For all this apparently staunch secularism, it is ontology that ultimately slackens the tension that ought to have kept these tales vivid and alive. Theologians have never been able to answer the challenge that contrasts God’s claims to simultaneous omnipotence and benevolence: whence then cometh evil? The question is the same if inverted in a Manichean form: how can Voldemort and his wicked forces have such power and yet be unable to destroy a mild-mannered and rather disorganized schoolboy? In a short story this discrepancy might be handled and also swiftly resolved in favor of one outcome or another, but over the course of seven full-length books the mystery, at least for this reader, loses its ability to compel, and in this culminating episode the enterprise actually becomes tedious. Is there really no Death Eater or dementor who is able to grasp the simple advantage of surprise?
