Charming, old – fashioned art theft mystery
B. Johnson on Amazon.co.uk

This is a perfect old-fashioned but adult mystery. Real danger and threats of violence… but no explicit events of either kind. “Old-fashioned” in a 1930-40’s sense. Not Victorian. Think Cary Grant in a fast car with Grace Kelly. That’s the vibe. Highly recommend. Read before bed & go to sleep smiling.
