Part of the author's Homer/Mary Kelly series of mysteries based in Concord MA. The plot centers on a crystallographer falling in love with a stranger at an exhibit of Escher work, and his enlisting the Kellys' help to find her. The novel contains frequent allusions to the mathematics in Escher's artwork.

A very disappointing book. The plot is weak, full of cliches. I found the metaphors and comparisons with work by Escher *really* bad literature. Really regretted having picked it up, but the title sounded nice.

I love Jane Langton's books, and she gives you a love for the topic. In this case, a bit of geometry (as relating to Escher.) Not bad lit at all--it's nicely, simply written, with charming characters.

A fun and entertaining book if you like cozy mysteries. I enjoyed the inclusion of Escher's work and drawings.
