Killer Keepsakes by Jane K. Cleland

Josie's assistant, Gretchen, has always been extremely reliable. When Gretchen doesn't show up for work after her vacation in Hawaii is over, Josie knows something is amiss. She decides to go over to Gretchen's condo to see if she can find out what happened. After discovering a man's body on the couch, Josie becomes even more worried for her. A missing vase and a unique belt buckle the dead man was wearing provide some of the only clues for Josie to try and locate Gretchen. Josie knows that Gretchen is not a murderer and wants to help her clear her name. But when Josie's reporter friend Wes finds out that Gretchen has been using a fairly recent social security number, Josie wonders about Gretchen's past and who she really is. Killer Keepsakes is another solid entry in this cozy antique mystery series.
