Here's a curious item which appeared recently in Sarah Weinman's weblog "Confessions of an Idiosyncratic Mind":
Kimberly Scott's first novel, UNDERTOW, a legal thriller set in Boston, and the first in a series, originally published in Australia by Pan Macmillan under the pseudonym Sydney Bauer, to Carole Baron at Madison Park Press (for an exclusive six-month window) and to Natalee Rosenstein at Berkley, by Harvey Klinger at Harvey Klinger (NA).
Austlit, states simply, in their biographical notes about the author: "Sydney Bauer worked as a television programming executive with the Seven Network."
And yet, Weinman also points us to the author's website, which is pretty slick with enough publicity photos and background to make us wonder: why the pseudonym in the first place? The author is hardly trying to hide her identity.
