A five-volume collection gathers short fiction, long narratives, essays, critical writings, and poems arranged with a preface, biographical sketch, notes and an index. It presents gothic and macabre tales that probe madness, doom, and uncanny atmosphere alongside foundational detective and ratiocination stories, adventurous hoaxes, and a sea narrative. The poetry moves between melancholic lyric pieces and highly musical, metrical experiments. Critical essays and reviews offer reflections on aesthetics, literary principles, and practical criticism. Taken together, the volumes map recurring concerns—imagination and terror, analytical deduction, and an ongoing preoccupation with beauty, loss, and musicality in language.
