Mice of the Westing Wind, Book Two1999

In the next instant, Oliver heard Merton's squeal of rage. "It's them -- it's the mice." Charles and Oliver scrambled up the rigging, but the rats came right behind them, gaining step by step. Higher and higher they raced, until they reached the wooden platform near the top of the mainmast. Charles and Oliver set a trap for the pirate sea dogs, and with the help of Captain Tabby, they plan a final attack. But two fierce rats are determined to destroy Charles and Oliver, no matter what. - Back cover.
