Jiles is the creator and narrator behind This Is Monsters, a true crime production that investigates the darkest corners of human behavior through documentary-style storytelling. He structures his series into thematic seasons, such as Child Killers and Family Annihilators Part 2, focusing on the historical and psychological profiles of serial predators. Jiles recently launched Somewhere Sinister, a companion show that serves as his primary narrative outlet while transitioning away from previous projects. His work frequently critiques social issues, evident in his refusal to censor descriptions of victims' experiences and his vocal stances on issues like gun control and reproductive rights. In addition to long-form audio, he maintains a secondary YouTube channel called Jiles with a J where he produces more personal vlog-style content. This multifaceted approach is complemented by limited-run merchandise drops on his official website and collaborations with platforms like Gammatime for exclusive true crime features.
