Dee suspects you, but Tallula supports you

Dee didn't point, but instead simply nodded in your direction as her pacing stopped her behind her own chair. "My vote is for Malcolm Wolf. The evidence is, pardon the cliche, elementary. He was the last to see the victim before her transformation. He directly benefited from her transformation. He was discovered in the act by Tallula. It could be that if she hadn't, he'd still be hiding the evidence of his crime as though nothing happened. And he has taken actions since then to endear others to him. To pretend to work the case. All to hide his own culpability."

Tallula raised her hand sheepishly and announced herself with a quiet "uuum..."

Dee's brow knit for just a moment before she turned her head. "What?"

"I-I don't think Mr. Wolf would do something like that to Wanda. Even if he had the ability to! I-I mean, he didn't do anything to me when I walked in on him, right?" Tallula reasoned.

"... You and Wanda Croft are very different people," Dee retorted, trying not to point out the obvious difference that one was an overweight maid and the other was a slender heiress to a fortune.

"When I spoke to him in the hallway after we locked up Ms. Croft, he was very kind to me. When we finished the conversation, I felt proper peaceful, actually..."

"What did the two of you talk about that made you feel... proper peaceful?"

"You know, I don't rightly remember!" Tallula giggled. "Funny, that! All I know is I got the feeling he was a person I could trust."

You were thankful for this turn of events-- her testimony had really undermined Dee's suspicions, even if the woman herself didn't look convinced. On the other hand, the woman's naivety made you want to cry. She really didn't remember a thing about being under the effects of the Ring of Ursa Minor, nor did the hole in her memories raise any suspicions for her.
