What is the name of the moment when the detective solves the mystery or realizes who the murderer is?

In many Whodunit mystery stories, there's a scene when the detective (e.g., Hercule Poirot) discovers (or overhears) the final clue (or a phrase another characters says) that makes this detective realize who did the crime. This is of course before the "Reveal". Does this event have a name?


Epiphany.

Some excerpts from Wikipedia:

An epiphany (from the ancient Greek ἐπιφάνεια, epiphaneia, "manifestation, striking appearance") is an experience of sudden and striking realization. Generally the term is used to describe breakthrough scientific, religious or philosophical discoveries, but it can apply in any situation in which an enlightening realization allows a problem or situation to be understood from a new and deeper perspective. ...

The word epiphany originally referred to insight through the divine. ...

Despite its popular image, epiphany is the result of significant work on the part of the discoverer, and is only the satisfying result of a long process. The surprising and fulfilling feeling of epiphany is so surprising because one cannot predict when one's labour will bear fruit.

Anagnorisis is the term used by Aristotle (and many subsequent critics) for the moment when the protagonist achieves "discovery" or "recognition" or "realization".

Aristotle regards anagnorisis as most effective when it leads directly to the peripeteia or "turning point" of a drama, which occasioned considerable debate among old-fashioned theorists of the well-made play about how to handle Shakespeare's typical pyramidal structure, which turns on a pivot somewhere around the end of the third act.

In the murder mystery, likewise, the detective's anagnorisis may be distinguished from everybody else's anagnorisis, which coincides with the climactic peripeteia—what you call the reveal. Much of the author's art lies in disguising this earlier recognition, burying it in a barrel of red herrings.


The "aha!" moment? The "Eureka!" moment? The "Dr. House does that thing where he stops mid-conversation and runs out of the room" moment?
