Formerly a river urchin living on the banks of the Thames, nine-year-old Worm has never experienced a family Christmas. But thanks to Hester Monk's clinic, he's found a makeshift family in kindly volunteer Miss Claudine Burroughs and curmudgeonly old bookkeeper Squeaky Robinson. When Worm witnesses the abduction of a beautiful woman just days before Christmas, he frantically turns to Squeaky for help. What neither of them expects, however, is that the damsel in distress already has her dilemma well in hand. But the kidnappers, as cunning as they are deadly, are not to be underestimated.
