Lockwood & Co: The Dagger in the Desk

A thrilling new case for London's most talented psychic detection agency - from the global bestselling author of the Bartimaeus Sequence.

In London, a mysterious and potentially deadly ghost is stalking the halls of St Simeon's Academy for Talented Youngsters. It lurks in the shadows, spreading fear and icy cold - and it carries a sharp and very solid dagger . . .

The headmaster wastes no time in enlisting the help of ghost-hunters Anthony Lockwood, Lucy Carlyle and George Cubbins.

Can Lockwood & Co. survive the night and save the day?
