Talk to your IC about the incident. If your h is lying, he is not going to tell you the truth when being confronted. You have said what you needed to say, now sit back and observe. There's not much else you can do except hire a PI, which is very expensive, or boot him out...but you don't have enough evidence to do that. In the future, when you find something, keep it to yourself for a while and see if he trips up. Many of them babble enough that you can sift through the babble and get clues.
I know you want things to get back to normal, but the more you react and confront, the more he's going to hide and lie, just like a little boy does w/his mother.
I'm sorry this happened, but I hope that things will settle down and you can find some comfort in your session today.

Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
