As a consequence of an air crash which leaves him partially disabled, Jerry is advised, by his doctor to go take some rest in the countryside.
His sister, Joanna, finds them a small corner of paradise, in Lymstock, Little Furze property of the Barton sisters. Emily being the only survivor, agrees to rent them.
A quiet place in appearance, where nothing badly could happen to them.
But hardly one week later, the hamlet will deliver its terrible secret : a crow.
Oh! Not the usual kind of blackmailer, one who invents grotesque charges instead of using the true secrets of the inhabitants.
While speaking about it with people of the village, Jerry learns that he strikes on all the levels of Lymstock’s society , that nobody is safe.
If it wasn‘t for the imminent danger, one could almost laugh of such nonsense.
Indeed, although completely unrealistic, the blackmailer’s revealed secrets could as well be true.
When Mrs Symmington, the wife of the notary takes her own life, what started as a joke became an awful incitation to commit suicide.
Who is the blackmailer?
Who wanted to see Mrs Symmington die?
Miss Marple, once more, will show that its reasoning on the human nature is correct.
She will have to learn to know the protagonists and to examine their personality, to confound a very clever assassin.
Dr. Owen Griffith which seems to have a crush on Joanna, that the crow suspects to disrespect professional ethic with his patients.
The notary Mr. Symmington, shown to have a guilty connection with its secretary.
The secretary of the notary miss Ginch.
Partridge, and Florence usually working for miss Emily Barton, remaining in Little Furze to help Jerry and Joanna.
Megan Hunter, step girl of Me Symmington, born during the first marriage of its wife.
Put aside, her parents prefer her half-brothers Brian and Colin.
Miss Griffith, the doctor’s sister, chief of the city guides.
Mr. Pye, the effeminate amateur of antiques.
Elsie Holland, teacher of the Symmington children.
Mrs Baker, the mother of Beatrice who had left the service at Little Furze because of the calumnies made on her account.
The reverend Caleb Dane Calthrope and his wife.
All can have done the irrevocable.
It is by analysing the human nature of the inhabitants of Lymstock, not so different from those of St Mary' S Mead, that Miss Marple will see clearly.
And once more will manage to make the light on the personality of an unusual murderer.
Jerry, will learn, at his own risks that countryside is far from being the resting haven of peace that he expected.
