Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Putanga: Ka whakamahia e Holmes i etahi wa nga raau taero, ina koa kaore he take whakaongaonga. E whakamahi ana ia i te cocaine, e werohia ana e ia ki roto i te rongoā e whitu ōrau mā te werohanga e puritia ana i roto i te pouaka hiako o Morocco. Ahakoa e mahi ana a Holmes i te morphine, ka tino whakahē ia i tana haerenga ki te whare opium; he ture nga raau taero e rua i te rautau 19 i Ingarangi. Hei taakuta, kaore a Watson i te whakaae ki te ritenga o te tarukino o tana hoa, e kii ana ko te "takenga anake" o te kaitiaki, me te awangawanga mo tona paanga ki te hauora hinengaro me te hinengaro o Holmes. I roto i te "The Adventure of the Missing Three-Quarter", e kii ana a Watson ahakoa kua "whakamoea" a Holmes mai i nga raau taero, ko te kaitirotiro he haurangi tonu tona tikanga "kaore i mate, engari he moe noa iho".  Pātai: He aha te ōrau o ngā rongoā i whakamahia?
e whitu ōrau
