"Mr. Marwood rang up Scotland Yard at half-past ten last night. He told them he had received an anonymous letter giving two addresses, at one of which you would probably be found. He also gave a full description of the alterations in your appearance." I turned to Latimer. "I suppose it was Sonia," I said. "I never dreamed of her going to him, though." "It was very natural," he replied in that unconcerned drawl of his. "She knew that your cousin would do everything possible to get you under lock and key again, and at the same time she imagined she would avoid the risk of being arrested herself." "Quite so, quite so," said Sir George, nodding his head sagely. "From all I can gather she seems to be a most dangerous young woman. I shall make a particular point of seeing that she is arrested." His words came home to me with a sudden swift stab of pity and remorse. It was horrible to think of Sonia in jail--Sonia eating out her wild passionate heart in the hideous slavery I knew so well. The thought of all that she had risked and suffered for my sake crowded back into my mind with overwhelming force. I took a step forward. "Sir George," I said, "a moment ago you were good enough to say that the Government would try and make me some return for the injustice I have suffered." He looked at me in obvious surprise. "Certainly," he said--"certainly. I am convinced that they will take the most generous view of the circumstances." "There is only one thing I ask," I said. "Except for this girl, Sonia Savaroff, the Germans would now be in possession of my invention. If the Government feel that they owe me anything, they can cancel the debt altogether by allowing her to go free." Sir George raised his eyeglass. "You ask this after she did her best to send you back to penal servitude?" I nodded. "I am not sure," I said, "that I didn't thoroughly deserve it." For a moment Sir George stared at me in a puzzled sort of fashion. "Very well," he said; "I think it might be arranged. As you say, she was of considerable assistance to us, even if it was unintentionally. That is a point in her favour--a distinct point." "How about our friend Mr. Marwood?" put in Lammersfield pleasantly. "Between perjury and selling Government secrets I suppose we have enough evidence to justify his arrest?" "I think so," said Sir George, nodding his head solemnly. "Anyhow I have given instructions for it. In a case like this it is best to be on the safe side." My heart sank at his words. Charming as it was to think of George in the affectionate clutch of a policeman, I could almost have wept at the idea of being robbed of my own little interview with him, to which I had been looking forward for so long. It was Lammersfield who broke in on my disappointment. "I should imagine," he said considerately, "that you two, as well as Latimer, must be half starving. I suppose you have had nothing to eat since breakfast."
