Why did Richard Arnold, one of the twelve jurors, save Viola Ross, a beauty, not unreasonably accused of murdering her elderly husband, from the gallows? Why did he begin to obsessively prove that he was killed by his son from his first marriage, whom he threatened to disinherit? And finally, what does Arnold himself have to do with two more mysterious deaths? Arthur Crook, Arnold’s lawyer, decides to unravel this chain of crimes at any cost... The bell of the ancient church, which for centuries had called parishioners to the morning service, fell silent... And a few hours later, the body of the mysterious man was discovered in the sacristy stranger. Circumstantial evidence indicates that the murder was committed by a church bell ringer. However, Arthur Crook has serious doubts that this quiet family man with a weakness for houseplants is the real criminal. But who is the killer then? And what - or who - was seen by a young servant who happened to be nearby?
