The only reason I didn't give this (highly enjoyable) mystery five stars was that I felt that the occasional "neuroses" of Anne to be a little far-fetched... it is unclear WHY she insists that her space is being invaded and why she sometimes acts the way she does. This may be clear to those who have read her other books though. I really enjoyed the mystery itself--especially the way it was built from a simple job (install security) to a full fledged puzzler. The story is always interesting to follow and the author has a real ear for dialogue and phrasing--plus, the descriptions of her neighbors are great. All in all, worth reading
