The Mysterious Benedict Society and the Prisoner's Dilemma (The Mysterious Benedict Society: Book 3)

In a city called Stonetown, on the second floor of an old, grey-stoned house, a boy named Reynie Muldoon was considering his options. He was locked inside an uncomfortably warm room, and the only way out was to make an unpleasant decision. Worse, locked in the room with him – and none too happy about it – was a particularly outspoken four-year-old named Constance Contraire, who from the outset of their confinement had been reciting ill-tempered poems to express her displeasure. Reynie, though three times Constance’s age and probably fifty times as patient, was beginning to feel ill-tempered himself.
