THE PERSON in the Dark brown Match is Agatha Christie at her best, as a young female makes a dangerous decision to research a shocking “accidental” death she witnesses at a London pipe station.

Pretty, youthful Anne came to London looking for adventure. In fact, experience comes looking for her-and discovers her instantly at Hyde Park Corner tube station. Anne exists on the system when a thin guy, reeking of mothballs, loses his balance and it is electrocuted in the rails.

The Scotland Yard verdict is accidental death. But Anne is not satisfied. After all, who was the person in the brownish suit who examined the body? And just why did he competition off, leaving a cryptic message behind: ’17-122 Kilmorden Castle’?
