The Lavender Butterfly Murders

Description for THE LAVENDER BUTTERFLY MURDERS by Sharon Duncan:

Scotia MacKinnon has survived two decades of law enforcement work, three marriages, and too many years of single parenting. She relishes her laid-back lifestyle on San Juan Island, but even in paradise, Scotia knows when to head temporarily for calmer water.

Frustrated by her deteriorating love life and the return of a long-absent ex-husband, Scotia opts for seven days of tranquility and therapeutic massage at a yoga retreat on neighboring Santa Maria Island. But all hopes of finding enlightenment are dashed when Scotia becomes embroiled in a nasty struggle between the spa's innkeeper and her rustic neighbors, a series of "accidents," and what looks like murder. As a brewing storm traps her on the island with terrified guests, Scotia calls on her earthly ingenuity--and some divine justice--to catch a vicious killer and restore everyone's peace of mind, especially her own.

This is #4 in A Scotia MacKinnon Mystery.
