‘Stop, foolish woman!’ Fogarty barked, stepping in front of the cage ‘Dody, be careful,’ Pike warned, putting a hand on her arm. She counted to ten and took some deep breaths. She must not lose her head. ‘It’s all right, Pike,’ she said calmly. ‘I know all about this kind of instrumentation. It’s a Faraday cage, used for electrotherapy. Doctor Lamb told me all about it and various other electrotherapy treatments on the telephone yesterday.’ She also noticed the polished box she had seen in Fogarty’s office. When she’d described it to Lamb he’d told her it was a Clerk’s machine, used to discharge low doses of electrical voltage directly into the human body. She tried to push past Fogarty to reach her sister, but he stopped her with raised hands. ‘No, I don’t think you do know all about it, Doctor McCleland. Not this one, anyway.’ There was something about his tone that made Dody stop in her tracks. ‘According to Doctor Lamb this kind of contraption is harmless,’ she told Pike, her eyes never leaving Fogarty’s.
