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 the Cornish coast to solve the mystery of Christmas Paws: a servant cat who haunts the family manor intent on killing off all of the Crabstocks.
Should they put their trust in Absalom and Lamorna Tweek? Will Saffron Bunn’s cooking get any better? And will Hettie and Tilly get home safely in time for Christmas dinner?
