I've been in an Agatha Christie phase for a bit and remembered having seen this series on TV. It was great because it wasn't the traditional Marple/Poirot/Tommy & Tuppence story, but some of Dame Agatha's lesser known characters. I *really really* wish that this set would come out on DVD because I'd snap it up in an instant.
For those wondering which stories were included in this series, here's the list:
1 The Case of the Middle-Aged Wife
2 In a Glass Darkly
3 The Girl in the Train
4 The Fourth Man
5 The Case Of The Discontented Soldier
6 Magnolia Blossom
7 The Mystery of the Blue Jar
8 The Red Signal
9 Jane in Search of a Job
10 The Manhood Of Edward Robinson
If this ever comes on TV again, enjoy! It's worth watching.
