"The music box murders is more than a finely tuned dip into the New York antiques scene. It's an ode to the complex forces that drive a collector. It's an exploration of how honor and the love of beauty transcend class. It's a study of the mixture of fondness and irritation that dance around a couple as they listen to the swan song of their marriage. Larry Karp's first novel is all of these things, and still manages to tip its humorous hat to the quippy, clever P.I. novels of days gone by..... This book's tight, quick plot turns elegantly around small objects. The whole novel hangs plausibly around the travels of the rigid notation box..... This pace is maintained because Larry Karp manages to slip in his special knowledge of music boxes in a way that supports, rather than stalls the action. After devouring this novel, the reader suddenly knows more about music boxes, but doesn't remember having learned." (Sandy Faust, The mystery review, Vol. 7, #3).
