Pirate fever sweeps through town after an opportunistic treasure hunter shows up looking to lay claim to Blackbeard's lost gold buried somewhere in Tupelo Landing. When the (probably) world-famous Desperado Detectives - Mo and Dale and Harm - are hired by Mayor Little's mother to find the pirate loot for her, the high-stakes race for riches is on!

But that's not the only treasure hunt in town. Mo LoBeau unearths shocking new clues that may lead to her long-lost Upstream Mother - in the riskiest, scariest, and possibly richest case of her life.

The Law of Finders Keepers can be read right after Three Times Lucky. And don't miss the other Mo & Dale Mysteries, The Ghosts of Tupelo Landing and The Odds of Getting Even!
