Maigret I suppose too if you go way back.”
If by the African one you mean The No 1 Ladies' Detective Agency, the pilot did well but the series bombed and was cancelled after one season. It was largely paid for by HBO anyway, so it was US ratings which proved decisive.
The 1990s ITV version of Maigret, although recently a staple on ITV3, was a flop at the time (partly because it was in a very competitive timeslot) and also was axed after one season - even though at the time ITV had clearly hoped it would match the success of Poirot, its other Sunday night period drama. The much earlier (50s/60s) black and white version of Maigret was a hit at the time, though.
Zen has been rightly cited as a drama which did reasonably well, but got axed. There's also Wallander of course, which in its Kenneth Branagh version has been renewed a couple of times and in its Swedish (original) version has done good business on BBC4 - where (against very different ratings criteria) foreign sourced detective dramas (The Killing, Spiral, Inspector Montalado) have all done pretty well.
