Mistletoe and murder
(Junior Book)

Daisy Wells and Hazel Wong are spending the Christmas hols in snowy Cambridge. Hazel has high hopes of its beautiful spires, cosy libraries, and inviting tea-rooms - but there is danger lurking in the dark stairwells of ancient Maudlin College. Three nights before Christmas, there is a terrible accident. At least, it appears to be an accident - until the Detective Society look a little closer, and realise a murder has taken place. Faced with several irritating grown-ups and fierce competition from a rival agency, they must use all their cunning and courage to find the killer (in time for Christmas Day, of course).
