Who stole the one and only Black Throumba?
One-eyed mathematician Octavio Puzzle is called to solve the mystery of the disappearing Black Throumba olive — one and only, irreplaceable, and very much gone. Armed with logic and a mind for numbers, he sets out to crack the case. But can reason really explain everything?
A delightfully quirky whodunit full of eccentric characters, philosophical riddles, and the kind of humour that makes you think. A book that proves mathematics can be the greatest adventure of all.
