The delightful crime-solving and aristocratic social adventures of an American  antiques expert and a British feline with finesse

It's love at first sight when a businessman visiting London meets a silver-gray cat named James in the lobby of his apartment house. The two begin meeting regularly for cocktails—single-malt whiskey, neat, for James—and attending posh parties, where James first makes a name for himself by cracking the case of a priceless jewel scam.

Soon James is on the prowl, deterring pickpockets on the subway and ferreting out stamp forgeries and counterfeit paintings. In between crime capers, he screens potential tenants, spends the holidays at an ancestral estate in Devon where the crème de la crème of British society anoints him Sir James, and indulges in his penchants for pâté de fois gras and matchmaking with inimitable panache.
