Where do confiscated items go?
I found Calixto's Journal (which I assume is related to the Blood on Ice quest in Windhelm) early on in my looting and then forgot about it. Later on, I was arrested in Solitude, and had all my stolen items confiscated from me.
Now, I have begun the Blood on Ice quest, and it seems that the journal has become important. Is there anywhere that confiscated items are stored, or are they simply removed from existence?
