Next Week Will Be Better — Jean Ruryk

DEATH BARGAIN
Getting out of bed at four in the morning to spend weekends rubbing shoulders in the summer heat with flea market hagglers isn't furniture restorer Cat Wilde's idea of fun. But she couldn't refuse friend Rena, who needed someone to run her table at the flea market while she recuperated from surgery.

Luckily she had the space next to Old Sam, an acquaintance and true flea market diehard. But spotting a menacing character and a wad of bills being passed under the table, Cat suspects Sam is in some sort of trouble. When he's murdered, she starts digging into the discordant world of the flea market hierarchy, and discovers it's not who you are-- it's what you sell.

And that there are those perpetually seeking the buried treasure in the piles of junk -- dealers, collectors, investors. People who will do anything for a bargain. Even kill.
