San Francisco is home to more than 200 privately owned streets. Most are alleyways, but a select few look torn straight from the pages of a magazine. Lined with mansions and elaborate gardens, the properties are luxurious and perfectly maintained; security guards patrol the grounds to keep the curious at bay. Few know of these exclusive enclaves, but those who do prowl for availability, ready to make a grab for the precious real estate if opportunity strikes.

When several such streets are targeted in a series of so-called pranks, Sharon is hired by a coalition of concerned owners to investigate. But as things escalate--an attempt on Sharon's life, an explosion at a meth lab, and a shocking murder--Sharon realizes far more is at play than a few misdemeanors gone wrong.

The case takes a sudden turn when one of McCone & Ripinsky's most trusted employees is implicated, and Sharon will have to dig deep to save her agency--and her life.
