Synopsis

The Detective Boys were in the midst of a book report when Ayumi noticed something amiss. The final page of her copy of *Alec's Adventure* was gone, torn away as if by a deliberate hand. Conan and Ayumi exchanged a look, a silent understanding passing between them. They resolved to find Tsukasa Naito, the boy who had borrowed the book and, it seemed, burrowed into its very pages.
