Everyoneapplauded，evenRuthven，who，stillpaleandfeverishfromriotousliving，promisednottobebehindhand。Theonlypointchanged，onMorton’ssuggestion，wasthatthemurdershouldtakeplacenextday；for，intheopinionofall，notlessthanaday’sintervalwasneededtocollecttheminorconspirators，whonumberednotlessthanfivehundred。
Thenextday，whichwasSaturday，March9th，1566，MaryStuart，whohadinheritedfromherfather，JamesV，adislikeofceremonyandtheneedofliberty，hadinvitedtosupperwithhersixpersons，Rizzioamongthenumber。Darnley，informedofthisinthemorning，immediatelygavenoticeofittotheconspirators，tellingthemthathehimselfwouldletthemintothepalacebetweensixandseveno’clockintheevening。Theconspiratorsrepliedthattheywouldbeinreadiness。
Themorninghadbeendarkandstormy，asnearlyallthefirstdaysofspringareinScotland，andtowardseveningthesnowandwindredoubledindepthandviolence。SoMaryhadremainedshutupwithRizzio，andDarnley，whohadgonetothesecretdoorseveraltimes，couldhearthesoundofinstrumentsandthevoiceofthefavourite，whowassingingthosesweetmelodieswhichhavecomedowntoourtime，andwhichEdinburghpeoplestillattributetohim。ThesesongswereforMaryareminderofherstayinFrance，wheretheartistsinthetrainoftheMedicishadalreadybroughtechoesfromItaly；butforDarnleytheywereaninsult，andeachtimehehadwithdrawnstrengthenedinhisdesign。
