The Secret Detectives

The body seemed to fall for a long time. There was no splash, or if there was it was lost in the waves. Isobel was frozen to the spot for a moment - and then her common sense caught up with her, and she stepped back quickly into the shadows.


On board the S.S. Mariana, Isobel Petty witnesses a shocking act - somebody being thrown overboard in the middle of the night. But when the ship's captain insists that nobody is missing, Isobel and her reluctant new friends must solve two mysteries - the identities of both the murderer and the victim - before the ship reaches England and the culprit has the chance to escape.


A hugely gripping historical mystery from an incredible new voice in children's fiction.
