In the tradition of classic crime fiction writers, we use a pen name, C.M. West.
For example, Ellery Queen is a crime fiction pseudonym by Frederic Dannay and Manfred Bennington Lee, from 1929. Incidentally, those authors names are also penned and not their real names. Together as author Ellery Queen, they wrote novels and short stories involving a brilliant amateur detective, also named Ellery Queen.
