Lovejoy is a dodgy antiques dealer who lives in east anglia, and has a gift for knowing if an antique is real or not (this makes him a 'divvy'). this is the third Lovejoy novel i have read, and so far they have all followed much the same pattern. A friend of Lovejoy's is murdered, and it has something to do with some rare and very valuable antique. Lovejoy searches for the rqre antique, and tried to outwit the villains who are after it too. A number of women are usually involved, all crazy about him. Lovejoy nearly gets killed, but ends up killing at least some of the villains, and ends up in possession of the antique.
if you are familiar with the Lovejoy TV series, the books are quite a bit different, darker and more violent. Lovejoy himself is a much harder, more ruthless man than he is in the TV series. he treats the women who surround him casually, sometimes even brutally, but they all come back for more. His obsession with antiques is total, nothing else matters at all by comparison. Mysteriously, even with his remarkable gift, he always seems to be broke, i presume because he can't resist spending anay money he gets on still more antiques. but somehow, there is always a woman around to help him out. if you can suspend disbelief for long enough, the books are good fun.
