The wolfhound of the freighter Lady Anetta is a ghost story that’s been told for generations in Schooner Cove. It is said that the hound is a herald: once it has shown itself, death will soon come to call. Cecilia, Leo and Une all see a big, black stray dog wandering out on the mountain plain. The following day, one of the guests at the guesthouse The Pearl hostel is found dead.

The CLUE gang don’t believe in ghosts, or at least not that a ghost dog would leave tracks in the snow. As they follow the trail, they end up deeply entangled in one of the most perilous mysteries they have encountered yet.

The CLUE series’ name comes from the first letter in each protagonist’s name: Cecilia, Leo, Une, and Une’s dog Egon. In each of the series’ books a new mystery and a new ethical question is introduced along with the thoughts of one of the world’s most well-known philosophers. The CLUE books are best selling crime fiction for younger readers aged 9-12.
