I must have checked this book out from my school’s library every other month. The other book I checked out obsessively was full of graphic photographs from the Holocaust. I was a strange kid.
Description from Amazon: “When Horace the Elephant decides to throw himself a party for his 11th birthday, he never suspects a crime will be committed by lunchtime. Who has stolen the birthday feast? As with any good mystery, everyone is guilty until proven innocent. The proof lies in the myriad clues embedded in each glorious illustration. Young sleuths will delight in decoding the complex messages that pop up in unexpected places.”
