The Perplexing Pineapple (The Cryptic Casebook of Coco Carlomagno and Alberta #1) by Ursula Dubosarsky

Coco Carlomagno is the well-respected, if somewhat easily startled, Chief of Police in Buenos Aires.

Alberta is his more sensible cousin.

Together they crack the cases that confound this puzzling city.

Coco Carlomango is sure his office high in the Obelisco is haunted. Every day he sees a floating pineapple and every day he hears a terrible noise. What could it mean?

There's only one guinea pig Coco can turn to for help: his logic-lovinng cousin Alberta. Can they solve the mysteries of the perplexing pineapple?

Read the mysteries, study the pictures, follow the clues and solve the puzzles in The Cryptic Casebook of Coco Carlomango (and Alberta)
