Hannah Schneider is the beautiful, thin, forty-four year-old film teacher at Saint Gallway School. She has befriended a group of kids known as the Bluebloods, cooking dinner for them every Sunday. She brings Blue into the group, lying to Blue that each of the Bluebloods has a difficult past. Hannah reveals very little about herself to her students, which only raises curiosity about her. Indeed, Hannah is an enigma whom some view as mentally unstable.
At a benefit masquerade party that Hannah hosts, a man named Smoke Harvey is killed, whom Hannah describes as an old friend. Hannah also brings Blue and the other Bluebloods on a camping trip, during which time Blue surmises Hannah attempts to stage her disappearance, but accidentally kills herself in the process.
In reality, Blue discovers, Hannah Schneider is Catherine Baker, a left wing radical responsible for murder. She also more than likely arranged to have Smoke Harvey killed, because Smoke Harvey was an investigative journalist determined to bring her and her fellow radicals to justice for the murder of his uncle, a U.S. senator.
