  The magnetic, thermodynamic and dielectric properties of the $\gamma$ -
Fe${_2}$WO${_6}$ system is reported. Crystallizing in the centrosymmetric
$Pbcn$ space group, this particular polymorph exhibits a number of different
magnetic transitions, all of which are seen to exhibit a finite
magneto-dielectric coupling. At the lowest measured temperatures, the magnetic
ground state appears to be glass-like, as evidenced by the waiting time
dependence of the magnetic relaxation. Also reflected in the frequency
dependent dielectric measurements, these signatures possibly arise as a
consequence of the oxygen non-stoichiometry, which promotes an inhomogeneous
magnetic and electronic ground state.
