Amusing and diverting melodrama. A short tale of mistakes, secrets and hidden relationships. The Darnel family seem to live an idyllic life until a shocking crime is perpetrated on one of the household. Scotland Yard is called in, but a family friend intervenes to prevent scandal ruining the family. It's pretty clear from the outset who is guilty, but you stick around to see how the secrets and lies are resolved - which they are, and very speedily, to fit within the 126 page tale.
