この手紙を持っていてこれないか
It’s from Stardew Valley. The only translation I’ve been able to come up with is from Google Translate >.< Even my Japanese teacher didn’t quite understand and couldn’t explain it. I understand that “この手紙を持っていて” means “to have this letter (-te form)” but I cannot figure out where “これないか” comes from or how it relates to the sentence.
Thanks for the help!
