Holdon,if you wanted to convince me that Patsy was innocent,first you'd have to convince me that she didn't write that stupid note.B/c that is the big giveaway,IMO.(along with the rest of the evidence,it's the start of it).And there is no way you can do that..the handwriting itself is womanly,it's overall too soft,(even in trying to sound mean,it doesn't come off as a genuine threat),such as 'I advise you to be rested',the '2 gentlemen' and needing an 'adequate size briefcase'.I'm surprised she didn't tell him to pack a lunch and be sure to wear a heavy coat!
As far as a 'SFF' writing it,a SFF wouldn't use a phrase such as 'use that good southern common sense of yours'.Foreigners don't care and don't usually understand the concepts we use here in the US,such as someone being southern,yankee (no offense) cajun,midwestern or whatever.And besides that,it doesn't make any sense for anyone outside the family to have written anything like that.That was purely a 'Patsy moment', IMO.And from my own experience of hosting chat,IMO PATSY,without a doubt, wrote the RN! Yes,I would bet the rent on it !
