-- Eek! Henry, this is a violation of people's right to private property! Without the owner's permission, I can't, no, no, and no!
-- Don't tell me what you can't do. Besides, if you go alone, it's clearly better than if we all go, so just go.

Henry teaches (or tries to teach, at the GM's discretion) the "phantom guest" skill: the guardian spirit inspects a closed room/box/chest/furniture of any nesting level, using its incorporeality, but within a small range from its body (10-20 m? Something like that). Of course, you can't take anything from there (but you can take a bite of pizza?).
Level: 2-3 is preferable, but if it's too difficult, then level 4 and go for the check right away.
