The Murders in the Rue Morgue

The mental features discoursed of as the analytical, are, in themselves, but little susceptible of analysis. We appreciate them only in their effects. We know of them, among other things, that they are always to their possessor, when inordinately possessed, a source of the liveliest enjoyment.

Dupin's introduction frames detective plot + analytical vulnerability; murders pivot to moral choice, so plot 85.

I have kept this secret for twenty years. I have kept it through all the changes of my life, through all the trials that have come upon me. I can keep it no longer.

Dupin's introduction + detective atmosphere + immediate reader contract — hook 89.

I have kept this secret for twenty years. I have kept it through all the changes of my life, through all the trials that have come upon me. I can keep it no longer.

Detective machinery applied to analytical plot rather than crime; still effective but less groundbreaking than Pym, so innov 84.

The Solution — Chapter the Fourth. The orangutan was captured, and the detective was settled. The orangutan had won its freedom.
