The Lost Naval Papers Part 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."

"I can see the possibility, but a practical method of communication looks difficult. How was it done?"

"In the most absurdly simple way. Real ingenuity is always simple. I will give you an example. An English prisoner in Germany has, we will suppose, parents in Newcastle, by whom food has been sent out regularly. He dies in captivity, and in due course his relatives are notified through the International Headquarters of the Red Cross in Geneva. He is crossed off the Newcastle lists, and his parents, of course, stop sending parcels. Now suppose that some one in Birmingham begins to send parcels addressed to this lately deceased prisoner, his name, unless Birmingham is very vigilant, will get upon the lists there as that of a new live prisoner. The parcels addressed to this name will go straight into the hands of the German Secret Service, and a channel of communication will have been opened up between some one in Birmingham and the enemy in Germany. Prisoners are frequently dying, new prisoners are frequently being taken. Under a haphazard system of individual parcels, despatched from all over the British Isles, it has been practically impossible to keep track of all the changes. For this, and other good reasons, we have had to make a clean sweep and to take over the feeding of British prisoners by means of a regular organisation which can ensure that nothing is sent with the food which will be of any a.s.sistance to the enemy."

"That is a good job done," I observed. "Have you evidence that what is possible has in fact been done?"

"We have," said Dawson. "Not many cases, perhaps, but sufficient to show the existence of a very real danger. It is, indeed, one particular instance of direct communication which has brought me to you to-day. Orders were given not long since that all new cases, that is, all parcels addressed to prisoners whose names were new to local lists, should be opened and carefully examined. Some six or seven weeks ago parcels began to be sent from this city addressed to a lieutenant in the Northumberland Fusiliers. There was nothing remarkable in that, for though we are some distance here from Northumberland, young officers are gazetted to regiments which need them irrespective of the part of the country to which the officers themselves belong. In accordance with the new orders all the parcels for this lieutenant--which usually consisted of bread, chocolate, and tins of sardines--were examined. The bread was cut up, the chocolate broken to pieces, and the tins opened. If the parcel contained nothing contraband, fresh supplies of bread, chocolate and sardines to take the place of those destroyed in examination were put in, and the parcel forwarded. For the first two weeks nothing was found, but in the third parcel, buried in one of the loaves, was discovered a cutting from an evening newspaper which at first sight seemed quite innocent. But a microscopic search revealed tiny needle p.r.i.c.ks in certain words, and the words, thus indicated, read when taken by themselves the sentence, 'Important naval news follows.' At this stage I was sent for. My first step was to inquire very closely into the antecedents of this lieutenant of Northumberland Fusiliers. I found that his friends lived at Morpeth, that he had been taken prisoner during the Loos advance of September 1915, and that he had died about a year later of typhoid fever in a German camp. His friends, as soon as they had been informed, of the death, had stopped sending parcels of food out to him. They were not told the object of the inquiries. It would have caused them needless pain. It was bad enough that their only son had died far from home in a filthy German prison."

Dawson's rather metallic voice became almost sympathetic, and I was pleased to observe that his harsh profession had not destroyed in him all human feeling.

"After this you may suppose that the parcels addressed to our poor friend the late lieutenant were very eagerly looked for. The alleged sender, whose name and residence were written upon the labels, was found not to exist. Both name and address were false. It was a hot scent, and I was delighted, after a week of waiting, to see another parcel come in. This would, in all probability, contain the 'important naval news,' and I took its examination upon myself. I reduced the bread and the chocolate to powder without finding anything."

"Excuse me," I cried, intensely interested, "but how could one conceal a paper in bread or in chocolate without leaving external traces?"

"There is no difficulty. The loaves were of the kind which have soft ends. One cuts a deep slit, inserts the paper, closes up the cut with a little fresh dough, and rebakes the loaf for a short time, till all signs of the cut have disappeared. The chocolate was in eggs, not in bars. The oval lumps can be cut open, scooped out, a paper put in, and the two halves joined up and the cut concealed by means of a strong mixture of chocolate paste and white of egg. When thoroughly dried in a warm place, chocolate thus treated will stand very close scrutiny. I did not trouble to look for signs of disturbance in either loaves or eggs; it was quicker and easier to break them up. I then addressed my attention to the sardine tins, which from the first had seemed the most likely hiding-places. A very moderately skilled mechanic can unsolder a tin, empty out the fish and oil, put in what he pleases in place, weight judiciously, and then refasten with fresh solder. I opened all the tins, found that all except one had been undisturbed, but that one was a blissful reward for all my trouble, for in it was a tightly packed ma.s.s of glazier's putty, soft and heavy, and at the bottom the carefully folded paper which I have now the honour of showing to you."

Dawson handed me a stiff piece of paper, slimy to the touch and smelling strongly of white lead. Upon it were two neatly made drawings and some lines of words and figures. "It is just what I should have expected," said I.

"You recognise it?"

"Of course," said I. "We have here a deck plan showing the disposition of guns, and a section plan showing arrangement of armour, of one of the big new s.h.i.+ps which has been completed for the Grand Fleet. Below we have the number and calibre of the guns, the thickness and extent of the armour, the length, breadth, and depth of the vessel, her tonnage, her horse power, and her estimated speed. Everything is correct except the speed, which I happen to know is considerably greater than the figure set down."

"You have not by any chance seen that paper before?" asked Dawson, with rather a forced air of indifference.

"This? No. Why?"

"I was curious, that's all." He looked at me with a queer, quizzical expression, and then laughed softly. "You will understand my question directly, but for the moment let us get on. What sort of person should you say made those drawings and wrote that description?"

I am no Sherlock Holmes; but any one who has had some acquaintance with engineers and their handiwork can recognise the professional touch.

"These drawings are the work of a trained draughtsman, and the writing is that of a draughtsman. One can tell by the neatness and the technique of the shading."

"Right first time," said Dawson approvingly. "At present I have that draughtsman comfortably locked up; we picked him out of the drawing office at ----" he named a famous yard in which had been built one of the s.h.i.+ps of the cla.s.s ill.u.s.trated upon the paper in my hands.

"Poor devil," I said. "What is the cause--drink, women, or the pressure of high prices and a large family?"

"None of them. His employers give him the best of characters, he gets good pay, is a man over military age, and has, so far as the police can learn, no special embarra.s.sments. He owns his house, and has two or three hundred pounds in the War Loan."

"Then why in the name of wonder has the _schweinehund_ sold his country?"

"He declares that he never received a penny for supplying the information upon that paper, and we have no evidence of any outside payments to him. He did not attempt to conceal his handwriting, and when I made inquiries of his firm, he owned up at once that the paper was his work. He said that for years past he had given particulars of s.h.i.+ps under construction to the same parties as on this occasion. He admitted that to do so was contrary to regulations, especially in wartime, but thought that under the circ.u.mstances he was doing no harm. I am not exactly a credulous person, and I have heard some tall stories in my time, but for once I am inclined to believe that the man is speaking the truth. I believe that he received no money, and was acting throughout in good faith."

"I am more and more puzzled. What in the world can the circ.u.mstances be which could induce an experienced middle-aged man, employed in highly confidential work in a great s.h.i.+pyard, not only to break faith and lose his job, but to stick his neck into a rope and his feet on the drop of a gallows. Reveal the mystery."

"You are sure that you have never seen that paper before?" asked Dawson again, this time slowly and deliberately.

"Of course not!" I said. "How could I?"

"That is just what I have to find out," said Dawson. He stopped, took out a knife, prodded his nearly smoked cigar, puffed once or twice hard to restore the draught, and spoke. "That is what interests me just now. For, you see, this very indiscreet and reprehensible swinehound of a draughtsman, who is at present in my lockup, declares that he was without suspicion of serious wrong-doing, because --because--the particulars of the new battles.h.i.+p upon that paper were supplied to YOU."
