Watts and Pearl are back - and this time, they're on track to solve their trickiest case yet!

Tasked with guarding a fortune in stolen gold aboard the Midnight Express, the world's most secure sleeper train, the dog-and-cat duo are ready for anything. Or so they think . . .

When the train screeches to a halt in the middle of a snowy forest and the gold vanishes from the vault, all paws point to Patsy Caboose, the eccentric security goose. But something doesn't add up.

With suspects on board, clues in every carriage and a mystery that's going off the rails, can Watts and Whiskerton crack the case before the train reaches its final stop?
