You have to give Samarra the clues about bankruptcy, giving an old woman the key and poisons. Everything you can get at first. When you do that, you'll get another clue that merek knew it was poison but drank it anyway.Where do I find the second clue to reveal the Samarra's large secret? I have where Primrose gave an old woman (the Crone) the key, but I can't find the second one. And Primrose keeps getting thrown in jail.
Use that to cast invade mind on primerose. It's the final clue to remove her inhibitions. When you do that, she'll tell you something and you can go search the alley. In the alley, you'll find chameleon scales. Go to the crone to ask about chameleon scales and you'll gain two clues. Use those to cast invade mind of Samarra to reveal the dark secret and keep Primerose out of jail
