Halliwell’s declaration then goes on to say that on Monday, January 9, Ivy Matthews called at his house in Gore Street, Fitzroy, and told him that she had told the detectives that he had made a key for Ross. Halliwell said: “That is untrue.” It is important to remember that, at this time, the problem of how Ross, if he were the murderer, got back to the Arcade, was troubling the detectives, and Matthews appears to have come forward with a suggestion, for she knew that Halliwell was a locksmith. Matthews then said: “I want you to tell the detectives you made a key,” and she said that she also wanted him to tell the detectives that he was in the saloon on the Saturday, and asked Ross if he knew anything of the murder, and that Ross replied: “I have never been a ‘shelf’”—a “shelf” being, in criminal language, an informer. Matthews then said to him: “I’ve got a friend down at the corner in a motor, who is very much interested in this case, and I want you to tell him what I have said to you.” He accompanied her to the corner of Westgarth Street, where he found Detective Piggott in a car. Piggott directed him to sit in the front seat with the driver, and Matthews got up beside Piggott on the back seat. Piggott after a time said to him: “What about those keys?” and he replied that he knew nothing about them. Piggott said: “I want you to come to the Detective Office with me,” but Matthews said: “I want to see him this afternoon.” Piggott and Matthews had a conversation, and then Matthews said to Halliwell: “I want you to meet me at the corner of the Queen’s Mansions at 3 o’clock this afternoon,” and when Halliwell said he did not know where they were, she explained that they were at the corner of Rathdown and Victoria streets. He then got out of the car, and later he met Matthews at the time and place appointed. She took him to her house, supplied him with some drink, and then said: “I don’t want you to slip in anything I told you this morning; why did you tell Piggott you never made the keys?” Halliwell said: “I was only telling the truth when I said it.” She then sent him to the Detective Office, where he was questioned by Piggott and Brophy. When he said he was at the saloon on the Friday Piggott said: “No, it was on the Thursday,” and told him he was also there on the Saturday, and that the conversation, as indicated above, took place between him and Ross. Halliwell signed a statement and left. There is little doubt that statement contains the assertion that Halliwell was at the saloon on the Thursday.
