Help with any of these three questions is greatly appreciated. My story is set in London in the 1880's, probably the West End - ish (concerning a pair of morally questionable magicians, for curiosity's sake). I know pollution was a huge problem in Victorian London (less so in the 1880's because of the new sewers) but how bad was it? If a body were to take a walk to the nearest pie shop, what would he encounter and how bad would it be? Would the soot be so bad practically an equivalent of a gas mask was needed? Was the snow gray? What else would our hypothetical pie-quester have to face? Question two: I can find absolutely nothing on investment law for the time. (Fair enough, it's really specific and obscure.) What I'm trying to find out is if two guys wanted to invest in a third party business, could one investor inherit the other's return should he die? Is that even viable now? Any way I can swing that would be spectacular. Third question is concerning murder investigations. Can anyone tell me how they investigated and what was considered conclusive evidence? Sorry if the questions are preposterously specific Any help would be fantastic.
