Shop Till You Drop

Description for SHOP TILL YOU DROP by Elaine Viets:

Once on the fast track to success, Helen Hawthorne is going nowhere faster. Forced to trade in her chic life for a shabby one, she's now on the run, jumping from city to city and dead-end job to dead-end job, trying to stay one step ahead of her past...

After two weeks as the new salesclerk at Juliana's, Fort Lauderdale's ultra-exclusive clothing boutique, Helen still feels out of fashion. But in a shop where the customers' collagen lips are bigger than their hips, who wouldn't? And since the only crime likely to be committed around here is being old--or worse, looking old--Helen figures she's safe. Until she discovers the manager has been embezzling money and selling designer drugs along with the designer clothes. Add murder to the mix and Helen is in trouble. To protect her secrets, she will have to solve the case herself--before her dead-end job turns deadly...

This is #1 in A Dead-End Job Mystery.
