The Miracle At Speedy Motors by Alexander McCall Smith
THE NINTH BOOK IN THE BELOVED NO. 1 LADIES' DETECTIVE AGENCY SERIES
The one with the poison pen letter . . .
For the first time in her career as Botswana's no. 1 lady detective, Mma Ramotswe suffers a blow to her faith in the goodness of humanity (and of her neighbours in particular) when she receives a threatening letter. But she does not let this swerve her from the sad plight of an orphan who hopes to find her true family.
Meanwhile, at Zebra Drive, Mma Ramotswe's beloved husband Mr J. L. B. Matekoni is also searching for an expensive miracle for their own foster daughter Motholeli.
