During World War II, he worked for the British government as a soldier and a spy, first in East Africa for two years and then in Paris.
In the aftermath of the war, he converted to Christianity under the influence of Hugh Kingsmill and helped to bring Mother Teresa to popular attention in the West.
After graduating in 1924 with a pass degree in natural sciences, he went to British India for three years to teach English literature at Union Christian College, Aluva, Kingdom of Cochin.
His writing career began during his time in the Kingdom via an exchange of correspondence on war and peace with Mahatma Gandhi, with Muggeridge's article on the interactions being published in Young India, a local magazine.
During Muggeridge's early time in Moscow he was completing a novel, Picture Palace, loosely based on his experiences and observations at the Manchester Guardian.
Increasingly disillusioned by his close observation of communism in practice, Muggeridge decided to investigate reports of the famine in Ukraine by travelling there and to the Caucasus without first obtaining the permission of the Soviet authorities.
Having come into conflict with British newspapers' editorial policy of not provoking the authorities in the Soviet Union,[10] Muggeridge returned to novel writing.
He wrote Winter in Moscow (1934), which describes conditions in the "socialist utopia" and satirised Western journalists' uncritical view of the Soviet regime.
[14] Having spent two years as a Regimental Intelligence Officer in Britain, he was by 1942 in MI6 and had been posted to Lourenço Marques, the capital of Mozambique, as a bogus vice-consul (called a Special Correspondent by London Controlling Section).
[citation needed] After the Allied occupation of North Africa, he was posted to Algiers as liaison officer with the French sécurité militaire.
In that capacity, he was sent to Paris at the time of the liberation and worked alongside Charles de Gaulle's Free French Forces.
[21] Muggeridge ended the war as a major, having received the Croix de Guerre from the French government for undisclosed reasons.
He kept detailed diaries, which provide a vivid picture of the journalistic and political London of the day, including regular contact with George Orwell, Anthony Powell, Graham Greene and Bill Deedes; and he comments perceptively on Ian Fleming, Guy Burgess and Kim Philby.
It was little more than a rehash of views expressed in a 1955 article, Royal Soap Opera, but its timing caused outrage in the UK, and a contract with Beaverbrook Newspapers was cancelled.
[24] He was described as a "compulsive groper", reportedly being nicknamed "The Pouncer" and as "a man fully deserving of the acronym NSIT—not safe in taxis".
In contrast, he met the Beatles before they were famous: On 7 June 1961 he flew to Hamburg for an interview with the Stern magazine and afterwards went out on the town and ended up at the Top Ten Club on the Reeperbahn.
He used a sermon at St Giles' Cathedral in January 1968 to resign the post to protest against the Students' Representative Council's views on "pot and pills".
Agnostic for most of his life, Muggeridge became a Protestant Christian, publishing Jesus Rediscovered in 1969, a collection of essays, articles and sermons on faith, which became a best seller.
In A Third Testament, he profiles seven spiritual thinkers, whom he called "God's Spies", who influenced his life: Augustine of Hippo, William Blake, Blaise Pascal, Leo Tolstoy, Dietrich Bonhoeffer, Søren Kierkegaard, and Fyodor Dostoevsky.
[citation needed] Muggeridge became a leading figure in the Nationwide Festival of Light in 1971 protesting against the commercial exploitation of sex and violence in Britain and advocating the teaching of Christ as the key to recovering moral stability in the nation.
"[31] In 1979, along with Mervyn Stockwood, the Bishop of Southwark, Muggeridge appeared on the chat show Friday Night, Saturday Morning to discuss the film Life of Brian with Monty Python members John Cleese and Michael Palin.
Cleese said that his reputation had "plummeted" in his eyes, and Palin commented, "He was just being Muggeridge, preferring to have a very strong contrary opinion as opposed to none at all".
[citation needed] An eponymous literary society was established on 24 March 2003, the occasion of his centenary, and it publishes a quarterly newsletter, The Gargoyle.
In November 2008, on the 75th anniversary of the Ukraine famine, both Muggeridge and Gareth Jones were posthumously awarded the Ukrainian Order of Merit III Class to mark their exceptional services to the country and its people.
[38][39] In an interview on the Eric Metaxas Radio Show, notable Christian apologist Ravi Zacharias identified Malcolm Muggeridge and G. K. Chesterton as two important influencers in his life.
