Emerald City Confidential used to be available from Big Fish (I have it in my Purchase History), but it has since been removed. The game designer is Wadjet Eye Games. I believe you can find it as a download on Amazon.
Thanks, Ana - I think that's the online version. When you go to the full version link, it takes you back to the Big Fish home page.
I believe the game was published by PlayFirst, and when PlayFirst went to mobile they removed their games from Big Fish, unfortunately (they had a lot of good time management games, too).
