Not being in a position to raise a question I let it go at that, never for a moment thinking that my employers would be so culpably careless as to put any incriminating evidence in the mail. Events proved that that is just what they did. Moreover, I later came to know why that particular letter was addressed not to James but to A. Stafford. All my previous letters were addressed to me as Dr. A. K. Graves and were enclosed in the business envelope of the well-known chemical firm of Burroughs & Wellcome, Snowhills, London, E. C.--which paper had been fabricated for the purpose. Of course the letters were sent from the Continent to London and there reposted. The stationery of this chemical firm was fabricated so as to disarm any possible suspicion, for European post-offices are taught to be suspicious. It would be perfectly natural for me, a physician in Edinburgh, to receive a letter from a very well-known chemical concern.

When I left Edinburgh to find out about the fourteen-inch guns, I gave our people in London instructions to use plain envelopes and to address them to James Stafford, G. P. O., Glasgow. The first two letters were addressed correctly and plain envelopes were used. _The third was not only misaddressed but was enclosed in one of the B. & W. envelopes_--this as I later learned, for a reason.

No one having called for it, the letter was returned to the chemical company. At their office it was opened and found to contain a typewritten letter in the German language and five ten-pound notes on the Bank of England. The contents of the letter, was such as to lead the firm to call in the police.

On the evening of April 10, I had just put on my evening clothes and gone to the upstairs writing-room. I was awaiting a party of gentlemen who were coming to dine with me in the hotel. There came a "b.u.t.tons" who announced:

"There's a gentleman downstairs to see you, Doctor."

A premonition stole over me. I knew that my guests would not have sent for me to come down but would have been announced. I realized that if I was going to be caught there was no avoiding it. Secret Service makes a man a fatalist. I took the precaution, however, to slip inside my dinner coat just under the arm, my little bag of chemicals, so often handy in an emergency. Then I went downstairs, one hand was thrust in my pocket, the other folded across my breast so that I could s.n.a.t.c.h the little bag of chemicals in an emergency.

I had hardly reached the last step of the grand stairway when four big plain-clothes men, pounced upon me. I had to do some swift thinking.

I could have flung the chemicals in their faces and escaped, but I knew I could never get outside of the British Isles without being caught--outside of Glasgow for that matter. Such resistance would only incriminate matters still more, so I let my hand fall down to my side. More for the fun of it than anything else, I guess, I got on my horse and demanded to know what was the matter.

"You'll soon know," Inspector French declared.

It seems that a woman had just called me on the telephone and the Inspector, hurrying to the wire, pretended that he was I and tried to learn something.

He then ordered his men to search me and seemed amazed when they couldn't find any six shooters, daggers or bombs. I was taken back to my room and there he began going through my effects, and bundling them up. I knew I was up against it; but I wasn't going to make it any easier for them. I requested Mr. Morris, then manager of the hotel, and another witness to be called into my room. These gentlemen were kind enough to put down on paper a description of all my effects that were being taken away by the police. I was extremely careful to see that they noted and described all papers and written matters of any kind. There are often produced in court doc.u.ments that are not found on a Secret Service agent at the time of his arrest. Inspector French--I recall him as an uncouth, illiterate bungler who subsequently tried to get a lot of publicity out of my arrest as if he himself had detected the whole concern, instead of having it thrust under his nose by the London chemical company--was preparing to ride over me roughshod. I insisted that he read the warrant for my arrest and with much grumbling he finally did so. It had been issued under the Official Secret Act that had been rushed through the House of Commons. I was charged with endangering the safeguards of the British Empire.

I spent the night in the Glasgow City Prison, and was taken the next day before a magistrate and formally committed to a sheriff's court.

On July 12 my case came up before the Sheriff's court. Waiving preliminary examination, I was committed for trial to the Edinburgh High Court. It is significant that the extreme length of a committal without trial under British law is one hundred and five calendar days, which hundred and five days up to the last minute I certainly waited.

They were trying to find out my antecedents but they did not succeed.

A letter from the Lord Provost informed me that all material for my defense should be in his hands a day before the trial. I had no defense. I neither denied nor admitted anything. I replied to his Lordship that as I was unaware of any offense there was no need of any defense. My att.i.tude was a profound puzzle--which was as I wanted.

If you care to look over the back files of the English and Scottish newspapers of the time you will read that my trial was "the most sensational court procedure ever held in a Scottish court of justice."

Now I shall reveal every circ.u.mstance of it. For the first time I shall explain how, why and by whom I was secretly released. Until I revealed myself in the United States, even the German Foreign Office thought me in jail.

Against me the crown had summoned forty-five witnesses. They included admirals, colonels, captains, military and naval experts, post office officials--I cannot recall all. The press from all parts of Europe--for all Europe was vitally concerned in this trial--was represented. My memory shows me again the crowds that packed the big supreme court building at Edinburgh on the first day of the proceedings. The imposing names connected with the trial, the strange circ.u.mstances, a spy, moreover a German!--These things brought the excitement to fever heat.

Presiding was the Lord Justice of Scotland, himself no mean expert in military matters. The Solicitor General of Scotland, A. M. Anderson, who prosecuted for the crown, was supported by G. Morton, Advocate Deputy. The government had indeed an imposing array of bewigged, black-gowned, legal notables marshaled against me.

Those familiar with English court procedure know the impressive manner with which justice is dispensed. Punctually at ten on the morning of July 22, 1912, my trial opened. Clad in his royal red robe with the ermine collar of supreme justice, the Lord Justice entered the court.

Before him walked a mace bearer, intoning "Gentlemen, the Lord Justice! Gentlemen, the Court!" After the impressive ceremonies had been observed, the jury was quickly empaneled, I making several challenges. Twelve years in the Secret Service naturally has made me know something of men. I knew that those twelve hard-headed, cautious Scottish jurymen would demand pretty substantial proof before convicting. At the time I am frank to say that I did not think there was a chance of a verdict of guilty being brought in. The evidence against me was too vague.

Expressing astonishment at my refusal to accept counsel--which was subsequently forced on me--His Lordship promised to guard my interest on legal points; and guard it he did. Repeatedly he ruled against the Solicitor General and challenged him on more than one point. I am frank in my admiration of British justice. My trial was a model of fairness.

On the first day I waived examination on all witnesses but the naval and military experts. I directed my fire against Rear Admiral T. B. Stratton Adair, who superintended the ordnance factories of the Beardmore Gun Works in Glasglow. The Admiral a typical English gentleman of the naval officer type, long, lank with a rather ascetic, clear-cut Roman head, not unlike Chamberlain in general appearance, even to the single eye-gla.s.s, did not make much of a showing as an expert witness for the prosecution. The Admiral was called in on testimony concerning the new fourteen-inch gun. The point they were trying to establish was that it was impossible for a man to have my knowledge of these guns unless he had obtained it first hand from the works in Glasgow. Of course that brought the testimony into technicalities. I managed to involve the Admiral in a heated altercation on the trajectory and penetrating power of the so-much disputed fourteen-inch gun. One word led to another and notwithstanding that he ranked at that time as a rear admiral of the British Navy, the Admiral showed that he did not know as much about his own guns as I. Backed into this corner he was about to divulge things in support of his knowledge when he recovered himself, pulled up suddenly and appealed to the Court.

"Your Lordship, it is against the British Government to have any more questions on this point in open court."

I maintained that my knowledge of guns was such that I did not need to spy at Beardmore to obtain the things I knew. Subsequently after being cross-examined by me another of the government's naval experts told the court:

"It is quite possible for one with a ballistic knowledge such as the defendant's to be able with very little data to arrive at accurate conclusions regarding our new fourteen-inch guns."

_A word of advice to the Admiral._ Do not talk so much when you go motor boating with pretty young musical comedy girls. You see, Admiral, I made it my business to see those young ladies in Glasgow.

What an interest they took in you--a great Admiral! It is you, Admiral, whom I thank for aiding me in securing the right persons from whom the secrets of your new fourteen-inch guns could be obtained.

A note they found in my effects was introduced as evidence. It read as follows:

"The firm of William Beardmore and Co., Parkhead, Glasgow. B first orders F new 13.5 guns F, Navy. Length 51 feet, weight 73 tons. One foot longer than 12-inch, but 12 tons heavier. Weight of shot, 1,250 lb., 400 lb. more than the 12-inch gun."

The upshot of it was that the first day of the trial ended with everybody positive that I would not be found guilty on the charge of obtaining secret information about their guns. Of course all this information I had obtained.

On the recess I was pleasantly surprised when a court orderly brought me refreshments from the judge's own table with his Lordship's compliments. It struck me that I was being treated more like a guest than a prisoner.

The second day of the trial brought the Burroughs & Wellcome letter into the testimony--the letter that had been refused me and had in turn gone back to the Chemical Company. Very gravely Sir Anderson, Crown Prosecutor, read the contents of this letter aloud. As I recall the exact wording it was:

_Dear Sir:_

_We are pleased to learn of your successful negotiation of the business at hand. Be pleased to send us an early sample. As regards the other matter in hand I do not know how useful it will be to us: In any case my firm is not willing to pay you more than 100 in this case._

It was unsigned.

While reading, Sir Anderson held the five ten-pound notes in his hand.

Upon finishing he began a vigorous indictment which in substance he declaimed in this way.

"On the face of it, this letter does not seem suspicious. But if you gentlemen will recall the times of Prince Charles' insurrections, periods whenever intrigues were going on, you will remember that in communications of this sort a government was always referred to as a 'firm.' If this was an honest business letter why was it enclosed in the envelope stationery of a company that knew nothing about it? Why was this letter unsigned? Why was cash enclosed, with it? What was his firm willing to pay 100 pounds for? Gentlemen, the reasons for all these things are obvious."

But the letter puzzled not only the court, the jury, the newspapers, but all England. For the first time I shall now explain it:

It was from the German government. By the "business at hand" they meant a new explosive and slow-burning powder that was to be used in the new type of fourteen-inch turret guns being made in Glasgow. Some of that explosive was in my possession. The fact that it was not discovered in my effects, nor was anything else incriminating found on me is because the Secret Agent who knows his business leaves nothing about; but he "plants" things, that is to say, leaves them in a safe deposit vault with the key in the hands of a person with power of attorney.

By the "sample" in the letter was meant a sample of the explosive.

The "other business at hand" was spoken of as of tremendous importance, more vital to the safeguards of Britain than the other points mentioned in the letter.

There were sub-agents working at Cromarty. I did not know who they were; they simply made their reports to me, signing their German Secret Service number. I took up their points with Berlin. Well, the "other business in hand" was to put a certain British army officer under a monthly retaining fee of 100 for which in the event of war he was to commit an act of unspeakable treason and treachery on a certain harbor defense.

I had judged my jurymen right, for they were very little impressed by this letter. It was all too vague and even the fluent language of a Crown Prosecutor does not impress a hard-headed Scotchman. I was feeling in high spirits indeed, when I saw one of the attendants approach Sir Anderson and deliver a doc.u.ment that had been handed into court. I at once recognized it and my heart dropped into my shoes.

The Solicitor General read the doc.u.ment and smiled. I knew they had me.

In addressing the court the Solicitor General produced two pieces of thin paper--the same that had been brought in on the previous afternoon.

"I have got to show the court," he said impressively, "the most deadly code ever prepared against the safeguards of Great Britain."

And it certainly was. It contained the name of every vessel in the British Navy, every naval base, fortification and strategic point, in Great Britain. There were over ten thousand names and opposite each was written a number. For example, the battle cruiser _Queen Mary_ was number 813.

As I have confessed, I am superst.i.tious. And have I not reason to be?

It was the Burroughs & Wellcome letter that got me caught in the first place. And my secret code was written in a book issued for the use of physicians by Burroughs & Wellcome! Both times the B & W mark was upon me.

Using a magnifying gla.s.s I had written in tiny characters my code.

There were so many names it was impossible to memorize them all. Two opposite sheets of the little memoranda book were used, then the edges of the pages were pasted together. Whenever I learned the British warships were going to put to sea, I slipped the book in my pocket, went to a position of vantage where I could make out the silhouettes of the warships, cla.s.sified them in my mind, and then writing out a cable put down the code numbers, say in this way.

214, 69, 700, 910, 21--(Necessary words were filled in by the A. B. C. code).

This message was sent by way of Brussels or Paris to the Intelligence Department of the German Admiralty in Berlin and told them what warships were putting to sea or arriving at Rossyth. The code contained such phrases as this:
