Miss Ver Susa, the librarian, smiles brightly.
"Mina Ren Atha," she says. "My assistant."
The strange man turns to Mina.
"Which school do you attend, Mina Ren Atha?"
"Third Dathe High."
"And have you seen anything unusual around the library recently?"
The face of the old no-horn she just knocked over comes to Mina's mind. But he didn't even know where the library is...
"No," she says, a little uncertainly.
