A substantial collection of brainteasers, mathematical puzzles, riddles and logical conundrums, dressed up as a magnificent medieval manuscript.

Fabrice Mazza brings together hundreds of problems designed to test reasoning, ingenuity and the occasional willingness to admit defeat. From dividing orchards into perfectly equal sections to rearranging matchsticks, solving numerical mysteries and navigating impossible-seeming situations, the puzzles range from approachable diversions to genuinely difficult exercises. Ivan Sigg's illustrations, elaborate illuminated lettering and parchment-style pages give the whole thing the appearance of a centuries-old book of intellectual mischief.

A beautiful puzzle book, equally suited to solitary obsession, competitive problem-solving or leaving open on a table to derail an otherwise perfectly civilised gathering.
