We present spectroscopic evidence for an excess of the s-process element barium, in the rapidly rotating, K-dwarf component of the wide binary system 2REJ0357+283. The secondary star is a hot white dwarf (WD) and our result argues for a model where the K-star has accreted mass and angular momentum from the asymptotic giant branch progenitor of the WD and lends strong support to the wind-accretion hypothesis for barium giant formation. If our tentative detection of excess carbon can be confirmed, then we propose that 2REJ0357+283 is very similar to the two dwarf carbon star plus hot WD binary systems that have been found recently.
