Part 2 (1/2)

”They have,” a.s.sented he, with obvious satisfaction. ”I sent a copy of the story to my Chief--just to put myself straight with him. I said that it was all quite unauthorised, and that I would have stopped it if I could.”

”Oh no, you wouldn't. Don't talk humbug, Mr. William Dawson. During the past two months you have pranced along the streets with your head in the clouds. And in your own home Mrs. Dawson and the little Dawsons--if there are any--have wors.h.i.+pped you as a G.o.d. There is nothing so flattering as the sight of oneself in solid black print upon nice white paper. Confess, now. Are you not at this moment carrying a copy of that story of mine in your breast pocket next your heart, and don't you flourish it before your colleagues and rivals about six times, a day?”

Alone among mortal men I have seen a hardened detective blush.

”Throw away that cigarette,” said I, ”and take a cigar.” I felt generous.

Our relations were now established upon a basis satisfactory to me. I had no inkling of the purpose of this visit, but he had lost the advantage of mysterious attack. He had revealed human weakness and had ceased for the moment to dominate me as a terrible engine of the law.

But I had heard too much of Dawson from Cary to be under any illusion.

He could be chaffed, even made ridiculous, without much difficulty, but no one, however adroit, could divert him by an inch from his professional purpose. He could joke with a victim and drink his health and then walk him off, arm in arm, to the gallows.

”Now, Mr. Dawson,” said I. ”Perhaps you will tell me to what happy circ.u.mstance I owe the honour of this visit?”

He had been chuckling over certain rich details in the Hagan chase--with an eye, no doubt, to future enlarged editions--but these words of mine pulled him up short. Instantly he became grave, drew some papers from his pocket, and addressed himself to business.

”I have come to you, Mr. Copplestone, as I did to your friend Mr.

Cary, for information and a.s.sistance, and I have been advised by those who know you here to be perfectly frank. You are not at present an object of suspicion to the local police, who a.s.sure me, that though you are known to have access to much secret information, yet that you have never made any wrongful use of it. You have, moreover, been of great a.s.sistance on many occasions both to the military and naval authorities. Therefore, though my instinct would be to lock you up most securely, I am told that I mustn't do it.”

”You are very frank,” said I. ”But I bear no malice. Ask me what you please, and I will do my best to answer fully.”

”I ought to warn you,” said he, with obvious reluctance, ”that anything which you say may, at some future time, be used in evidence against you.”

”I will take the risk, Mr. Dawson,” cried I, laughing. ”You have done your duty in warning me, and you are so plainly hopeful that I shall incriminate myself that it would be cruel to disappoint you. Let us get on with the inquisition.”

”You are aware, Mr. Copplestone, that a most important part of my work consists in stopping the channels through which information of what is going on in our s.h.i.+pyards and munition shops may get through to the enemy. We can't prevent his agents from getting information--that is always possible to those with unlimited command of money, for there are always swine among workmen, and among higher folk than workmen, who can be bought. You may take it as certain that little of importance is done or projected in this country of which enemy agents do not know. But their difficulty is to get it through to their paymasters, within the limit of time during which the information is useful. There are scores of possible channels, and it is up to us to watch them all. You have already shown some grasp of our methods, which in a sentence may be described as unsleeping vigilance. Once we know the ident.i.ty of an enemy agent, he ceases to be of any use to the enemy, but becomes of the greatest value to us. Our motto is: Ab hoste doceri.” He p.r.o.nounced the infinitive verb as if it rhymed with glossary.

”You are quite a scholar, Mr. Dawson,” remarked I politely.

”Yes,” said he, simply. ”I had a good schooling. I need not go into details,” he went on, ”of how we watch the correspondence of suspected persons, but you may be interested to learn that during the three weeks which I have pa.s.sed in your city all your private letters have been through my hands.”

”The devil they have,” I cried angrily. ”You exceed your powers. This is really intolerable.”

”Oh, you need not worry,” replied Dawson serenely. ”Your letters were quite innocent. I am gratified to learn that your two sons in the Service are happy and doing well, and that you contemplate the publication of another book.”

It was impossible not to laugh at the man's effrontery, though I felt exasperated at his inquisitiveness. After all, there are things in private letters which one does not wish a stranger, and a police officer, to read.

”And how long is this outrage to continue?” I asked crossly.

”That depends upon you. As soon as I am satisfied that you are as trustworthy as the local police and other authorities believe you to be, your correspondence will pa.s.s untouched. It is of no use for you to fume or try to kick up a fuss in London. Scotland Yard would open the Home Secretary's letters if it had any cause to feel doubtful of him.”

”You cannot feel much suspicion of me or you would not tell me what you have been doing.”

”You might have thought of that at once,” said Dawson derisively.

I shook myself and conceded the round to Dawson.

”It has been plain to us for a long time that the food parcels despatched by relatives and 'G.o.d-mothers' of British prisoners in Germany were a possible source of danger, and at last it has been decided to stop them and to keep the despatch of food in the hands of official organisations. Since there are now some 30,000 of military prisoners, in addition to interned civilians at Ruhleben, the number and complexity of the parcels have made it most difficult for a thorough examination to be kept up. We have done our utmost, but have been conscious that there has existed in them a channel through which have pa.s.sed communications from enemy agents to enemy employers.”
