"Ottoline and Mr. Munroe love puzzles, clues and mysteries. One day, they meet an enigmatic purple fox, who offers to take them on a night-time urban safari.

Mr Munroe is making notes too --on the anonymous poems he finds stuck to lampposts on their journey. Who is the secretive poet, and how can he and Ottoline help them mend their broken heart?"--OCLC.
