Commenting upon one of my earlier novels, in respect of which I had claimed to have been careful to adhere to common probabilities and to have made use only of really practicable methods of investigation, a critic remarked that this was of no consequence whatever, so long as the story was amusing. Few people, I imagine, will agree with him. To most readers, and certainly to the kind of reader for whom an author is willing to take trouble, complete realism in respect of incidents and methods is a

As I look back through the years of my association with John Thorndyke, I am able to recall a wealth of adventures and strange experiences such as falls to the lot of very few men who pass their lives within hearing of Big Ben. Many of these experiences I have already placed on record; but it now occurs to me that I have hitherto left unrecorded one that is, perhaps, the most astonishing and incredible of the whole series; an adventure, too, that has for me the added interest that it inaugurated

As I entered the Temple by the Tudor Street gate the aspect of the place smote my senses with an air of agreeable familiarity. Here had I spent many a delightful hour when working with Thorndyke at the remarkable Hornby case, which the newspapers had called "The Case of the Red Thumb Mark"; and here had I met the romance of my life, the story whereof is told elsewhere. The place was thus endeared to me by pleasant recollections of a happy past, and its associations suggested hopes of happiness y

The attitude of the suspicious man tends to generate in others the kind of conduct that seems to justify his suspicions. In most of us there lurks a certain strain of mischief which trustfulness disarms but distrust encourages. The inexperienced kitten which approaches us confidingly with arched back and upright tail, soliciting caresses, generally receives the gentle treatment that it expects; whereas the worldly-wise tom-cat, who, in response to friendly advances, scampers away and grins at us

I rose on the following morning still possessed by the determination to make some oportunity during the day to call on Thorndyke and take his advice on the now urgent question as to what I was to do. I use the word "urgent" advisedly; for the incidents of the preceding evening had left me with the firm conviction that poison was being administered for some purpose to my mysterious patient, and that no time must be lost if his life was to be saved. Last night he had escaped only by the narrowest

My arrival at Thorndyke's chambers was not unexpected, having been heralded by a premonitory post-card. The "oak" was open and an application of the little brass knocker of the inner door immediately produced my colleague himself and a very hearty welcome. "At last," said Thorndyke, "you have come forth from the house of bondage. I began to think that you had taken up your abode in Kennington for good." "I was beginning, myself, to wonder when I should escape. But here I am; and I may say at onc

Having made the above proposition, Thorndyke placed a fresh slip of paper on the blotting pad on his knee and looked inquiringly at Mr. Marchmont; who, in his turn, sighed and looked at the bundle of documents on the table. "What do you want to know?" he asked a little wearily. "Everything," replied Thorndyke. "You have hinted at circumstances that would account for a change in Jeffrey's habits and that would explain an alteration in the character of his signature. Let us have those circumstance

The surprise which Thorndyke's proceedings usually occasioned, especially to lawyers, was principally due, I think, to my friend's habit of viewing occurrences from an unusual standpoint. He did not look at things quite as other men looked at them. He had no prejudices and he knew no conventions. When other men were cocksure, Thorndyke was doubtful. When other men despaired, he entertained hopes; and thus it happened that he would often undertake cases that had been rejected contemptuously by ex

As Thorndyke and I arrived at the main gateway of the Temple and he swung round into the narrow lane, it was suddenly borne in on me that I had made no arrangements for the night. Events had followed one another so continuously and each had been so engrossing that I had lost sight of what I may call my domestic affairs. "We seem to be heading for your chambers, Thorndyke," I ventured to remark. "It is a little late to think of it, but I have not yet settled where I am to put up to-night." "My de

Half-past nine on the following morning found us spinning along the Albert Embankment in a hansom to the pleasant tinkle of the horse's bell. Thorndyke appeared to be in high spirits, though the full enjoyment of the matutinal pipe precluded fluent conversation. As a precaution, he had put my notebook in his pocket before starting, and once or twice he took it out and looked over its pages; but he made no reference to the object of our quest, and the few remarks that he uttered would have indica

The omnibus of those days was a leisurely vehicle. Its ordinary pace was a rather sluggish trot, and in a thickly populated thoroughfare its speed was further reduced by frequent stoppages. Bearing these facts in mind, I gave an occasional backward glance as we jogged northward, though my attention soon began to wander from the rather remote possibility of pursuit to the incidents of our late exploration. It had not been difficult to see that Thorndyke was very well pleased with the results of o

One of the conditions of medical practice is the capability of transferring one's attention at a moment's notice from one set of circumstances to another equally important but entirely unrelated. At each visit on his round, the practitioner finds himself concerned with a particular, self-contained group of phenomena which he must consider at the moment with the utmost concentration, but which he must instantly dismiss from his mind as he moves on to the next case. It is a difficult habit to acqu

The state of mind which Thorndyke had advised me to cultivate was one that did not come easily. However much I endeavoured to shuffle the facts of the Blackmore case, there was one which inevitably turned up on the top of the pack. The circumstances surrounding the execution of Jeffrey Blackmore's will intruded into all my cogitations on the subject with hopeless persistency. That scene in the porter's lodge was to me what King Charles's head was to poor Mr. Dick. In the midst of my praiseworthy

As soon as I was alone, I commenced my investigations with a rather desperate hope of eliciting some startling and unsuspected facts. I opened the drawer and taking from it the two pieces of reed and the shattered remains of the spectacles, laid them on the table. The repairs that Thorndyke had contemplated in the case of the spectacles, had not been made. Apparently they had not been necessary. The battered wreck that lay before me, just as we had found it, had evidently furnished the necessary

The information supplied by Mr. Samuel Wilkins, so far from dispelling the cloud of mystery that hung over the Blackmore case, only enveloped it in deeper obscurity, so far as I was concerned. The new problem that Thorndyke offered for solution was a tougher one than any of the others. He proposed that I should identify and give a name to this mysterious woman. But how could I? No woman, excepting Mrs. Wilson, had been mentioned in connection with the case. This new dramatis persona had appeared

We had not been back in our chambers more than a few minutes when the little brass knocker on the inner door rattled out its summons. Thorndyke himself opened the door, and, finding our three expected visitors on the threshold, he admitted them and closed the "oak." "We have accepted your invitation, you see," said Marchmont, whose manner was now a little flurried and uneasy. "This is my partner, Mr. Winwood; you haven't met before, I think. Well, we thought we should like to hear some further p

"You may have wondered," Thorndyke commenced, when he had poured out the coffee and handed round the cups, "what induced me to undertake the minute investigation of so apparently simple and straightforward a case. Perhaps I had better explain that first and let you see what was the real starting-point of the inquiry. "When you, Mr. Marchmont and Mr. Stephen, introduced the case to me, I made a very brief précis of the facts as you presented them, and of these there were one or two which immediat
