They knew each other well, these two men, and had been brought together several times on affairs of public importance. Before he had thrown all his energies into politics Mr Carlingford had been one of the most successful barristers of the day. His intellect was of the keen and subtle order. He was, of course, profoundly interested in the mysterious disappearance of his colleague, the Colonial Secretary, and had sent for the detective to talk over the matter. "Sit down, Smeaton. Have you any news? I know you are not a man to let the grass grow under your feet." Smeaton explained the situation as it stood at present. "We have partly identified one, and in my opinion the more important, of the two men who put him in the taxi. His name is given to me as Stent, and he is supposed to have a house somewhere in the neighbourhood of St Albans. One of my best sergeants is down there to-day, making inquiries. I fancy we are also on the track of the second man." He added that it was to Farloe's sister, Mrs Saxton, that he was indebted for the somewhat scanty information he possessed. "I met that lady last winter at Mentone," remarked the Home Secretary. "She was an attractive young woman, with ingratiating manners. I remember she introduced herself to me, telling me that her brother was Monkton's secretary. My impression at the time, although I don't know that I had any particular evidence to go on, was that there was just a little touch of the adventuress about her." "Precisely my impression," agreed the man from "over the way." "I never took to that fellow, Farloe, either," continued the statesman. "I don't think Monkton was particularly attached to him, although he admitted he was the best secretary he ever had. I always thought there was something shifty and underhand about him." They talked for a few moments longer, exchanging probable and possible theories, and then Smeaton rose to take his leave. "Well, Mr Carlingford, thanks to your kind help we have been able to keep it out of the Press so far. I hope our inquiries will soon bear some fruit," he said, and then left the room. Sheila had gone home feeling very sad and lonely. All her plans for the day had been upset by Wingate's sudden journey to Brighton. She had looked forward to spending some hours in the society of her lover. The excitement of the detective business in which they proposed to engage for the rest of the day would have taken her out of herself, and kept alive the courage which flagged sorely now and again, as she confronted the apparently insoluble problem of her beloved father's disappearance. Her luncheon finished, she went into her own dainty little sitting-room and tried to read. But she could not focus her attention. Her thoughts strayed away from the printed page, and at last she flung down the book impatiently.
