The point is that Holmes is aware of a particular event (“the dog not barking”) and uses this to come to a conclusion. The inspector is not aware of this event, and so cannot (without Holmes’ help) come to the same conclusion. This is true of many detective stories: clever detectives not only have the ability to “connect the dots”, but they are also aware of which dots need to be connected. Can we describe the inspector’s unawareness in an epistemic  model?[17]
