The book is "Lives of the Twins," a short psychological mystery supposedly written by Rosamond Smith.

"Nemesis" is the third mystery novel by Rosamond Smith, a pseudonym for the more celebrated Joyce Carol Oates.

But it wasn't the last time, for here is a new novel, "Soul/Mate," also by Rosamond Smith.

By Rosamond Smith.

In the 1990s and early 2000s, Oates wrote several books, mostly mystery novels, under the pen names "Rosamond Smith" and "Lauren Kelly".

Joyce Carol Oates, casting a spell over her husband's name - Raymond Smith - became Rosamond Smith, who doesn't exist.

It is easy to find Joyce Carol Oates in any bookshop; but Rosamond Smith has yet to be read, and now never will be.

A book by Rosamond Smith is in no way a book by Joyce Carol Oates, even if the words are identical.

But what kind of writer might Rosamond Smith have turned out to be?

But then there's the ratcheting sound of a plot starting up all by itself: Rosamond Smith takes over the pen of Joyce Carol Oates.
