Circle in the Water — Marcia Muller

In this twisting mystery in a New York Times bestselling series, pranks escalate into a deadly scheme that Private Investigator Sharon McCone must unravel -- ​before they claim her life.

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.
