The Chief Commissioner was particularly annoyed because all his own correspondence had been engulphed in the epistolary flood, and he was expecting a letter from his wife telling him where to meet her on the following day on her return from a motor tour. Those who knew Lady Wrayle understood the Chief Commissioner's anxiety.

All day long Scotland Yard worked in a conscientious endeavour to sift the ma.s.s of evidence that streamed in upon it from all parts of the kingdom. Some of the stories to which weary but patient officials listened were grotesque in the extreme. As the chief expressed it, "Half the idiots and all the d.a.m.ned fools in the country are descending upon us."

The callers were interesting as studies in obtuseness and optimism; but they were as nothing to the telegrams. One man wired from St. Andrews that he was tracking a strange man round the golf course, would Scotland Yard telegraph a warrant for his arrest? Another enquired if the reward would be in cash or war bonds, and if the Government guaranteed the money--this man telegraphed from Aberdeen. Several asked for railway warrants to London that they might lay certain facts before the authorities. Scores telegraphed for photographs, as the pictures in the papers were indistinct. One lady telegraphed from Suffolk that a man with a beard identical with that worn by John Dene in the picture in _The Daily Photo_ had that day come to her door begging.

The telegrams were, however, nothing to the letters that followed them.

The lady who had telegraphed about a bearded John Dene, wrote to apologise for her mistake, explaining it by saying that the paper boy must have accidentally rubbed the paper before delivering it. She was not to be denied, however, and went on to say that she thought the picture strangely like the man who had begged of her. Did Scotland Yard think that John Dene had disguised himself with a false beard?

Some correspondents wrote bitterly censuring the Government for not interning all aliens, for allowing John Dene out of its sight, for an Imperialistic policy, for plunging the country into war, for offering the reward, and for a thousand and one other irrelevant things. The one thing that no one did was to supply any information that would be remotely useful to the authorities in tracing the missing man.

People waited eagerly for the morrow's papers. They contained another surprise, this time in the form of a two column advertis.e.m.e.nt, offering 20,000 for information that would lead to the discovery of the whereabouts of John Dene. Clearly somebody was determined that John Dene should be found.

When Mr. Llewellyn John opened the first morning paper he picked up from the pile awaiting him he gasped. Himself a great believer in the possibilities of the press, he felt, nevertheless, that Department Z.

was overdoing things, and he telephoned for its chief and Malcolm Sage to call upon him at ten o'clock.

At two minutes to ten, the two presented themselves at No. 110, Downing Street, and were immediately shown into the presence of the Prime Minister.

"Has it struck you," asked Mr. Llewellyn John, indicating one of the advertis.e.m.e.nts, "that questions will be asked in the House as to whether or no the Government is offering these large rewards?"

"I should think it highly probable, sir," was Sage's response.

"And what are we to say?" demanded Mr. Llewellyn John. He was a keen politician, and saw that the situation might be fraught with considerable difficulties.

"Acknowledge that they are, sir," was the response.

"Acknowledge it!" cried Mr. Llewellyn John.

"Certainly, sir."

"Mr. Sage," said Mr. Llewellyn John severely, "you do not appear to appreciate that this may seriously compromise the Government." Then turning to Colonel Walton he continued: "Hitherto you have been given a free hand, now I must ask you to explain why you are offering these large rewards. You first of all suggested 1,000, rising daily from 1,000 to 10,000. In two days it has amounted to 20,000."

"It won't rise any higher, sir. It has reached the limit."

"That is not the point," said Mr. Llewellyn John. "I want to know why it is that you are advertising to Germany that we want John Dene. It is an obvious confession of weakness." He made a quick nervous movement with his right hand, he was far from easy in his mind.

Malcolm Sage continued to examine his finger-nails with great intentness.

Seeing that he made no indication of replying, Mr. Llewellyn John continued:

"I'm afraid that this cannot go on." There was a suggestion of irritability in his voice.

"Then have it stopped, sir," said Sage calmly, still intent upon the finger-nails of his right hand.

"The mischief is done," said Mr. Llewellyn John. "What is at the back of your mind, Sage?" he demanded.

"I'm working on a hypothesis, sir," was the reply. "I think I'm right, in fact I'm convinced of it; but until I know for certain, I must keep my theories to myself. If you wish it, I'll tell you what I actually know; but I make it a rule never to air theories."

Mr. Llewellyn John smiled. "Well, tell me what you actually know then," he said.

"When Mr. Dene left his office at three minutes past six on Monday evening, he stood for nearly a minute, as if making up his mind in what direction to go. Just as he was about to turn and walk up Regent Street a taxi crawled past him. The driver spoke to him and John Dene got in and drove away."

"Kidnapped!" exclaimed Mr. Llewellyn John.

Malcolm Sage shrugged his shoulders.

"In which direction did he drive?" enquired Mr. Llewellyn John eagerly.

"Along Pall Mall, sir," was the reply. "Colonel Walton told you what happened?"

Mr. Llewellyn John nodded. "And have you informed the police?" he asked.

Malcolm Sage shook his head.

"Why?" enquired Mr. Llewellyn John eagerly.

"If my theory is right," said Sage, "it's unnecessary. If my theory's wrong, it's useless. Believe me, sir, our best course is to continue to boom John Dene's disappearance for all we are worth."

"But the _Destroyer_!" exclaimed Mr. Llewellyn John excitedly.

"You know the conditions, sir, that the island of Auchinlech was to be left severely alone for four months."

"Do you imagine that Dene slipped off to the north to trick the Germans?"

"That wouldn't trick them, sir," said Malcolm Sage quietly. "John Dene would never have been allowed to reach Auchinlech alive. That was settled. I may add that I have every reason to believe that the taxi and its occupant did not go fifty miles from London."

"And that he is a prisoner?" Mr. Llewellyn John jumped from his chair.

Malcolm Sage inclined his head in the affirmative.

"Good heavens!" exclaimed Mr. Llewellyn John, "we must----"

"Depend entirely upon the advertis.e.m.e.nts," said Sage, rising. "You will of course regard this as strictly confidential, and to be told to no one. I cannot tell you how important it is." There was an unaccustomed note of seriousness in Sage's voice, which did not fail to impress Mr. Llewellyn John.

"But the questions in the House as to why we are offering this reward?"

persisted Mr. Llewellyn John. "What reply are we to make?"

"You might fall back on the old cliche, sir: 'Wait and see.'"

Mr. Llewellyn John smiled.

"That phrase," continued Sage, "was a great a.s.set to one party, why should it not be to another?"

"Look at this." Mr. Llewellyn John held out a slip of paper, which Colonel Walton took and read aloud.

"Has the attention of the Home Secretary been drawn to a statement in _The Tribune_ to the effect that it is the Government that is offering the reward of 10,000 for information that will lead to the discovery of the whereabouts of Mr. John Dene of Toronto, and if so can it justify the offer of so large a sum of public money?"

"They haven't lost any time," remarked Sage quietly.
