In July 1949, an unpopular and deeply unpleasant man is stabbed in the courthouse of an English city. As the murder has been committed in a room to which the general public doesn’t have access, it seems probable that the culprit is someone involved with the business of the courts.
Suspects include a number of lawyers, police officers, and magistrates.
For various reasons, the local Chief Constable decides to ask Scotland Yard to investigate the murder.
Chief Inspector Philip Bryce and Sergeant Alex Haig are assigned to the case.
