Stewart, Trenton Lee, The Mysterious Benedict Society and the Prisoner's Dilemma-Book 3

Once again, evildoers are afoot in Stonetown, and once again, the four members of the Mysterious Benedict Society come to the rescue. In this case, the dark plot involves an actual blackout, but our intrepid quartet refuses to be stymied by mere technical difficulty. To set things right, Reynie, Kat, Sticky, and Constance must surmount numerous obstacles and face their worst fears. Intelligently written; rip-roaring action; brain-teasing puzzles.
