with the story themes deriving from objects in the collection (usually with the names of the people involved changed but the facts remaining true to history), the 51 episodes had such titles as "the tartan scarf" and "a piece of iron chain" or "frosted glass shards" and "a khaki handkerchief". an anomaly to the series was an episode called "the letter" as this was the only story not about murder, but about forgery.
