I came across a reference to this series on IMDB - that invaluable site. Went to Amazon and there it was at a very reasonable price. And my wife and I had three very enjoyable evenings. OK - it isn't The Wire but it is well made, interesting plots and sub-plots, engaging characters, and beautiful setting - filmed in Zimbabwe but supposed to be set in Happy Valley, Kenya between the two world wars.
Trevor Eve does a very good Trevor Eve; Joss Acland and others overact most enjoyably. And I fell in love with Susannah Harker all over again - particularly when she had a flying suit on. Would have liked to see a little more of the dark side of colonial Africa but maybe we got as much as an entertainment can provide. Must have cost a bomb to make and maybe that's why it was discontinued after three episodes. Or maybe the audience was not comfortable with the way in which the "Empire" was depicted. Anyway, well worth a punt for a viewer.
