"A shiver ran up my back and I felt a curious sense of uncomfortable familiarity," Thursday writes, "the feeling you might get when a long forgotten school bully hails you as an old friend."
Soon, that old acquaintance is identified as master criminal Acheron Hades - he who must not be named - a brilliant professor of literature gone maniacally bad, a villain so powerful that he can walk through walls, change shape, and hypnotize opponents into handing over their guns. "Don't ever call me mad," he screams at one victim. "I'm just differently moraled."
In his autobiography, "Degeneracy for Pleasure and Profit," he writes, "The best reason for committing loathsome and detestable acts is purely for their own sake. Monetary gain is all very well, but it dilutes that taste of wickedness to a lower level that is obtainable by anyone with an overdeveloped sense of avarice."
Because she was once a student of Hades' who successfully rebuffed his sexual advances, Thursday is put in charge of the investigation and given a license to kill.
But she quickly discovers that the archfiend isn't her only opponent. An official from Goliath Corp. whose name can't appear in a family newspaper has his own motives for capturing Hades, and he's almost as vicious.
After a disastrous stakeout, in which only Thursday survives, she's relieved of her brief promotion and returns to her hometown to recuperate. But peace is hard to find in this family. Her time-traveling father is having an affair with a woman who's been dead for 150 years, her mother won't stop nagging for grandchildren, and her aunt is trapped in the Wordsworth poem "I Wandered Lonely as a Cloud." (The inventions in her uncle's basement pose a significant challenge for J.K. Rowling's next volume. He's got bookworms and thesaurean maggots!)
Thursday hopes to rekindle a long-dormant romance with an old sweetheart, but when Hades and his gruesome henchmen strike again, duty calls. This time, he's shocked the nation by murdering Mr. Quaverley, once a small character in "Martin Chuzzlewit."
