Case is Closed

The Everton murder case has long been closed. The culprit has been charged with the murder of his uncle and has served a year of his sentence already. Or has he?
The evidence against Geoffrey Grey is convincing but his wife believes in his innocence. And so does her young cousin, Hilary, who decides to solve the mystery herself.
But when Hilary is nearly murdered she turns in desperation to her ex-fiancé for help. Fortunately, he is acquainted with the singular Miss Silver, who is only too pleased to be asked to investigate.
