The Third Key — Steve Elliott

The search for the third key has begun. However, before it starts, his friends finally learn about the emotional demon that has haunted Jack, and caused his traditional antipathy towards girls. Jenny, Jack, Justin, Whiskers and Feathers then make their way to the place where the key is believed to be hidden. But, along the way, they encounter something horrendous which triggers a very odd event. It's so odd, in fact, that everyone has trouble believing it. Despite this, they carry on and arrive at the supposed resting place of the third key. Once there, they discover their mission isn't as easy as they would have wished, because the key is well and truly hidden. However, they hatch a plan to use a most remarkable method of finding it. Time is of the essence, because the threat of the rats is ever present, and their luck may be finally running out.
