Agaton Sax and the Diamond Thieves
by Nils-Olof Franzén; ill. Quentin Blake; trans. Evelyn Ramsden (Andre Deutsch, 1965)
The fourth book in Franzén’s detective series but the first in English translation. Agaton Sax retains his customary self-assurance, yet the story in this instance seems a little extemporised and so he ends up in pursuit rather than mastery of the plot.
