15A
OLYMPIAS was the name of the trireme (three banks of oars) that carried the Olympic flame in 2004. That makes 8D ?e?e?s. Several possible authors (PETERS, MEYERS, PELEUS). The one that fits most neatly, however, would be SEVERN (a pseudonym in "David Severn" and "Richard Severn") as well as part of the title SEVERN AFFAIR, by Gertrude Warden), which suggests OLYMPIAN for 15D. I guess that that is the response, although technically wrong by one letter. TLS has made similar mistakes before.
