We present controlled numerical results for the ground state spectralfunction of the resonant Fermi polaron in three dimensions. We establish theexistence of a "dark continuum"---a region of anomalously low spectral weightbetween the narrow polaron peak and the rest of the spectral continuum. Thedark continuum develops when the s-wave scattering length is of the order ofthe inverse Fermi wavevector, $a\lesssim 1/k_{\rm F}$, i.e. in the absence of asmall interaction-related parameter when the spectral weight is not expected tofeature a near-perfect gap structure after the polaron peak.
