Ortega sighed. 'Kovacs, I went over that house myself three times with the forensics team. There's no sign of a struggle, no break in the perimeter defences and no trace of an intruder anywhere in the security net's records. Miriam Bancroft volunteered to take every state-of-the-art polygraphic test there is and she passed them all without a tremor. She did not kill her husband, no one broke in and killed her husband. Laurens Bancroft killed himself, for reasons best known to himself, and that's all there is to it. I'm sorry you're supposed to prove otherwise, but wishing isn't going to make it fucking so. It's an open-and-shut case.'
