Book excerpt: YOU'D BETTER WATCH OUT. YOU'D BETTER NOT CRY. SANTA CLAUS IS GOING TO DIE...DCI Boaz Matthias isn't a Christmas person. He never has been. Not since he discovered the truth when he was seven. Christmas is a lie and a con and nothing is ever going to change his mind. Being given a temporary six week assignment isn't helping his mood either—as it means Christmas with the family. Only good thing is the accidental meeting of someone he thinks he could grow very fond of. DC Isabel York loves Christmas. So much so that she decorates her desk with lights, tinsel, and a novelty advent calendar. When her boss is called away, his replacement is the last person she's expecting to see—her fledgling boyfriend. In the middle of a nasty case, Isabel is nevertheless determined to show Boaz the real meaning of Christmas. The only problem is that work and pleasure just don't mix—at least not according to him.
