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 are lined with mansions and elaborate gardens. When several luxury estate homes 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.
