made the nucleus of his present fortune." "That's all news to me," said Jack reflectively; "and yet--" "What? Do you know something regarding Rodwell then?" inquired Sir Houston quickly. "No," he replied. "Nothing very extraordinary. What you have just told me surprises me greatly." "Just as it surprised me. Yet, surely, his case is only one of many similar. Thousands of Germans have come here and become naturalized Englishmen." "A German who becomes a naturalized Englishman is a traitor to his own country, while he poses as our friend. I contend that we have no use for traitors of any sort in England today," declared Jack vehemently; both men being still engaged in searching the dead man's room to discover the message which it appeared had been his intention to leave after his death. They had carefully examined the grate, but found no trace of any burnt paper. Yet, from the fact that a piece of red sealing-wax and a burnt taper lay upon the writing-table, it appeared that something had been recently sealed, though the torn envelope bore no seal. If an envelope had been sealed, then where was it? "We shall, no doubt, be able to establish the truth of Jerrold's allegation by reference to the register of naturalized Germans kept at the Home Office," Sir Houston said at last. Jack was silent for a few moments, and then answered: "That, I fear, may be a little difficult.

As an example, if Ludwig Heitzman became naturalized, then it is more than probable that when he changed his name by deed-poll he did not adopt the name of Lewin Rodwell, but something rather near it." "Very likely," was the great doctor's remark. Suddenly Jack Sainsbury paused and, facing his companion, said: "Look here, Sir Houston. In this tragic affair, I believe there's something more than suicide. That's my firm opinion. Reflect for one moment and follow my suspicions. Poor Jerome, in addition to his profession, has for some years been unofficially assisting the Intelligence Department of the War Office. He was one of the keenest and cleverest investigators in England. He scented acts
