briefly lit up the church. He then was laid to rest in the Vatican grottoes. There are several conspiracy speculations related to his death. 2018 revelations The journalist and vice-postulator for John Paul I's cause of canonization, Stefania Falasca, published a new book in 2017 titled Pope Luciani, Chronicle of a Death, in which she revealed that John Paul I had complained of chest pains hours before his death, and the evening before, but paid no attention to it and ordered that his doctor not be called. Falasca confirmed, after interviewing the sisters who found him and documents from the Vatican Apostolic Archive, that John Paul I died of a heart attack in the late evening hours of 28 September 1978. The Cardinal Secretary of State Pietro Parolin, in his preface for the book, describes the various conspiracies regarding John Paul I's death as little more than "noir reconstructions". Parolin further says that the sudden death of the pope inspired "myriad theories, suspicions, [and] suppositions" based on opinion rather than fact. Falasca noted the 2009 testimony of Sister Margherita Marin, one of the two sisters who found the pope dead in his bedroom on the morning of 29 September 1978. John Paul I had made it a practice to have a morning coffee in the sacristy and then go into the chapel to pray before tending to the day's matters. Sister Vincenza had noted the pope had not touched the coffee she had left for him in the sacristy at 5:15 am (after about ten minutes) and went looking for him but found him dead, and hastily summoned Marin who also went into the room. Sister Vincenza said: "He hasn't come out yet? Why not?" and knocked a few more times but heard silence, then opened the door and walked in. Marin remained in the hallway but heard the elder sister say: "Your Holiness, you shouldn't pull these jokes on me" because Sister Vincenza also had heart problems. Marin testified that John Paul I's hands were cold, and she was struck by the darkness of his nails. Marin further testified that original information provided by the Vatican regarding who discovered the pope was wrong, since it had originally been claimed the discovery was by the pope's secretaries Lorenzi and Magee. Marin testified that "he was in bed with a slight smile" on his face. The reading light over the headboard
