at the cover of the dainty little notebook for many minutes before he opened it. It was a couple of inches long, of the usual form, and had a cover of brown leather. In the left upper corner were the letters A. L. in gold. The leaves of the book, about fifty in all, were of a fine quality of paper and covered with close writing. On the first leaves the writing was fine and delicate, calm and orderly, but later on it was irregular and uncertain, as if penned by a trembling hand under stress of terror. This change came in the leaves of the book which followed the strange and terrible title, "How I was murdered."

Before Muller began to read he felt the covers of the book carefully. In one of them there was a tiny pocket, in which he found a little piece of wall paper of a noticeable and distinctly ugly pattern. The paper had a dark blue ground with clumsy lines of gold on it. In the pocket he found also a tramway ticket, which had been crushed and then carefully smoothed out again. After looking at these papers, Muller replaced them in the cover of the notebook. The book itself was strongly perfumed with the same odour which had exhaled from the handkerchief.

The detective did not begin his reading in that part of the book which followed the mysterious title, as the commissioner had done. He began instead at the very first words.

"Ah! she is still young," he murmured, when he had read the first lines. "Young, in easy circumstances, happy and contented."

These first pages told of pleasure trips, of visits from and to good friends, of many little events of every-day life. Then came some accounts, written in pencil, of shopping expeditions to the city. Costly laces and jewels had been bought, and linen garments for children by the dozen. "She is rich, generous, and charitable," thought the detective, for the book showed that the considerable sums which had been spent here had not been for the writer herself. The laces bore the mark, "For our church"; behind the account for the linen stood the words, "For the charity school."

Muller began to feel a strong sympathy for the writer of these notices. She showed an orderly, almost pedantic, character, mingled with generosity of heart. He turned leaf after leaf until he finally came to the words, written in intentionally heavy letters, "How I was murdered."

Muller's head sank down lower over these mysterious words, and his eyes flew through the writing that followed. It was quite a different writing here. The hand that penned these words must have trembled in deadly terror. Was it terror of coming death, foreseen and not to be escaped? or was it the trembling and the terror of an overthrown brain? It was undoubtedly, in spite of the difference, the same hand that had penned the first pages of the book. A few characteristic turns of the writing were plainly to be seen in both parts of the story. But the ink was quite different also. The first pages had been written with a delicate violet ink, the later leaves were penned with a black ink of uneven quality, of the kind used by poor people who write very seldom. The words of this later portion of the book were blurred in many places, as if the writer had not been able to dry them properly before she turned the leaves. She therefore had had neither blotting paper nor sand at her disposal.

And then the weird title!

Was it written at the dictation of insanity? or did A. L. know, while she wrote it, that it was too late for any help to reach her? Did she see her doom approaching so clearly that she knew there was no escape?

Muller breathed a deep breath before he continued his reading. Later on his breath came more quickly still, and he clinched his fist several times, as if deeply moved. He was not a cold man, only thoroughly self-controlled. In his breast there lived an unquenchable hatred of all evil. It was this that awakened the talents which made him the celebrated detective he had become.

"I fear that it will be impossible for any one to save me now, but perhaps I may be avenged. Therefore I will write down here all that has happened to me since I set out on my journey." These were the first words that were written under the mysterious title. Muller had just read them when the commissioner entered.

"Will you speak to Amster; he has just returned?" he asked.

Muller rose at once. "Certainly. Did you telegraph to all the railway stations?"

"Yes," answered the commissioner, "and also to the other police stations."

"And to the hospitals?—asylums?"

"No, I did not do that." Commissioner von Mayringen blushed, a blush that was as becoming to him as was his frank acknowledgment of his mistake. He went out to remedy it at once, while Muller heard Amster's short and not particularly important report. The workingman was evidently shivering, and the detective handed him a glass of tea with a good portion of rum in it.

"Here, drink this; you are cold. Are you ill?" Amster smiled sadly. "No, I am not ill, but I was discharged to-day and am out of work now—that's almost as bad."

"Are you married?"

"No, but I have an old mother to support."

"Leave your address with the commissioner. He may be able to find work for you; we can always use good men here. But now drink your tea." Amster drank the glass in one gulp. "Well, now we have lost the trail in both directions," said Muller calmly. "But we will find it again. You can help, as you are free now anyway. If you have the talent for that sort of thing, you may find permanent work here."

A gesture and a look from the workingman showed the detective that the former did not think very highly of such occupation. Muller laid his hand on the other's shoulder and said gravely: "You wouldn't care to take service with us? This sort of thing doesn't rate very high, I know. But I tell you that if we have our hearts in the right place, and our brains are worth anything, we are of more good to humanity than many an honest citizen who wouldn't shake hands with us. There—and now I am busy. Goodnight."

With these words Muller pushed the astonished man out of the room, shut the door, and sat down again with his little book. This is what he read:

"Wednesday—is it Wednesday? They brought me a newspaper to-day which had the date of Wednesday, the 20th of November. The ink still smells fresh, but it is so damp here, the paper may have been older. I do not know surely on what day it is that I begin to write this narrative. I do not know either whether I may not have been ill for days and weeks; I do not know what may have been the matter with me—I know only that I was unconscious, and that when I came to myself again, I was here in this gloomy room. Did any physician see me? I have seen no one until to-day except the old woman, whose name I do not know and who has so little to say. She is kind to me otherwise, but I am afraid of her hard face and of the smile with which she answers all my questions and entreaties. 'You are ill.' These are the only words that she has ever said to me, and she pointed to her forehead as she spoke them. She thinks I am insane, therefore, or pretends to think so.

"What a hoarse voice she has. She must be ill herself, for she coughs all night long. I can hear it through the wall—she sleeps in the next room. But I am not ill, that is I am not ill in the way she says. I have no fever now, my pulse is calm and regular. I can remember everything, until I took that drink of tea in the railway station. What could there have been in that tea? I suppose I should have noticed how anxious my travelling companion was to have me drink it.

"Who could the man have been? He was so polite, so fatherly in his anxiety about me. I have not seen him since then. And yet I feel that it is he who has brought me into this trap, a trap from which I may never escape alive. I will describe him. He is very tall, stout and blond, and wears a long heavy beard, which is slightly mixed with grey. On his right cheek his beard only partly hides a long scar. His eyes are
