The Cat Bastet is also my screen name or Nom de Clavier (Keyboard Name) on DorothyL, a discussion and idea mailing list for mystery lovers. Since one's nom is related to mystery stories, it adds an air of fun. According to the rules:
the nom may represent a person, either fictional or real, or an animal (e.g., Giant Rat of Sumatra) or a thing (e.g., Tailor Paul, a bell in Dorothy L. Sayers' The Nine Tailors) or a concept (e.g., The daughter of time, i.e., Truth from Elizabeth Tey's novel Daughter of Time) or even a word (e.g., the Latin word 'placet' by which Harriet Vane accepts Lord Peter Wimsey's proposal of marriage in Dorothy L. Sayers' Gaudy Night).
The name of a living person may NOT be chosen as a nom. You can choose to be known as Sir Arthur Conan Doyle or Dorothy L. Sayers or Ellis Peters, but NOT as Elizabeth Peters or Jan Burke or Sue Grafton or Sara Paretsky or Parnell Hall or Nancy Atherton. Only they are entitled to use their names, whether or not they are subscribed to DorothyL.
Those who know I wrote my Master's Thesis on Ellery Queen are probably wondering why I didn't use that as my screen name! Noms are limited to one person and someone already had Ellery Queen, so I had to choose another favorite character.
In case you don't know, Bastet was the cat-headed Egyptian goddess. So The Cat Bastet combines two of my hobbies: mysteries and Egyptology.
For those wondering why I didn't choose a Titanic-related name... come on, now. Would you want a screen name that means huge? I didn't think so!
