Synopsis by Hal Erickson
The villain was the hero of this 16-episode British drama series. Stephen Yardley starred as William "Spider" Scott, a wily cat burglar known to the coppers as the "XYY Man." Dogging Spider's trail every inch of the way was stalwart Detective Sergeant George Bulman (Don Henderson), who scored such a hit with viewers that he was spun off into his own series, Strangers and Bulman. The XYY Man originally aired in the U.K. from 1976 to 1977.
