When will Jonathan Argyll learn? This time, the budding international art dealer with a nose for trouble volunteers to deliver a minor French painting to its new owner in Rome, only to find on his arrival that (1) the buyer, Arthur Muller, no longer wants it; (2) by the next day Muller's been tortured and killed; and (3) back in France, the canvas has been reported stolen. Even as Argyll's tracing the painting's ties to the ugly betrayal of a Resistance cell in wartime France, his unofficial fiancÇe Flavia di Stefano, of Rome's Art Squad, is getting ready, as usual, to save him from his own impetuosity—and from more of the worst judgment boasted by any fictional detective outside the funny pages. Though the flashback to historical intrigue barely 50 years old is something of a novelty for Pears (The Bernini Bust, 1994, etc.), Argyll and Flavia's fourth is as densely plotted as ever.
