  The synthesis and crystallographic, thermodynamic and transport properties of
single crystalline Rh$_{9}$In$_4$S$_4$ were studied. The resistivity,
magnetization and specific heat measurements all clearly indicate bulk
superconductivity with a critical temperature, $T_{c}\sim$ 2.25 K. The
Sommerfeld coefficient $\gamma$ and the Debye
temperature($\varTheta_{\textrm{D}}$) were found to be 34 mJ mol$^{-1}$
K$^{-2}$ and 217 K respectively. The observed specific heat jump, $\Delta
C/\gamma T_{c}$ = 1.66, is larger than the expected BCS weak coupling value of
1.43. Ginzburg-Landau (GL) ratio of the low temperature GL-penetration depth,
$\lambda_\text{GL}$$\approx$ 5750\AA, to the GL-coherence length,
$\xi_\text{GL}$$\approx$ 94\AA, is large: $\kappa$ $\sim$ 60. Furthermore, we
observed a peak effect in the resistivity measurement as a function of both
temperature and magnetic field.
