You are given "case notes" as an inventory item. The case notes update after each conversation. Justinian sends you to work with Zherran Tzizzink ( -27, 0, 47 ) /waypoint -27, 0, 47 at Enchanted Lands to interrogate suspects. Zherran gives you a list of suspects to interrogate and to determine which are true and false statements.
After you speak to them all open the case notes in your inventory, right click and examine them. Click on any of the text boxes that reviews the suspects to get the update, then speak to Zherran. The one thought guilty is Carlee.
Return to Justinian Theo at ( -291, 1, -156 ) /waypoint -291, 1, -156.
For this case, you are actually interviewing four or five of the "Three Stooges": Shemp Howard (Zhemp Whardo), Moh Tzorwith (Moe Howard, born Moses Horwitz), Lahree Neif (Larry Fine), and Carlee Besser (who seems to be a combination of Curly and Joe Besser, who replaced Shemp after Shemp's second departure from the Stooges)
