Shirley Link loves pirates. Well, she loves the idea of them. She wouldn't like them if they were running up the street stealing bikes. But digging for treasure and swashbuckling adventure are on the top of her to-do list. So when a clue pops up that there's a hidden pirate treasure under her hometown, Shirley gets to work. In Shirley Link & The Treasure Chest, the third volume in the critically-acclaimed Middle-Grade Mystery series, our heroine takes on her biggest challenge yet. But this time the stakes are higher than ever. If she fails to find the treasure, or if it ends up being a hoax, then Shirley's elderly neighbor, Mrs. Smiley, will lose her home to the bank.
