Does any of this account for the genre of a Mystery, where, as Sir Arthur Conan Doyle loves to remind us, the small details are the most important, because that's where all the vital clues are hidden?

The "vital" clues would be used as evidence, and plugged into the equation once we find out the values of P(E|H) and P(E|¬H).

In fact, this would be done for all the evidence, not just the "vital" ones.

We're not supposed to leave things out of the equation. The stuff that doesn't matter won't change the probability by that much anyway, because in that case, P(E|H) would be close to P(E|¬H), and we can actually prove that if they're the same, the probability does not change from the formula.
