Sisters at an Exhibition is a delightful addition to the Zara and Lilly series, blending modern sleuthing with historical echoes in a way that feels both playful and surprisingly poignant.

The disappearance of a possible Caravaggio sketch—and the curator who was studying it—sets the sisters off on a globe‑spanning chase. Zara’s sharp, lawyerly pragmatism pairs beautifully with Lilly’s irresistible flair for trouble, romance, and the occasional questionable decision. Their dynamic is warm, witty, and wonderfully human, making them the kind of sleuths you want to follow anywhere.

The mystery itself is layered and engaging, moving from San Francisco’s art scene to New York and finally to the atmospheric countryside of Alsace. The WWII journal entries threaded throughout add depth and texture, enriching the central puzzle without ever slowing the pace. By the time the story converges in the old barn where secrets may—or may not—be hiding, the tension is delicious.

This is a cozy mystery with sophistication: mature protagonists, sharp humour, and a plot that balances charm with genuine stakes. Fans of character‑driven mysteries and art‑themed intrigue will find this an utterly enjoyable read.

If you love sleuths with personality, puzzles with history, and stories that travel, Zara and Lilly are a treat.
