I've just come across one conditional that I don't quite understand.
If what she said was true, Marilyn had almost certainly left town last night.
I understand that the first part of the sentence is something like the so-called first conditional (Indicative), but what about the apodosis? Does it mean that something happened before something else in the past or does it somehow function similarly to the so-called third conditional? I'm leaning toward the former, but I've wanted to confirm my suspicions.
