The Improbability of Love by Hannah Rothschild is a gripping look into the modern art auction world. It takes place in London, and features a painting with opinions along with other skillfully developed characters. WWII plays a role, with haunting back stories of those who lost their art to the Nazis. The heroine is a caterer who accidentally stumbles upon a Watteau, buys it and is engulfed by those desperate to do anything to have it. Motivations vary, but greed and the preservation of family secrets figure prominently. This was a real page-turner.
