NO WAY OF TELLING

The title presumably refers to the well nigh inexplicable, and certainly unbelievable, presence in the snowbound Welsh hills of a Spanish-speaking sailor (who has information about a plot to overthrow the Peruvian government) and the two ski-equipped international criminals (aliases Catcher and Nabb of Scotland Yard) who are pursuing him. If you're willing to take the initial leap you might take some interest in Amy's plans to escape from her Granny's isolated cabin -- which Catcher and Nabb have made their headquarters -- and her perilous toboggan ride through the blizzard threatened hills to the nearest farm. But then it's necessary to accept the fact that the Peruvian ambassador has arrived on the scene and taken lodging in that very farmhouse, and that Amy's bravery is rewarded with the very present she had been longing for -- round trip tickets for her and Granny to visit her father in Australia. Considering the endless, insipid conversations between Amy and Granny which pad the story to beyond-average length, it's hardly worth the effort.
