The Mysterious Visitor

Here's the much-anticipated third book in Joan Weir's bestselling YA mystery series starring a bantering brother-and-sister team named Lion and Bobbi. The Mysterious Visitor begins when their lawyer Dad is called away to a suspicious case involving an old friend and a mysterious crop circle on his environmentally sensitive land. Lion and Bobbi accompany their Dad on his business, promising to stay out of trouble ... but of course, that doesn't last for long. Before the end of the book, the amateur sleuths have brought together two pairs of lovebirds and even exposed the crop circle as a hoax ... maybe!
