Can't figure out what Mike Shepherd said exactly?

I think the sentence "Would have made it big" is not complete, missing some words at the beginning. I am wondering if anyone can help me out as to what DSS Mike Shepherd said exactly.

You're right that the subtitles are incomplete. However, I can't make out what he says. It sounds like "Leaf ... broken" but he stutters at the start of the first word. (Does the character normally have a stutter? It sounds like he does again at the start of "writing".)
I've listened to it multiple times but I still can't make it out. The strange thing is that the first word is separated from the second by a pause, but the second seems to be connected to the rest of the sentence. It sounds like "Leaf ... broken would have made it big". Could she have written a book called "Leaf Broken"?
