Dr. Katie Martin saw death twice in one day: just after her vain, unstable sister plummeted from her Washington, D.C., apartment; and then again, when she looked into the smoky gray eyes of the man who'd haunted her dreams for eight years. Biotech researcher Mac McQuade had once banished Katie from his life--but he couldn't now. Now he needed answers to the suicide of his partner, a man who'd grown more irrational the more he got involved with Katie's beautician sister. As Mac and Katie probed the high cost of beauty in the salons of the nation's capital, the madness circled ever closer. For they weren't the only ones vitally interested in the twin tragedies--only the most vulnerable.
