"After they got me inside--for the other men sprang to my captor's assistance--they closed and locked the door, also the transom, and began to quiz me as to what I was doing out in the hall. I was too sore at their treatment of me to give an explanation and demanded what they meant by their actions. I saw that they were very uneasy about something and that made me bolder. It soon dawned upon me that they had been doing something that they wanted to keep secret. That resolved me to get back at them with interest, and while they were busy with their excited demands, I got my wits together to devise some sort of trick that would show them it wasn't quite so easy to browbeat me as they seemed to imagine.
"All three of them huddled together right in front of me and rained questions at me excitedly. This suited me first rate as soon as I had decided what to do. I wasn't afraid of any desperate violence on their part; the place was too public for that. I retreated slowly to the table at which they had been working and leaned back resting my hands on it. They never caught on to what I was up to, but pressed close to me with their excited questions. I met these with noncommittal replies, and at the same time got one hand closer and closer to the mysterious slip of paper on the table. It was not more than six inches long and three wide, and I figured that if I could get one hand on it I might crumple it in my fist without their observing what I was doing. After I had been dragged into the room, I saw the young fellow hurriedly draw down the sleeve of his shirt over the tattooed portion of his forearm. He seemed so nervous while doing this that my suspicion of something wrong became very acute; and yet, the mystery could hardly have been more baffling.
"Well, I got my hand on the paper and crumpled it in my fist, and they never got onto my trick, at least, not until I got out of that room and away from them. I was now ready to answer their questions. I told them I was a patient in the hospital and was just trying to find my way to the office and started down the wrong stairway--that was all there was to it. I then demanded that they release me at once or I would make serious trouble for them. They asked me my name, and I told them. Then the bearded man left the laboratory, and I presume he went to the office to make inquiry about me, for he came back in a few minutes and reported that he guessed I was all right. But they held a whispered conversation in German--I caught enough of their words to be sure of that--and then told me I might go. But before the door was unlocked, the bearded man apologized, as nearly as I can remember, in the following words:
"I hope you will forgive our rough conduct, but we are engaged in very important government work, and when we saw you looking through the glass at us and apparently listening to our conversation, we presumed you were a German spy. You have satisfied us that you are all right, and we recommend that, as you love your country and wish to aid us to win the war, you keep this affair strictly to yourself."
"I was astonished and more confused than ever. That statement convicted them of something on the face of it, but of what I could not conjecture. The idea that a responsible secret agent of the government should make such a speech as that under any circumstances was simply ridiculous. I was mighty sure they were not doing work for the government. They were trying to cover something up, but what I could make no rational guess.
"I decided not to remain in the hospital any longer than it would take to get my few belongings together and pay my bill. I was afraid they would discover the loss of the paper I had stolen. Well, I got out of that place so rapidly that I had everybody staring at me who beheld my movements.
"I went to a hotel, but I am dead sure I was followed. In the morning when I went down to breakfast I was conscious of being watched. I telephoned to my friend, but while in the booth I glanced about with apparent unconcern and caught one of my shadowers looking in my direction over the top of a newspaper from a seat in the hotel lobby. I met my friend, but said nothing to him about my adventure. I wanted to get back home as soon as possible. I wasn't in condition physically to undergo any great strain.
"At last I was on the train and speeding toward home, but hadn't covered more than half of the journey when I discovered that one of my shadowers was making the journey with me. He got off when I got off and for several days had a room in one of our local hotels. I talked the matter over with father and we came to the conclusion that I had fallen into a nest of the kaiser's spies. We examined the paper I had taken from the table in the laboratory of the Toronto hospital and I made a copy of it. Then we went to the chief of police and I told nay story to him. He said the matter ought to be taken up with government officials and asked me to let him show the mysterious paper in my possession to them. I had expected this, and gave him the paper.
"A few days later I read in a newspaper that the hospital had been raided by government agents. Also, I saw nothing more of the fellow who had followed me from Toronto after I made my report to the chief of police.
"Now, what do you think of all this? Isn't it some adventure? I'm sending to you, just for your amusement, a copy of the drawing on the paper that I stole from the hospital laboratory. Can you make anything out of it? It may afford you some diversion during long, dreary watches in camp, trench or dugout."
