Charlie and Gus, brother detectives, are at school in America, but spend every holiday aboard the English houseboat of their Aunt Allegra, moored in the north Essex village of Rowhedge.
This time, only days after the boysÕ arrival, Mr Admiral, the most celebrated, elusive and smelly resident of the village, is found murdered. His wife is distraught. Who has killed Mr Admiral?
