For Bob, lying on the sofa, watching "mindless television, just letting it wash over me", was all he could do. "I couldn't watch television. In fact I very rarely do now," says Sally, "because there was always something that would set me off, a drama or the news. Sometimes it still takes me by surprise when the video of Milly ironing is shown on TV. That can be really hard." The footage, which has become poignantly familiar to many of us, was filmed only two days before she went missing.
