The Rat-A-Tat Mystery

How can the door knocker go rat-a-tat by itself?
A cosy house surrounded by snow-covered hills seems the perfect place to spend the Christmas holidays, but the peace is disturbed by unexplained noises. Who could have
knocked at the door in the middle of the night? There are footprints in the snow, but nobody there! And what is it that Snubby can hear coming from the cellar? Snubby goes
to investigate – and mysteriously vanishes!
Barney, Roger, Diana and Snubby love solving mysteries and this is their fifth adventure!
The Barney series (also called the Barney ‘R’ Mysteries because each title begins with the letter R) is all about siblings Roger and Diana Lynton, their cousin Snubby and their circus friend Barney. Together, the four, along with their pets Miranda the monkey and Loony the spaniel, embark on all sorts of adventures – from cracking curious cases to busting smuggling rackets.
