In this sequel to The Lanvin Murders, Portland, Oregon, vintage clothing store owner, Joanna Hayworth, is in a tight spot. Her plans to upgrade her store have derailed, and costs are mounting. When she wins three trunks of vintage haute couture at auction, she thinks her luck has changed, but it's about to get much worse. The clothing's high-society matron owner turns up poisoned, and police seize the wardrobe, leaving Joanna with mroe debt, a friend wrongly jailed for diamond theft, and a convent of quirky nuns depending on her help. There's only one way to calmer waters: find the murderer, and fast.
