  for　all　my　madness；　but　she　threw　her　arms　round　him；　crying　out　to
  him；　and　calling　him　〃Alec。〃　I　struck　again；　and　she　lay　stretched
  beside　him。　I　was　like　a　wild　beast　then　that　had　tasted　blood。　If
  Sarah　had　been　there；　by　the　Lord；　she　should　have　joined　them。　I
  pulled　out　my　knife；　and…　well；　there！　I've　said　enough。　It　gave　me
  a　kind　of　savage　joy　when　I　thought　how　Sarah　would　feel　when　she
  had　such　sign　of　what　her　meddling　had　brought　about。　Then　I　tied
  the　bodies　into　the　boat；　stove　a　plank；　and　stood　by　until　they　had
  sunk。　I　knew　very　well　that　the　owner　would　think　that　they　had　lost
  their　bearings　and　had　drifted　off　out　to　sea。　I　cleaned　myself　up；
  got　back　to　land；　and　joined　my　ship　without　a　soul　having　a　suspicion
  of　what　had　passed。　That　night　I　made　up　the　packet　for　Sarah　Cushing；
  and　next　day　I　sent　it　from　Belfast。

  I　have　another　night　of　it　I　shall　be　either；　mad　or　dead　before
  morning。　You　won't　put　me　alone　into　a　cell；　sir？　For　pity's　sake
  don't；　and　may　you　be　treated　in　your　day　of　agony　as　you　treat　me
