A WALKING NIGHTMARE&#8212;IN SIZE-NINE STILETTOS . . . The officer responding to a 911 call at one of Houston&#8217;s hippest high-rises expected the worst. After all, domestic violence situations can be unpredictable. But nothing could&#8217;ve prepared him for what he found: a beautiful woman drenched in blood . . . an older man lying dead on the floor . . . and a cobalt blue suede stiletto with tufts of white hair stuck to its five-and-a-half-inch heel. With her stunning looks, magnetic personality, and erratic behavior, Ana Trujillo had a notorious reputation on the downtown Houston scene. She spoke often of occult powers, though few knew how deeply she believed such boasts. Stefan Andersson was a gentle soul, a Swedish transplant with a good career and trusted friends, who was desperate to find someone special. Theirs is a story of obsession, madness, and tragedy. Because once Stefan fell head over heels for Ana, he was under her control&#8212;and he didn&#8217;t have a chance in hell.
