The Secret of Sagawa Lake

Join Sam, Dog Detective, on her sixth adventure as she spends some quality time communing with nature. A whole weekend away at an island cabin in the woods. Could anything be more boring? Sam knows she'll never find a good mystery in a bunch of trees. But when the sheepdog sleuth and her friends, Jennie and Beth, discover an old diary, the age-worn pages reveal some surprising secrets. Now Sam is sure there's a monster in the lake, and she's determined to track down its watery lair.
