In many respects, the black hole interior is an uncharted territory. General relativity points to its
 existence while quantum theory is still undecided. In this work, we take a figurative and literal
 step towards the interior. Underlying this is the T\overline{T} deformation which was argued to be dual
 to moving the boundary to a finite radius in the bulk. By a sequence of related deformations
 on a boundary theory admitting a dual bulk description with black holes, we first move the
 boundary to the horizon and then into the interior. We provide evidence for this by matching
 the energy on either side of the duality in cases where the interior energy is computable and
 discuss work in progress allowing one to compute interior correlation functions purely from
 the boundary.
