“Conflagratam Anno 1677.  Fabricatam Anno 1698.  Richardo Powell Armiger Thesaurar.”  The words, set in four panels, which formed a frieze beneath the pediment of a fine brick portico, summarised the history of one of the tall houses at the upper end of King’s Bench Walk and as I, somewhat absently, read over the inscription, my attention was divided between admiration of the exquisitely finished carved brickwork and the quiet dignity of the building, and an effort to reconstitute the dead and gone Richard Powell, and the stirring times in which he played his part.

I was about to turn away when the empty frame of the portico became occupied by a figure, and one so appropriate, in its wig and obsolete habiliments, to the old-world surroundings that it seemed to complete the picture, and I lingered idly to look at it.  The barrister had halted in the doorway to turn over a sheaf of papers that he held in his hand, and, as he replaced the red tape which bound them together, he looked up and our eyes met.  For a moment we regarded one another with the incurious gaze that casual strangers bestow on one another; then there was a flash of mutual recognition; the impassive and rather severe face of the lawyer softened into a genial smile, and the figure, detaching itself from its frame, came down the steps with a hand extended in cordial greeting.

“My dear Jervis,” he exclaimed, as we clasped hands warmly, “this is a great and delightful surprise.  How often have I thought of my old comrade and wondered if I should ever see him again, and lo! here he is, thrown up on the sounding beach of the Inner Temple, like the proverbial bread cast upon the waters.”

“Your surprise, Thorndyke, is nothing to mine,” I replied, “for your bread has at least returned as bread; whereas I am in the position of a man who, having cast his bread upon the waters, sees it return in the form of a buttered muffin or a Bath bun.  I left a respectable medical practitioner and I find him transformed into a bewigged and begowned limb of the law.”

Thorndyke laughed at the comparison.

“Liken not your old friend unto a Bath bun,” said he.  “Say, rather, that you left him a chrysalis and come back to find him a butterfly.  But the change is not so great as you think.  Hippocrates is only hiding under the gown of Solon, as you will understand when I explain my metamorphosis; and that I will do this very evening, if you have no engagement.”

“I am one of the unemployed at present,” I said, “and quite at your service.”

“Then come round to my chambers at seven,” said Thorndyke, “and we will have a chop and a pint of claret together and exchange autobiographies.  I am due in court in a few minutes.”

“Do you reside within that noble old portico?” I asked.

“No,” replied Thorndyke.  “I often wish I did.  It would add several inches to one’s stature to feel that the mouth of one’s burrow was graced with a Latin inscription for admiring strangers to ponder over.  No; my chambers are some doors further down ­number 6A” ­and he turned to point out the house as we crossed towards Crown Office Row.

At the top of Middle Temple Lane we parted, Thorndyke taking his way with fluttering gown towards the Law Courts, while I directed my steps westward towards Adam Street, the chosen haunt of the medical agent.

The soft-voiced bell of the Temple clock was telling out the hour of seven in muffled accents (as though it apologised for breaking the studious silence) as I emerged from the archway of Mitre Court and turned into King’s Bench Walk.

The paved footway was empty save for a single figure, pacing slowly before the doorway of number 6A, in which, though the wig had now given place to a felt hat and the gown to a jacket, I had no difficulty in recognising my friend.

“Punctual to the moment, as of old,” said he, meeting me half-way.  “What a blessed virtue is punctuality, even in small things.  I have just been taking the air in Fountain Court, and will now introduce you to my chambers.  Here is my humble retreat.”

We passed in through the common entrance and ascended the stone stairs to the first floor, where we were confronted by a massive door, above which my friend’s name was written in white letters.  “Rather a forbidding exterior,” remarked Thorndyke, as he inserted the latchkey, “but it is homely enough inside.”

The heavy door swung outwards and disclosed a baize-covered inner door, which Thorndyke pushed open and held for me to pass in.

“You will find my chambers an odd mixture,” said Thorndyke, “for they combine the attractions of an office, a museum, a laboratory and a workshop.”

“And a restaurant,” added a small, elderly man, who was decanting a bottle of claret by means of a glass syphon:  “you forgot that, sir.”

“Yes, I forgot that, Polton,” said Thorndyke, “but I see you have not.”  He glanced towards a small table that had been placed near the fire and set out with the requisites for our meal.

“Tell me,” said Thorndyke, as we made the initial onslaught on the products of Polton’s culinary experiments, “what has been happening to you since you left the hospital six years ago?”

“My story is soon told,” I answered, somewhat bitterly.  “It is not an uncommon one.  My funds ran out, as you know, rather unexpectedly.  When I had paid my examination and registration fees the coffer was absolutely empty, and though, no doubt, a medical diploma contains ­to use Johnson’s phrase ­the potentiality of wealth beyond the dreams of avarice, there is a vast difference in practice between the potential and the actual.  I have, in fact, been earning a subsistence, sometimes as an assistant, sometimes as a locum tenens.  Just now I’ve got no work to do, and so have entered my name on Turcival’s list of eligibles.”

Thorndyke pursed up his lips and frowned.

“It’s a wicked shame, Jervis,” said he presently, “that a man of your abilities and scientific acquirements should be frittering away his time on odd jobs like some half-qualified wastrel.”

“It is,” I agreed.  “My merits are grossly undervalued by a stiff-necked and obtuse generation.  But what would you have, my learned brother?  If poverty steps behind you and claps the occulting bushel over your thirty thousand candle-power luminary, your brilliancy is apt to be obscured.”

“Yes, I suppose that is so,” grunted Thorndyke, and he remained for a time in deep thought.

“And now,” said I, “let us have your promised explanation.  I am positively frizzling with curiosity to know what chain of circumstances has converted John Evelyn Thorndyke from a medical practitioner into a luminary of the law.”

Thorndyke smiled indulgently.

“The fact is,” said he, “that no such transformation has occurred.  John Evelyn Thorndyke is still a medical practitioner.”

“What, in a wig and gown!” I exclaimed.

“Yes, a mere sheep in wolf’s clothing,” he replied.  “I will tell you how it has come about.  After you left the hospital, six years ago, I stayed on, taking up any small appointments that were going ­assistant demonstrator ­or curatorships and such like ­hung about the chemical and physical laboratories, the museum and post mortem room, and meanwhile took my M.D. and D.Sc.  Then I got called to the bar in the hope of getting a coronership, but soon after this, old Stedman retired unexpectedly ­you remember Stedman, the lecturer on medical jurisprudence ­and I put in for the vacant post.  Rather to my surprise, I was appointed lecturer, whereupon I dismissed the coronership from my mind, took my present chambers and sat down to wait for anything that might come.”  “And what has come?” I asked.

“Why, a very curious assortment of miscellaneous practice,” he replied.  “At first I only got an occasional analysis in a doubtful poisoning case, but, by degrees, my sphere of influence has extended until it now includes all cases in which a special knowledge of medicine or physical science can be brought to bear upon law.”

“But you plead in court, I observe,” said I.

“Very seldom,” he replied.  “More usually I appear in the character of that bête noir of judges and counsel ­the scientific witness.  But in most instances I do not appear at all; I merely direct investigations, arrange and analyse the results, and prime the counsel with facts and suggestions for cross-examination.”

“A good deal more interesting than acting as understudy for an absent g.p.,” said I, a little enviously.  “But you deserve to succeed, for you were always a deuce of a worker, to say nothing of your capabilities.”

“Yes, I worked hard,” replied Thorndyke, “and I work hard still; but I have my hours of labour and my hours of leisure, unlike you poor devils of general practitioners, who are liable to be dragged away from the dinner table or roused out of your first sleep by ­confound it all! who can that be?”

For at this moment, as a sort of commentary on his self-congratulation, there came a smart rapping at the outer door.

“Must see who it is, I suppose,” he continued, “though one expects people to accept the hint of a closed oak.”

He strode across the room and flung open the door with an air of by no means gracious inquiry.

“It’s rather late for a business call,” said an apologetic voice outside, “but my client was anxious to see you without delay.”

“Come in, Mr. Lawley,” said Thorndyke, rather stiffly, and, as he held the door open, the two visitors entered.  They were both men ­one middle-aged, rather foxy in appearance and of a typically legal aspect, and the other a fine, handsome young fellow of very prepossessing exterior, though at present rather pale and wild-looking, and evidently in a state of profound agitation.

“I am afraid,” said the latter, with a glance at me and the dinner table, “that our visit ­for which I am alone responsible ­is a most unseasonable one.  If we are really inconveniencing you, Dr. Thorndyke, pray tell us, and my business must wait.”

Thorndyke had cast a keen and curious glance at the young man, and he now replied in a much more genial tone ­

“I take it that your business is of a kind that will not wait, and as to inconveniencing us, why, my friend and I are both doctors, and, as you are aware, no doctor expects to call any part of the twenty-four hours his own unreservedly.”

I had risen on the entrance of the two strangers, and now proposed to take a walk on the Embankment and return later, but the young man interrupted me.

“Pray don’t go away on my account,” he said.  “The facts that I am about to lay before Dr. Thorndyke will be known to all the world by this time to-morrow, so there is no occasion for any show of secrecy.”

“In that case,” said Thorndyke, “let us draw our chairs up to the fire and fall to business forthwith.  We had just finished our dinner and were waiting for the coffee, which I hear my man bringing down at this moment.”

We accordingly drew up our chairs, and when Polton had set the coffee on the table and retired, the lawyer plunged into the matter without preamble.
