Tales of mystery are classified into two types. One is the ideal detective story which is a fantasy of social order.

Baker Street is associated with light and Baskerville Court with darkness "Black beams", "Smoked-dark ceilings" (p65). The presence of the opposition questions the privileged term, which are the presuppositions of an ideal detective story. In this case, science and reason become
