According to Mathew
The story of a socially popular, powerful, and highly respected Protestant priest of St Pauls Church in Colombo, and sought after Exorcist, Father Matthew Peries, who in the late 1970s, conspired with his mistress, to murder his wife and the mistress’s husband, by poisoning the victims with gradual overdoses of insulin. He evaded detection owing to his standing in the community and continued fearlessly with his nefarious activities.
