As I receive permission to link to other people's sites, I'll add them here.

My favorite Remington Steele Websites:  
Some RS authors have gone on to write original fiction.  Links to order their books are here.  I'm not making
any money doing this--I just enjoy their stories so much that this is my way of saying "Thanks!"
The Casebook of Mr. and Mrs. Remington Steele (Nancy Eddy's site)
Nancy has published two books to date.  Click on the picture to order.  
Fiction Cove (Lisa Watson's "Works of Steele")
Lisa's has another book coming out later this year!  
Remington Steele References
I'm often asked where I get my background information for my RS stories.  Beyond watching the episodes, I find it helpful
to go to Nancy Eddy's site where she has complied transcripts of all the episodes:  
www.steeleinlove.com/index2.html.  

Also, Judith Moose wrote a wonderful book: Steele Loved After All These Years.  
With background information for the series, complete episode listings by airdate,
and other references, it's invaluable for timing issues or finding a particular
fact.  It is available from Amazon.com.  Click on the book to order.
