That evening, a little after eight o'clock, Peace observed Mrs Dyson coming out from her back door and entering a nearby outhouse. When she duly emerged, he confronted her with a revolver, shouting "Speak or I'll fire." In terror, she retreated to the outhouse, and her husband came out to investigate. Peace fled down the passage, where Dyson followed him. Peace fired twice at Dyson, the second shot passing fatally through his temple. As Mrs Dyson cried "Murder!", Peace escaped and made his way by train to Hull, where his wife kept an eating-house.
