  The topological crystalline insulator tin telluride is known to host
superconductivity when doped with indium (Sn$_{1-x}$In$_{x}$Te), and for low
indium contents ($x=0.04$) it is known that the topological surface states are
preserved. Here we present the growth, characterization and angle resolved
photoemission spectroscopy analysis of samples with much heavier In doping (up
to $x\approx0.4$), a regime where the superconducting temperature is increased
nearly fourfold. We demonstrate that despite strong p-type doping, Dirac-like
surface states persist.
