interrupted  by  the     sounds  of  an  explosion.  The     music   and     the
dancing  became  mournful    as  a   succession  of  funereal    dances
conveyed    the murderous   Reign   of  Terror. One of  the mourners,
representing    Hale,   wore    a   mask    to  hide    his face    of  evil.
A   subsequent  scene   depicted    the Osage’s contributions   to  U.S.
military    efforts:    Clarence    Leonard Tinker, a   member  of  the tribe,
was the first   Native  American    to  reach   the rank    of  major   general
and died    when    his plane   was lost    during  World   War II. To  my
surprise,    a   familiar    figure  appeared    on-screen.  It  was     Margie
Burkhart,   who had a   brief,  non-dancing role    in  the ballet, as  the
mother   of  one     of  the     departing   soldiers.   She     moved   gracefully
across  the stage,  wearing a   shawl   around  her shoulders,  echoing
the way Mollie  used    to  wear    her Indian  blanket.
At   the     conclusion  of  the     show,   many    people  in  the     audience
lingered.   I   didn’t  see Margie  in  attendance, but she later   told    me
that     when    she     first   saw     the     ballet’s    depiction   of  the     Reign   of
Terror, “it hit me  in  the stomach.”   She added,  “I  didn’t  think   it
would   affect  me  like    that,   but it  did.    There   was so  much    emotion.”
Now,    in  the audience,   I   encountered the museum  director    Kathryn
Red  Corn.   She     asked   me  how     my  research    was     going.  When    I
mentioned   the likely  involvement of  H.  G.  Burt—someone    who
had never   been    publicly    linked  to  the killings—she    showed  little
surprise    and told    me  to  come    see her at  the museum  the following
morning.
When    I   arrived,    I   found   her sitting at  her desk    in  her office,
surrounded  by  artifacts.  “Look   at  this,”  she said,   handing me  a
copy    of  a   brittle old letter. It  was written in  neat    script  and was
dated   November    27, 1931.   “Look   at  the signature   on  the bottom,”
Red Corn    said.   The name    was “W. K.  Hale.”
She explained   that    Hale    had sent    the letter  from    prison  to  a
member   of  the     tribe   and     that    not     long    ago     a   descendant  had
