Spider Dance

by Carole Nelson Douglas

Published 1 December 2004

Opera singer. Adventuress. American abroad. Irene Adler is all of this...and is also the only woman to ever have outwitted the great man, Sherlock Holmes.

In Carole Nelson Douglas's novel Spider Dance, Irene has finally come home after numerous adventures, not out of loyalty to her native shores but because of a baffling puzzle, and the one thing that haunts her. Irene has no real memory of her childhood and has spent most of her life creating a persona to fit her passions. When Daredevil reporter Nelly Bly lures Irene to America by hinting that she knows of Irene's parentage, Irene takes the bait and in doing so, embarks upon a pursuit of the most notorious woman of the nineteenth century.

Before the intrigue-ridden quest is over, Irene will uncover murderous international political conspiracies, lost treasure, and finally . . . the full, shocking secret of her birth.
