H. G. Carrillo was a writer’s writer—not a household name, but esteemed in literary circles. He began writing later in life, and was in his mid-forties when his first novel, “Loosing My Espanish,” was published. The book, which describes a Cuban-immigrant experience, was hailed as a triumph of Latino fiction; Junot Díaz praised the author’s “formidable” talent, calling his “lyricism pitch-perfect and his compassion limitless.” Carrillo went on to literary positions in and outside of the academy. He was an early casualty of the COVID pandemic, dying in the spring of 2020 at the age of fifty-nine. But his obituary—instead of tying a bow on the historical record—unspooled in quite a different direction, revealing secrets that Carrillo had worked for decades to conceal. For two years, the staff writer D. T. Max has been trying to trace what happened, and why.
