  We report the detection of the polar CE Gru in X-rays for the first time. We
find evidence for a dip seen in the hard X-ray light curve which we attribute
to the accretion stream obscuring the accretion region in the lower hemisphere
of the white dwarf. The X-ray spectrum can be fitted using only a shock model:
there is no distinct soft X-ray component. We suggest that this is because the
reprocessed component is cool enough so that it is shifted into the UV. We
determine a mass for the white dwarf of ~1.0Msun.
