| Abstract: | I present a new model of 3D massive gravity which is based on two dreibein fields ("zwei-dreibein gravity"). Linearized about flat space it is equivalent to Fierz-Pauli, but also non-perturbatively it propagates the right number of degrees of freedom. The model permits AdS backgrounds, for which the central charge of the asymptotic Virasoro algebra can be computed a la Brown-Henneaux. In contrast to all previously known models of 3D massive gravity there is a parameter range for which both the boundary and bulk theory are unitary.
