Expat Zoe Barlow has settled well into her artist's life among the Lost Generation in 1920s Paris. When a too-tipsy guest at her weekly poker game breaks Zoe's favorite clock, she's off to a Montparnasse flea market to bargain with the vendor Laurette for a replacement. What Zoe didn't bargain for was the lost Chagall painting that's been used like a rag to wrap her purchases! Eager to learn whether Laurette has more Chagalls lying about like trash, Zoe sets off to track her down at her storage shed. With no Laurette in sight, Zoe snoops around and indeed finds several additional Chagalls—and then she finds Laurette herself, dead beneath a scrap heap, her beautiful face bashed in.

With Paris hosting the 1924 Summer Olympics, the police are far too busy with tourist-related crimes to devote much time to the clock seller's murder. After returning the paintings to a grateful Marc Chagall, Zoe begins her own investigation. Did the stolen paintings play any part in the brutal killing? Or was it a crime of passion? Zoe soon discovers that there were many people who had reason to resent the lovely Laurette. But who hated the girl enough to stop her clock permanently? When Zoe discovers a second murder victim, the pressure is on to find the killer before time—and luck—run out.
