Luis Zapata's best known work is El vampiro de la colonia Roma (1979). The English translation (1981) is Adonis Garcia, A Picaresque Novel. I enjoyed it a lot.
Years later, I had Kieran get Zapata to inscribe a Spanish language copy of the book for Victor. I gave the book to Victor. He read it, then quickly lent it to an acquaintance, and it never came back. I was unhappy about losing an autographed book.
