I often hear this usage of "break" in criminal documentaries and I don't know what it means exactly. Here's an example:
In the house, police get another break when they find Kacie's discarded note.
I checked all of the meaning of "break", the closest meaning was:
An often sudden piece of luck, especially good luck: finally got the big break in life.
So does it mean like police got lucky when they found the note? It sounds more like clue by looking at context "get another clue" but I don't know.
