It is often regarded that El clavo (1853; The Nail and other Tales of Mystery and Crime) by Pedro Antonio de Alarcón y Ariza (1833 – 1891) is Spain’s first mystery story. It was written 12 years after Edgar Allan Poe published The Murders in the Rue Morgue (1841). During the rest of the 19th century and the early years of the 20th, mystery stories didn’t had many followers, with some exceptions, like La incógnita (1889; The Unknown) by Benito Pérez Galdós (1843 – 1920), and La gota de sangre (1911; A Drop of Blood) by Emilia Pardo-Bazán Condesa de Pardo Bazán (1852 – 1921) who penned, in addition, other short stories related to the genre. Shortly I look forward to read and comment some of these stories and, hopefully, read the stories of other authors like Joaquin Belda and A. Fernández Arias, whose works may be quite difficult to find. Although this is a long term project.
If you know about other authors and/or works in the genre written by Spanish authors before 1920, I’m particularly interested on the subject and I’ll appreciate any details in the comments.
