Mr. Blair she hated the sight of, he was so obviously satisfied with the course of events. Sometimes she found herself longing for the return of John Dene, merely that he might "ginger-up" Sir Lyster's private secretary. Week after week passed and no news. The volume of questions in the House died down and finally disappeared altogether. The state of affairs at Scotland Yard returned to the normal. Newspapers ceased to refer either to John Dene, or to his disappearance, and the tide of war flowed on. Marshal Foch had struck his great blow, and had followed it up with others. The stream of Hun invasion had been stemmed, and slowly France and Belgium were being cleared. Mr. Montagu Naylor's comings and goings continued to interest Department Z., and Apthorpe Road was still in the grip of the workman. Day by day Dorothy seemed to grow more listless. It was the heat, she explained to Mrs. West, whilst Marjorie nodded her wise little head, but said nothing. Whenever she saw Dorothy she always "talked John Dene," as she expressed it to herself. She could see that it was a relief. "You see, Rojjie darling, I should always be a little afraid of him," said Dorothy one day as they sat in John Dene's room. "I suppose that is why I----" She paused. Marjorie nodded understandingly, and continued to swing a dainty, grey-stockinged leg. "You--you see," continued Dorothy a little wistfully, "I've always had to do the taking care of, and he----" Again she broke off. Then suddenly jumping up she cried, "Let's go to the pictures. Bother John Dene!" and Marjorie smiled a little smile that was really her own. Finally there came the time when for a fortnight Dorothy would have no one to say to her either "come" or "go," and she and Mrs. West went to Bournemouth, Dorothy inwardly dreading two weeks with nothing to do. II Whilst the John Dene sensation was slowly fading from the public mind, Malcolm Sage was continuing with unabated energy the task he had set himself. He was aware that Finlay was being watched even more closely than John Dene had been watched, and Sage realised that it was, in all probability, impossible for him to communicate with headquarters. By an ingenious device, however, Finlay had at length succeeded in establishing contact with Department Z. It had been reported to Sage that on two occasions Finlay had been seen to leave behind him at restaurants a silver-mounted ebony walking stick. He had, however, always returned for it a few minutes later, as if having discovered his loss. Learning that the stick was of an ordinary stock pattern, Malcolm Sage gave instructions for one exactly like it to be purchased. An endeavour was then to be made to effect an exchange with that carried by Finlay. It was not until a week later that this was effected, and the stick handed to Thompson.
