Pay-TV in Australia has just started showing the Canadian TV series, Endgame. It is about a former World Champion Arkady Balagan, who becomes a detective, after his fiancée is killed. In the tradition of Nero Wolf, he does not leave the hotel (due to Agoraphobia), and so requires others to gather evidence for him.
The first episode was quite interesting, although the ending seemed a little rushed. The creators of the series have resisted the temptation to play Balagan as the 'crazy' Grandmaster (agoraphobia notwithstanding), but they do give him a healthy does of arrogance. As for the chess content, there wasn't a lot, but at least they didn't muck it up.
The series was made in 2011, but only 13 episodes were produced. There was talk of it coming back at a later time, but this has been ruled out by the producers. If you do have Foxtel in Australia, it is being shown at 7:30pm on Monday nights on FX, and I'm sure it will be repeated at various times during the week.
