No Place Like Holmes by by Jason Lethcoe

Twelve-year-old Griffin Sharpe prides himself on his gift for observation. When he visits his uncle, a private detective living at 221 Baker Street in London, Griffin is sure Uncle Snodgrass is the great Sherlock Holmes. Instead, he finds his uncle lives at 221A Baker Street and bears a grudge against the more famous detective in 221B. Griffin will need all his astuteness and the power of prayer to win over his uncle and solve a mystery before the summer is through. The fast-paced story will keep you reading until the very last turn of the page. Ages 9-12. (Thomas Nelson)
