Jardine, Quintin: Inhuman Remains: A Primavera Blackstone Mystery

Her mind still filled with thoughts of Oz, her dead ex-husband, Primavera Blackstone is in Spain with son Tom when their peace is breached with the arrival of her elderly but formidable Aunt Adrienne. All is not well in Auntie's world: her roguish son Frank has become involved with a shady international casino project and has disappeared. Primavera flies to Seville to track him down only to find herself a fugitive with her life under threat. Aunt Adrienne then joins the missing persons list, and Tom is forced to flee to safety. As Primavera crosses Spain in a struggle to stay alive and free Adrienne, she soon finds herself at the center of a maelstrom of mystery.
