There are two principal characters in this novel: Father Lorenzo Quart, worldly, sophisticated official of the Vatican's most secretive department, and the city of Seville, superbly recreated on the page by Perez-Reverte. The minor "low-life" characters are worthy of a Shakespearean comedy -- one thinks of Dogberry. This is a novel of atmosphere and detail rather than plot, which while inherently intriguing does become rather stretched at the last, but the novel remains highly enjoyable. One might wish that the author had not felt it necessary to highlight the supposed flaws in Fr. Quart's otherwise deeply attractive persona (he must the most handsome Catholic priest ever to wear a clerical collar), and the central plot's denouement is barely credible, but they are details that do not detract unduly from the real centre of the novel, Seville itself. The incidental insights into the workings of the Vatican are illuminating, and often amusing: the author is clearly no fan of the Polish contingent that surrounds the Pope. Just the thing for a long train journey or a grey, wet weekend.
