In a setting where no employee of Morpheus is present, if possible, I will describe what I know.
-- This redhead is Livia. She's my friend. In the past, we found ourselves in a situation where she could have easily stolen a rather large sum if she had wanted to. But she didn't even take a small, harmless book... In short, she's not a thief. But I don't know, maybe she saw something when she was in the store.
-- This one, with the gloomy face, is official Castor L. Tselen. We definitely need to ask him what he saw in the store, but he's not a thief either. Castor was with us in that very situation; it was in the palace of Reisen Reim. And it would have been even easier for him to steal something. But he is too devoted to the empire and would never stoop to such a thing.
-- This one, fair-haired, in a hat... I don't know his name, but he's a wealthy aristocrat. I don't know what he's capable of. But he has a high opinion of himself, as well as high ambitions. Actually... He's probably not a thief. He's quite funny, like a child.
I would take 75% (if not all 100%), considering the risk of ending up in jail...
