In Plain Sight is the second book in the Ivy Malone series that I've read by Lorena McCourtney. The first was Invisible. These books are delightful cozy mysteries featuring Ivy Malone who is a "spunky widow with an unquenchable curiosity . . . and possum-gray hair."
From the Cover:
In her latest adventure, Ivy takes a secret trip to the Ozarks to elude some thugs who are seeking revenge. But her three-month stay on the lake of a small Arkansas town turns out to be more than just a getaway when a housekeeping job puts her at just the right time and place to exercise her amateur sleuthing abilities.
