Mystery of the Third Lucretia by Susan Runholt

Two friends, Kari and Lucas, travel the world with Kari's mother and in the process they stumble across an art crime that involves lies, forgery and murder. The two girls observe, disguise themselves, and get kidnapped but they solve the crime when no one but a few would believe there was a crime to solve. It was a fun light read but part of the mystery is the discovery of a third Lucretia painting by Rembrandt and everyone thought it was real just by the composition and style of the painting. I kept thinking "what about scientific testing of the paints?" and I had a hard time getting past that discrepancy even though I know it is only a book. In the end, it was a decent mystery. Good, not great. nay.
