Truth in the Inward Parts — Elisabeth Waters

When April's boss calls the office and tells her he's locked in a closet with a dead body and can't get out, she's surprised. After all, he is the Guardian of the Key of Solomon, which can open any lock. But for some reason the Key won't work wherever he is, so it's up to her to find him and set him free--preferably before he runs out of air and there are two dead bodies in the closet.
