Alistair MacLean vs. Agatha Christie

At first glance, there seem to be few similarities between the fast-paced thrillers of Alistair MacLean and the (not quite) cosy mysteries of Agatha Christie. Yet their novels sometimes explore similar themes. During the Cold War, both writers tapped into widespread fears about science, atomic weapons, espionage, and ideological conflict, producing stories where secrecy and science threaten humanity itself.

MacLean’s 'The Satan Bug' (1962) and Christie’s 'Destination Unknown' (1954) share remarkably similar territory. Both revolve around the dangerous liaison of science and secrecy, a heady combination governments invariably claim to control right up to the almost inevitable moment when everything goes haywire.

In 'The Satan Bug', deadly biological agents are stolen from Mordon* Microbiological Research Establishment, a supposedly impregnable British laboratory, proving once again that 'top secret' usually means 'just one mistake away from disaster'. The theft of the Satan Bug triggers a frantic investigation led by security expert Pierre Cavell. The novel combines high-stakes action with fears of apocalyptic scientific power. Alistair MacLean explores the familiar reality that humans are often less reliable than the weapons they invent.

Christie’s 'Destination Unknown' takes a somewhat quieter but equally sceptical approach. Scientists vanish across the world, lured or coerced into a secret research facility, hidden in the Atlas Mountains that is disguised as a leper colony. Hilary Craven, a grieving woman with little left to lose, is recruited by British intelligence and infiltrates the settlement. There, those brilliant minds are gathered in isolation, raising unsettling questions about scientific ethics and coercion. Agatha Christie gently dismantles the comforting albeit gullible belief that brilliant minds will mostly produce something positive. Intelligence, in both novels, is shown as morally flexible and alarmingly easy to weaponise.

A major similarity between the novels is their use of isolated strongholds, a literary concept known as heterotopic spaces. Both MacLean and Christie use these sealed worlds cut off from society where scientific idealism is manipulated and controlled. Both settings intensify tension while reflecting Cold War anxieties about biological warfare and atomic secrets.

Espionage and human vulnerability also connect the two stories. Alistair MacLean’s protagonist struggles with betrayal and moral conflict amid relentless action, while Agatha Christie’s 'protagonix' begins her venture in despair after personal tragedy before finding purpose in a dangerous undercover mission. Both authors try to put a human face on global political threats through emotionally vulnerable protagonists.

Obviously, the authors differ greatly stylistically. Alistair MacLean relies on pace, danger, and physical action, while Agatha Christie emphasizes psychological tension and deduction. Yet both successfully blend detective fiction with the spy thriller.

Both novels do capture the mid-last century fears about science becoming a sort of modern Pandora’s box. Add to that the looming threat of the atomic bomb, and you can imagine the almost collective anxiety that pervaded society. Even today, in an age still concerned with war, lab leaks, and technological secrecy, both books remain remarkably relevant.

* I wonder whether Alistair MacLean had read 'The Lord of the Rings', given the conspicuous similarity between 'Mordon' and 'Mordor,' the shadowy realm of the Dark Lord Sauron.
