It's a week before Christmas and Hettie and Tilly set out on a very dangerous case for The No. 2 Feline Detective Agency. Lady Eloise Crabstock-Singe has summoned them to Crabstock Manor in the village of Porthladle on the Cornish Coast to solve the mystery of Christmas Paws, a servant cat who haunts the Manor intent on killing off all the Crabstocks.

Should they put their trust in Absalom and Lamorna Tweek? Will Saffron Bunn's cooking get any better? And what is Evergreen Flinch searching for?

Through blizzard and storm, stranded on the notorious Bodkin Moor and laid up at Jam Makers Inn will Hettie and Tilly save the day and get home in time for Christmas dinner?
