'These attacks are not merely pranks or accidents,' said Daisy Gravely. 'These are intended - and I believe something truly terrible will happen before Christmas Day.'

Daisy Wells and Hazel Wong are spending Christmas holidays in the snowy Cambridge. Hazel has high hopes of its beautiful libraries and inviting tea-rooms - but there is danger luring in the dark stairwells of Maudlin College. Two days before Christmas, a brutal accident takes place - but the Dectective Society suspect murder. Faced with fierce competition from a rivel agency, they must use all their cunning and courage to find the killer (in time for Christmas Day of course!).
