Pawełek i Janeczka znów starają się rozwikłać tajemnicę. Tym razem ktoś rozkopuje groby z czasów drugiej wojny światowej. W okolicy zaś szerzą się kradzieże bursztynu. Okazuje się, że te dwie sprawy mają ścisły związek. Jak zwykle niezwykle ważną rolę ma do odegrania Chaber, cudowny pies rodziny Chabrowiczów.
Joanna Chmielewska is the pen name of Irena Kühn (born 2 April 1932 in Warsaw), a Polish writer and screenplay author. Her work is often described as "ironic detective stories". Her novels, which have been translated into at least nine languages, have sold more than 6 million copies in Poland and over 10 million in Russia.
Joanna Chmielewska graduated as an architect in 1954 from Warsaw University of Technology, and worked as a designer before devoting herself to writing. Her first short story was published in the magazine Kultura i Życie (Culture and Life) in 1958 and her first novel, Klin (The Wedge), in 1964. She loves horse races and gambling: both hobbies have been mentioned extensively in her books. She is also a connoisseur of amber, a passion which form the basis for her 1998 novel Złota mucha (The Golden Fly).
To date, she has written more than fifty novels. Most frequently, the protagonist is a woman called Joanna that inherits many characteristics from Chmielewska herself. She also often writes about Joanna's friends like Alicja (We Are All Suspects, All in Red), co-workers (We Are All Suspects, Wild Protein) or family (The Forefathers' Wells, Bad Luck).
