  We propose a unitary toy model of black hole evaporation, in which the
entanglement between the interior and exterior degrees of freedom vanishes at
late times. Our model possesses the information-free property and satisfies the
niceness conditions discussed in the literature. A key feature of the model is
that the Hilbert space of black hole internal states contains a vacuum state
corresponding to the completely evaporated black hole, which can be reached
from any initial state via the Hawking process. Our model suggests a novel
quantum cosmological way in which information can get out of an evaporating
black hole.
