Frost at Christmas is the first book in this delightful six book series. Frost is introduced as a befuddled, conniving, sarcastic, and insolent cop, promoted beyond his capabilities, who tackles crimes seemingly without rhyme or reason. Every one of his actions seem designed to be as inefficient as possible and annoy those around him, yet Frost receives loyalty from most of his colleagues as, at heart, he's a lovable rogue whose two commitments are to catch the bad guys and to share any plaudits. Wingfield's characterization is excellent, with every character well penned. The writing is light and comic, the story racing along at a cracking pace. My only gripe was the improbability of the interconnections between the plotlines, which were really not needed as what ties the strands together is Frost, not spurious sub-plots. Frost at Christmas was an entertaining read.
