Esmeralda Ahoy!

Things started to happen just when the four Lorrimers Robert, fourteen and a half, Sally, thirteen, and the nine and a half year-old twins were left in London with only their easygoing housekeeper in charge. First, there was the Esmeralda, a beautiful fifteen-foot sailboat bought with their combined savings. Then there was the thrill of exploring the Thames River from London down to the sea, with a small island as a campsite and general base of operations. And most unexpectedly, there was a mystery, involving the surly skipper of a river barge, his stealthy passenger and the river police. Skill, quick wits, and plenty of good humor were needed to keep the Esmeralda on an even keel as the Lorrimers coped with each exciting development of their journey. All the challenges of the sailing and a mystery are combined in an unusual adventure, described by two authors who know and love sail books and rivers.
