Daisy Wells and Hazel Wong are spending the Christmas hols in snowy Cambridge. Hazel has high hopes of its beautiful libraries and inviting tea-rooms - but there is danger lurking in the dark stairwells of ancient Maudlin College.
Two days before Christmas, a brutal accident takes place - but the Detective Society suspect murder. Faced with 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).
