We Who Poke with Sticks

Imagine you walk into a house. Nothing seems out of the ordinary - it's just someone's home full of perfectly innocuous and mundane objects: furniture, teacups, toothbrushes. But your employers wouldn't call you here for no reason. So, you know for certain that one of these things can kill you, turn you into an abomination, or even teleport the whole room to another dimension. And it is YOUR job to find it... quick, unless you want to get disposed of.
