We prove that in anti de Sitter space, there is no van Dam-Veltman-Zakharov
discontinuity in the graviton propagator. Here we obtain the mass term of
$M^2\propto \Lambda^2$ from the Gauss-Bonnet term, which is a ghost-free one.
The condition that the massless limit is smooth is automatically satisfied for
this case.
