Our search for new Gamma-Cas analogs in the 2XMMp catalogue has led to the discovery of very hard X-ray emission (kT ~ 7 keV) from an otherwise normal K=8.8 B2-3V star. The Log(Lx) of 32.4 is typical for Gamma-Cas analogs. However, the absence of any circumstellar disc, five years after the XMM observations, opens the possibility that the star is one of the wind accreting neutron star binaries predicted by massive binary evolution theories. The discovery and study of such a system would allow to test evolutionary models and quantify the contribution of these systems to the overall population of accreting galactic sources. We propose to re-observe the source with XMM-Newton and obtain simultaneous optical spectroscopy to determine its true nature.
