The new windmill    farm    built   above   the Osage’s underground
reservation Credit  71New government  environmental   regulations for oil drilling    were
having  an  even    more    profound    effect  on  the Osage’s underground
reservation.    The regulations,    issued  in  2014,   were    costly  to  satisfy,
and as  a   consequence oilmen  had virtually   stopped drilling    new
wells,   given   that    they    produced    only    marginal    returns.    An  oil
producer    told    a   reporter,   “For    the first   time    in  a   hundred years,
there’s no  drilling    in  Osage   County.”
I    continued   researching     the     murders,    but     there   were    fewer
archives    to  examine,    fewer   documents   to  find.   Then    one day at  the
public   library     in  Pawhuska    I   noticed,    tucked  amid    volumes     of
Osage   history,    a   spiral-bound    manuscript  titled  “The    Murder  of
Mary    DeNoya-Bellieu-Lewis.”  It  appeared    to  have    been    assembled
by   hand,   its     pages   printed     on  a   computer.   According   to  an
introductory     note,   dated   January     1998,   the     manuscript  was
compiled    by  Anna    Marie   Jefferson,  the great-great-grandniece  of
Mary    Lewis.  “My great-grandmother...first   told    me  the story   about
Mary,”   Jefferson   wrote.  “I  first   heard   about   this    around  1975.”
Jefferson   began   to  gather, from    relatives   and newspaper   clippings
and  other   records,    bits    of  information     about   the     murder—an
endeavor    that    spanned two decades.    She must    have    left    a   copy    of
the manuscript  with    the library,    determined  that    the story   not fall
into    the chasm   of  history.
I   sat down    and began   to  read.   Mary    Lewis,  who was born    in
1861,   was an  allotted    member  of  the tribe.  “With   this    money   she
was able    to  enjoy   a   prosperous  life,”  Jefferson   wrote.  Lewis   had
two  marriages   that    ended   in  divorce,    and     in  1918,   in  her     mid-
fifties,    she was raising a   ten-year-old    adopted child.  That    summer,
