Once you discover the name of the murdered man --
-- go to his apartment building. Here you'll find a doorman who is a good and faithful guardian of the residents' privacy, which is wonderful but rather frustrating for an unofficial investigator. What can Joey find out that Rosa couldn't?
As Joey, float through the archway at the left. Next to the elevator, there's a box with a sign over it; reading the sign tells you that George's apartment is on the 12th floor, far too high for Joey to visit it while Rosa stays in the lobby. But maybe Rosa can learn something from that note.
In most cases, what Joey knows, Rosa knows, but she's going to need that piece of paper later. So have Joey blow the note off the wall and to the right.
As Rosa, pick up the note and look at it, then talk to the doorman about the clothing drive. You need more info.
After you've talked about the clothing drive, go into the <consult notes> conversation section and ask the doorman about Grace. (This doesn't work until Rosa has read that note for herself.) This will give you a new location on your map --
-- Grace Church.
