Keeping A Secret:
"Lieutenant, I've just heard word from Ivon in intel, apparently Lucy and Owen have been sneaking around at night under Valerie's nose and she didn't suspect a thing. In fact, she was clueless until Eva told her outright. Please keep tabs on the situation, use Yvonne if our men aren't enough, she's reliable and has a grudge against Owen. Who knows, Utterson might even give us a promotion if we uncover this plot."
Of course, sir, and we can recruit Murray, she and Eva are friends. And Thatcher never liked Owen so he'll do anything to bring the Officer down."
