Fox and the Mystery Letter
Frances Lincoln (August 2025)
Fox has a mystery to solve – and a friendship to fix!
In the dense forest, in a lonely cottage, there lives Fox. Fox is perfectly happy all by himself – until one day, a letter arrives: "Dear Fox: I know how much you enjoy puzzles. I bet you can’t resist this one . . . Head to the forest path to begin your journey. From an old friend."
Fox doesn't need any mysterious puzzles, adventures or memories of his old— But he stops himself from finishing the thought. Still, it can't hurt to look at the first clue. Of course, one clue leads to the next: Fox follows arrows in the mud, notes taped to trees, swirling smoke signals, a map from a bottle and gifts from fellow animals – on the trail of a friendship that once was.
Author-illustrator Alex G. Griffiths creates an irresistible mystery for readers to solve in this witty, whimsical picture book – with important themes of friendship, forgiveness and opening up about your feelings.
