Needs to be read indulgently in a very comfortable railway carriage. She probably had a delicious busman's holiday writing it."[5]

Robert Barnard wrote, "Slightly above-average thriller, with excellent beginning (heroine, whose husband has left her for another woman, and whose small daughter had died, contemplates suicide in strange hotel). Thereafter topples over into hokum, with a notably unexciting climax. Mainly concerns disappearing scientists – it is written in the wake of the Fuchs/Pontecorvo affairs. Mentions the un-American Activities Committee, without obvious disapproval." Barnard refers to Bruno Pontecorvo, a pioneering nuclear scientist who worked with the Allies in World War II then defected to the Soviet Union in 1950 and Klaus Fuchs, theoretical physicist who was also in Los Alamos during World War II, but sent secret knowledge to the Soviet Union and went to prison for that in 1950.[6]
