Careful What You Wish For by Hallie Ephron

Professional organizer Emily Harlow gets more than she bargained for when she gets two new clients, Mrs. Murphy and Quinn Newell. Mrs. Murphy wants Emily and Becca (her partner in their business, Clutter Kickers) to help her sort through her husband's possessions (he died a year ago), especially the storage locker he rented. Quinn wants Emily and Becca to help her get rid of all of the stuff in her garage that she hasn't touched since she married. When Quinn's husband, Walter, is found dead and the items in Mrs. Murphy's storage locker turn out to possibly be stolen, Emily finds herself questioned by the police, not knowing whom she can trust. Emily's marriage is also strained by her husband Frank's obsession with collecting more and more objects, verging on hoarding. Careful What You Wish For is a softer-edged suspense novel perfect for those who enjoy Mary Higgins Clark.
