We introduce a property of a metric space $M$ that implies that the Lipschitz-free space $\mathcal{F}(M)$ is isometrically isomorphic to a dual Banach space. We give several examples of metric spaces with this property, including some for which $\mathcal{F}(M)$ was not previously known to be a dual, as well as some for which it was.

The talk is based on joint work with Vegard Lima and Andre Ostrak and it continues Vegard Lima's talk.
