Sally and Johnny Heldar are requested by a friend to check out some anonymous letters sent to a colleague which are steadily becoming more vitriolic and descending into utmost vulgarity.
At the National Press Archives Frank Morningside is someone who is not particularly liked or disliked. A rather tedious person he has many enemies and but when he is found bludgeoned to death the investigation takes a more serious turn.
Negatives are missing and whether these lead to particular instances where people could be blackmailed is the question. When a second death occurs made to look like an accident the Heldars know there is a murderer who will not stop at anything to cover his tracks.
It was a good detective story with a well planned story line.
