It's possible that:
* The name is misspelled: Perhaps you're thinking of a similar-sounding name, like Basil de Selincourt, Basil Davenport, or another author.
* The author is less known: The author may have published under a pseudonym or written in a niche genre.
Please provide more context or information about the author, such as any books you remember them writing or the genre of their work. This will help me find the correct author and provide a better answer.
