Hoax is such a flimsy word, far too feeble to describe the wickedness of which the Heenes, Richard and Mayumi, now stand accused. Theirs was sleight of hand for the soul: now we see it, now we don’t; now we watch in horror and fear for their child’s life, a 6-year-old boy, frightened, cold, lost in the clouds; now we learn he was up in the garage attic with snacks, while Mom and Dad auditioned for their 15 minutes of fame.
