Lockwood & co., tome 1.5
Jonathan Stroud2013

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?

The Dagger in the Desk is originally an interactive 6-part story, a Halloween special, written by Jonathan Stroud, who wrote it in six days with the help from members of the Guardian children's website, who participated in polls during each part, deciding what elements to be featured.
