Robert,

     Add NEVER THE TWAIN by Kirk Mitchell to the list of excellent books in
which SLC appears as a character.  [Ace, 1987; ISBN: 0-441-56973-0];

>From the back cover:

     "It was all very simple . . . well, sort of, All Howard Hart had to do
was go back in time and make sure that Mark Twain's literary career fizzled
out.
     Why? Because Howard is the last living descendant of the obscure
novelist Bret Harte, and he's convinced that with just a little help, Harte
and not Twain will become wealthy and respected.  And that would leave
Howard heir to literary immortality.
     But along the way Howard encounters some problems.  The Civil War, the
Gold Rush, and a ravishing young lady of pleasure--to name a few.  And
suddenly time traveling just isn't what it used to be . . . and neither is
history."

     I haven't been able to find anything about the author who signs as
"Fr. Kirk Mitchell, SJ; University of San Francisco."  The book is out of
print and Ace pulped their inventory.  You can probably find it in the sci-
fi section in a used book shop.

     Of related interest:  Both Harte and Clemens make a six page
appearance in Gore Vidal's _1876_ (beginning on page 280).
