Jonathan Argyll Art History Mysteries

When Jonathan Argyll is arrested for breaking into an obscure church in Rome, he claims that it contains a long-lost Raphael hidden under a painting by Mantini. The painting disappears - then reappears in the hands of the top British art dealer, Edward Byrnes. How has Byrnes found out about the hidden masterpiece, and whom is he acting for? There is also the curious matter of the safe deposit box full of sketches closely resembling features of the newly discovered painting.

In an exchange of favors with an art dealer colleague, Jonathan Argyll unluckily offers to transport a painting from Paris back to Rome. It seems routine work, and Jonathan gets to meet his girlfriend, Flavia, who works for Rome's Art Theft Squad. But when a would-be thief tries to take the painting at the train station, and the art dealer seems less interested in his purchase once he sees it, Jonathan wonders why, as events unfold, someone is willing to kill for it.
