Lots of interesting information about music boxes. Interesting characters: a twitchy synesthetic skylight burglar (he sees sounds), a post-stroke music box restorer/builder who needs assistance, a way shady dealer, an overlooked dealer, and more. Sleuth, an academic neurologist, seems to have more time available than any academic-type I've ever known. Plenty of time to solve the crime(s), fortunately for the story. Thomas' solution achieves justice for most and hope for many. The bit with the silk painting was confusing, but apparently each person got what he/she needed/deserved.
