[3] Later, while living in the UK, he became concerned by the increasingly common portrayal of the widespread destitution and disease in his native Calcutta which stemmed from press reporting of the work of Mother Teresa.

[4]From the 1990s onwards he began to uncover what he calls a "cult of suffering"[3] which Mother Teresa and her followers in the Missionaries of Charity were running back in Calcutta supported by her friend Pope John Paul II.

[8] Chatterjee spent the next year travelling and interviewing people who had worked closely with Mother Teresa and the Missionaries of Charity and began to campaign against the conditions in Nirmal Hriday, also known as the Kalighat Home for the Dying in Calcutta.

"[13] Following the publication of his book, Chatterjee continued to speak out against what he calls the "bogus and fantastic figure" of Mother Teresa,[14] acting as Devil's advocate in the process of her sainthood.

[13] The book covers her life and her rise to fame following the documentary Something Beautiful for God by Malcolm Muggeridge, the Calcutta home for the dying and the practices of running it,[14] the non-consensual death bed baptisms of Hindus and Muslims,[15][16] the pathetic hygienic practices in the homes run by her,[17] her very limited connections with Kolkata and the masses[18] and the vast amount of financial donations given to the charity but not spent at Nirmal Hriday.

[19] He covers her Nobel Peace Prize and the speech in which she claimed to have saved tens of thousands of destitute people; Chatterjee estimates in his book the real number was 700.

[5] He also writes about the celebrities and the powerful people who had audiences with her, and the controversies surrounding the money she accepted from dictators such as Haitian president Jean-Claude Duvalier, convicted fraudster Charles Keating and disgraced publisher Robert Maxwell.

[17] The final chapters address her death, funeral and beatification and Chatterjee's own involvement as an official Devil's advocate or hostile witness and the transcripts of the proceedings.

[citation needed] Chatterjee sums up his view of Mother Teresa's life's work as: Principally, she was a ... medieval ideologue – who taught that abortion had to be banned at any cost.

[18] The Irish Times praised the content and advocated for its wide dissemination in light of its seriousness but noted Chatterjee's personal agenda to have undermined its credibility.

[27] Chatterjee pointed out the cure was a result of medical treatment Besra received from superintendent of the Balurghat Hospital and not the placing of metal jewellery on her body.
