Chocolate-loving penguin detective Mr. Pin is relaxing between cases when a client approaches him with a baffling problem-someone is smashing the stone gargoyles in his warehouse. In fact, all over Chicago, gargoyles are falling from the buildings. Hoping to stop the villain before someone gets hurt, Mr. Pin and his young friend Maggie scamper to the latest crime scene to collect clues. But when an empty chocolate box is found near a destroyed statue, and a rock hopper penguin is seen scuttling away, police blame Mr. Pin. The flippered detective must find the culprit-quickly-or lose his reputation and more. As he munches his way through the chocolate clues in two exciting cases, Mary Elise Monsell's loveable penguin from the South Pole teaches that appearances can be misleading. Narrator John McDonough will have young listeners laughing out loud with delight as Mr. Pin finds the statue smasher and solves a second puzzling mystery for the famous Cubs baseball team.
