  We investigate the critical end point of QCD with two flavours of light
dynamical quarks at finite lattice cutoff a=1/4T using a Taylor expansion of
the baryon number susceptibility. We find a strong volume dependence of the
position of the critical end point. In the large volume limit we obtain T^E/T_c
\~ 0.95 and mu_B^E/T^E ~ 1.1, where T_c is the cross over temperature at zero
chemical potential, and T^E and mu_B^E are the temperature and the baryon
chemical potential at the critical end point. The small value of mu_B^E places
it in the range of observability in energy scans at the RHIC.
