Thirteen-year-old Duncan lives with his unconventional bohemian aunt. She's determined to give him an expensive private education, even though Duncan isn't particularly interested in school. He wants to be a detective like the ones in the World's Best 100 Detective Stories, which he reads when he should be studying. Full of twists and turns, laugh-out-loud adventure, and even a cobra and an alligator, Duncan gets his chance in this fast-paced romp loosely based on a true story from Texas in the early 2000s.
