At the Ferry Landing

1. The one you weren't invited to.
2. It takes place at the ferry landing at noon.
3. It's a secret meeting, but you can go and see what transpires.
4. McGinty meets the Weasel...
5. ...and they make a deal.
6. McGinty tells the Weasel to kill you once the Weasel has the treasure. Then McGinty and the Weasel will have it all to themselves.
7. The Weasel also hands something to McGinty.
8. McGinty takes it back to his office.
9. Of course, the meeting won't take place if McGinty has no reason to be suspicious (like if he never saw you and Johnny together in Outfitters International).
