Blood and Sacrament: A Chronicle of Colonial Horror Summary: Manila, 1840. When journalist Don Eduardo Santos is assigned to cover the execution of Juan Severino Mallari—the first Filipino Catholic priest condemned to hang—he expects to document a simple criminal case. Instead, he uncovers a decade of systematic horror that challenges everything he believes about faith, civilization, and human nature. Mallari stands accused of murdering fifty-seven parishioners in remote Pampanga, but Santos's investigation reveals crimes that transcend ordinary evil. Through interviews with survivors, examination of suppressed church records, and conversations with the condemned priest himself, Santos discovers that Mallari transformed Catholic ritual into instruments of systematic slaughter, conducting murders within the sacred framework of Mass while maintaining perfect orthodoxy. As Santos delves deeper into the case, he uncovers a network of corresponding priests applying similar methods across the archipelago, communities that participated in victim selection, and theological innovations that synthesize Catholic doctrine with pre-Christian Filipino spirituality. The investigation reveals not isolated madness but organized religious movement that challenges Spanish colonial authority and Catholic orthodoxy. Structured as a gothic investigation across twenty-eight chapters, this historical horror novel explores the collision between European colonialism and indigenous beliefs, the corruption of religious authority, and the terrible consequences when love becomes indistinguishable from evil. Based on the true crimes of history's most notorious Filipino priest.
