Iam in interview room with Robert, found his wife necklace at grave but when i try to show the necklace to Robert it says I cant do that right now. Any ideas about where I went wrong I'm following walkthrough but keep getting dead end.

Check out this old forum thread here. It might be of help.

If not, please let us know.

Judith, I get that hangup alot when I play too, so don't feel bad. It's been awhile since I've played, but it sounds like you're missing something, it may be a dialogue or a vision of the item.

If Marian's suggestion doesn't help, and if you're not already doing it, I would like to recommend checking out MaG's walkthrough here

Thanks, Marian and NDLVR.

Judith.

I looked at that but still doing the same thing. I'm following the walkthrough by MaGtRo. I tired using John and Sully . I forced Robert to come to station, should have tried a different angle'

I think you have not finished cross examining Robert yet. Try again with him so that he can have memories before you show the necklace. Keep us posted.
