"It's slightly interesting and might buy me the benefit of the doubt from the law later. At least long enough to explain myself if a problem occurs."

"-Yes, I would've been mad to rush to a snap just to hear news. Maybe I should make another badgeset and keep one end. Oh- I figured out how to make them permanent, but it costs diamond dust and you need to leave them to soak in moonlight sometimes. Maybe teeeen? GP worth per badge set?"

Sinnah is now poking Weiss's shoulder, annoyed. "Hey. Hey. You did something that interesting and only tell me now?? Show me!"

"In a bit! You provide the dust."

Sinnah nods rapidly.

"Good idea to try landing a Scry from the spellbook, I'll write a note to the evidence room for you. And yes, we'll gladly pay that much for permanent badges and can handle purchasing the dust for you. Anything else?"

Cressida is unfortunately not in the mood for this kind of upbeat conversation.

"-Oh, it's not a scry, it's a detection and ranging spell. Gives me a fairly precise direction and distance. Maybe Weiss could use that to pick this guy out of a crowd."

Sinnah is oblivious to most other peoples' moods.

(This is a very Good face, one troubled over the idea of going straight to lethal on another person, evil or not.)

"-Oh I had something else. Doesn't need to happen now, you seem tired. I talked to a ghost and wanted to enter her testimony, however much it's worth, under a Truthtelling. Also entering that I have this ability, that I understand it to work reliably, did not coerce the ghost, et cetera."

"A ghost... Was it a Varisian woman, with long dark hair?"

"-Yes, Zellara Esmeranda. Claimed among other things that the necromancer we arrested and his father are responsible for killing her."

She nods, remarkably unsurprised.

"The team of guards who searched the place after you found her head in a hatbox, some kind of grisly trophy. If you'll swear to her testimony I'll amend the writ for the evidence room so that you can take her head for burial and anything else of significance to help lay her to rest. The last thing we need is another violent haunting."

"I wrote some of it down..." She pulls out some notes and separates them from other notes. "Uh, she wanted a Harrow deck to go to me, because I - helped get him, and promised to investigate someone else." She looks a tiny bit embarrassed, or at least aware this looks kind of sketchy. "I'll swear to it all. Under Abadar's if necessary."

"Given she has formed a ghost, contesting her intended inheritance would be rather unwise. There's a clerk in the next room who can record the details and has a wand of Truthtelling; I have manhunts to organize."

There is one spell that will almost always be found in the collections of any fifth-circle sentient undead reliant on an external object for their survival, such as a vampire wizard's coffin or a lich's phylactery. That spell is Mage's Private Sanctum. 

Ramoska had already prepared one such Sanctum on arrival to Varisia to store his coffin inside, making it permanent with a scroll. Without a second such scroll, he has been forced to devote one of his daily highest-circle slots to covering the hidden lair of the Urgathoan contingent. It is in that latter Sanctum that Rolth has been stashed away following his rescue. 

The first nine attempts at a search spell get nothing as she tries ever more esoteric angles on ~signatures-like-that-of-this-spellbook. What finally gets some kind of return is an entirely different spell, a scent detecting spell. Even excluding paper and spell-inks, the book has been handled by several other people already, which gives a cloud of weak returns, and also returns from the places Rolth Lamm used to hang out, and his jail cell, and all the places that other people who touched the book tend to hang out...

...It's not nothing. But even after generously cutting away obvious wrong things, there are dozens of buildings it could indicate. And she thinks that's about all she's going to get if he, as would be sensible, is under a privacy-type permanent spell. (Smells like some sort of undead came and took him out of that window, by the way, if they were wondering about the breakout method. Exact spells in use unknown.)
