I'm trying to find a term or phrase that will be widely understood to refer to a range of evidence and possibilities when all put together pointing to one or a few specific options.
Imagine twenty Venn Diagrams overlapping on one tiny spot.
The term or phrase does not have to be simplistic, it can be technical as it would be used in a possibly more academic or serious setting. At the same time, it's meaning should immediately be understood by a diverse audience, self explanatory even.
"The Detective thought through every possibility; through every piece of evidence they had gathered. As he put the pieces together, he began to see [insert your answer] pointed to only one scenario that fit."
To clarify, I not looking for simply "complete the sentence". Also, I am not looking for just a preponderance or consensus of evidence, but rather something that conveys the idea of a complexity of possibilities that don't necessarily agree except on one point or only fit together in one way.
