Shakespeare is an agent with the British Secret Service.
Not the playwright, of course. The cat. Well, a cat but definitely a special cat.
We are told of this young, frisky little feline that "Shakespeare was a loner. He only looked out for number one now." Which, to me being a cat owner for many, many years, is like stating the obvious. Of course cats look out for number one. Now and always. They're cats! It's like saying fish swim.
What makes Shakespeare so special to us is that he has the fortuity to live in the same household as Lara. If he didn't we would not know about him and this page in the compendium would not exist. But he does and Lara does and so on occasion, when Lara and her brood are called away from their assigned posts of watching over the Cook family, Shakespeare finds himself pushed into service.
So to understand Shakespeare we have to understand Lara, the dog in the same household. Lara is really LARA, which stands for 'Licensed Assault and Rescue Animal' and she is "a highly trained special agent, bred by the British Secret Service for use on dangerous missions throughout the world". When we meet her, she had found herself captured and thrown into a kennel and there her training taught her to act like any other dog and get adopted so she chose the Cook family and how uses that home as her base. Her and her subsequent offspring.
But they are all really British agents who get called away for training or briefings or whatever dog agents do when they are not at home. And since trouble does not go away just because Lara and company do, well, Shakespeare is there to take on the job!
