Luke, Clive, Anton and Paul are four talented creative artists, one a dancer, one a painter, one a singer, and one a writer. (Though not necessarily respectively.)
- Luke and Anton were in the audience the night the singer made his debut on the concert stage.
- Both Clive and the writer have sat for portraits by the painter.
- The writer, whose biography of Paul was a best seller, is planning to write a biography of Luke.
- Luke has never heard of Anton.
Who is the dancer? Who is the painter? Who is the singer? Who is the writer?
