The Red Thumb Mark Part 9

"It would be a great impertinence for anyone to make any such suggestion," Mrs. Hornby began; but on Thornd.y.k.e's placing his fountain pen in her hand, she wrote her signature in the place indicated and handed the pen to Miss Gibson, who signed underneath.

"And now," said Thornd.y.k.e, "we will take an enlarged photograph of this page with the thumb-mark; not that it is necessary that it should be done now, as you are leaving the book in my possession; but the photograph will be wanted, and as my man is expecting us and has the apparatus ready, we may as well despatch the business at once."

To this both the ladies readily agreed (being, in fact, devoured by curiosity with regard to my colleague's premises), and we accordingly proceeded to invade the set of rooms on the floor above, over which the ingenious Polton was accustomed to reign in solitary grandeur.

It was my first visit to these mysterious regions, and I looked about me with as much curiosity as did the two ladies. The first room that we entered was apparently the workshop, for it contained a small woodworker's bench, a lathe, a bench for metal work and a number of mechanical appliances which I was not then able to examine; but I noticed that the entire place presented to the eye a most unworkmanlike neatness, a circ.u.mstance that did not escape Thornd.y.k.e's observation, for his face relaxed into a grim smile as his eye travelled over the bare benches and the clean-swept floor.

From this room we entered the laboratory, a large apartment, one side of which was given up to chemical research, as was shown by the shelves of reagents that covered the wall, and the flasks, retorts and other apparatus that were arranged on the bench, like ornaments on a drawing-room mantelpiece. On the opposite side of the room was a large, ma.s.sively-constructed copying camera, the front of which, carrying the lens, was fixed, and an easel or copyholder travelled on parallel guides towards, or away, from it, on a long stand.

This apparatus Thornd.y.k.e proceeded to explain to our visitors while Polton was fixing the "Thumbograph" in a holder attached to the easel.

"You see," he said, in answer to a question from Miss Gibson, "I have a good deal to do with signatures, cheques and disputed doc.u.ments of various kinds. Now a skilled eye, aided by a pocket-lens, can make out very minute details on a cheque or bank-note; but it is not possible to lend one's skilled eye to a judge or juryman, so that it is often very convenient to be able to hand them a photograph in which the magnification is already done, which they can compare with the original. Small things, when magnified, develop quite unexpected characters; for instance, you have handled a good many postage stamps, I suppose, but have you ever noticed the little white spots in the upper corner of a penny stamp, or even the difference in the foliage on the two sides of the wreath?"

Miss Gibson admitted that she had not.

"Very few people have, I suppose, excepting stamp-collectors," continued Thornd.y.k.e; "but now just glance at this and you will find these unnoticed details forced upon your attention." As he spoke, he handed her a photograph, which he had taken from a drawer, showing a penny stamp enlarged to a length of eight inches.

While the ladies were marvelling over this production, Polton proceeded with his work. The "Thumbograph" having been fixed in position, the light from a powerful incandescent gas lamp, fitted with a parabolic reflector, was concentrated on it, and the camera racked out to its proper distance.

"What are those figures intended to show?" inquired Miss Gibson, indicating the graduation on the side of one of the guides.

"They show the amount of magnification or reduction," Thornd.y.k.e explained. "When the pointer is opposite 0, the photograph is the same size as the object photographed; when it points to, say, 4, the photograph will be four times the width and length of the object, while if it should point to, say, 4, the photograph will be one-fourth the length of the object. It is now, you see, pointing to 8, so the photograph will be eight times the diameter of the original thumb-mark."

By this time Polton had brought the camera to an accurate focus and, when we had all been gratified by a glimpse of the enlarged image on the focussing screen, we withdrew to a smaller room which was devoted to bacteriology and microscopical research, while the exposure was made and the plate developed. Here, after an interval, we were joined by Polton, who bore with infinite tenderness the dripping negative on which could be seen the grotesque transparency of a colossal thumb-mark.

This Thornd.y.k.e scrutinised eagerly, and having p.r.o.nounced it satisfactory, informed Mrs. Hornby that the object of her visit was attained, and thanked her for the trouble she had taken.

"I am very glad we came," said Miss Gibson to me, as a little later we walked slowly up Mitre Court in the wake of Mrs. Hornby and Thornd.y.k.e; "and I am glad to have seen these wonderful instruments, too. It has made me realise that something is being done and that Dr. Thornd.y.k.e really has some object in view. It has really encouraged me immensely."

"And very properly so," I replied. "I, too, although I really know nothing of what my colleague is doing, feel very strongly that he would not take all this trouble and give up so much valuable time if he had not some very definite purpose and some substantial reasons for taking a hopeful view."

"Thank you for saying that," she rejoined warmly; "and you will let me have a crumb of comfort when you can, won't you?" She looked in my face so wistfully as she made this appeal that I was quite moved; and, indeed, I am not sure that my state of mind at that moment did not fully justify my colleague's reticence towards me.

However, I, fortunately, had nothing to tell, and so, when we emerged into Fleet Street to find Mrs. Hornby already ensconced in a hansom, I could only promise, as I grasped the hand that she offered to me, to see her again at the earliest opportunity-a promise which my inner consciousness a.s.sured me would be strictly fulfilled.

"You seem to be on quite confidential terms with our fair friend," Thornd.y.k.e remarked, as we strolled back towards his chambers. "You are an insinuating dog, Jervis."

"She is very frank and easy to get on with," I replied.

"Yes. A good girl and a clever girl, and comely to look upon withal. I suppose it would be superfluous for me to suggest that you mind your eye?"

"I shouldn't, in any case, try to cut out a man who is under a cloud," I replied sulkily.

"Of course you wouldn't; hence the need of attention to the ophthalmic member. Have you ascertained what Miss Gibson's actual relation is to Reuben Hornby?"

"No," I answered.

"It might be worth while to find out," said Thornd.y.k.e; and then he relapsed into silence.

CHAPTER VI

COMMITTED FOR TRIAL

Thornd.y.k.e's hint as to the possible danger foreshadowed by my growing intimacy with Juliet Gibson had come upon me as a complete surprise, and had, indeed, been resented by me as somewhat of an impertinence. Nevertheless, it gave me considerable food for meditation, and I presently began to suspect that the watchful eyes of my observant friend might have detected something in my manner towards Miss Gibson suggestive of sentiments that had been unsuspected by myself.

Of course it would be absurd to suppose that any real feeling could have been engendered by so ridiculously brief an acquaintance. I had only met the girl three times, and even now, excepting for business relations, was hardly ent.i.tled to more than a bow of recognition. But yet, when I considered the matter impartially and examined my own consciousness, I could not but recognise that she had aroused in me an interest which bore no relation to the part that she had played in the drama that was so slowly unfolding. She was undeniably a very handsome girl, and her beauty was of a type that specially appealed to me-full of dignity and character that gave promise of a splendid middle age. And her personality was in other ways not less attractive, for she was frank and open, sprightly and intelligent, and though evidently quite self-reliant, was in nowise lacking in that womanly softness that so strongly engages a man's sympathy.

In short, I realised that, had there been no such person as Reuben Hornby, I should have viewed Miss Gibson with uncommon interest.

But, unfortunately, Reuben Hornby was a most palpable reality, and, moreover, the extraordinary difficulties of his position ent.i.tled him to very special consideration by any man of honour. It was true that Miss Gibson had repudiated any feelings towards Reuben other than those of old-time friendship; but young ladies are not always impartial judges of their own feelings, and, as a man of the world, I could not but have my own opinion on the matter-which opinion I believed to be shared by Thornd.y.k.e. The conclusions to which my cogitations at length brought me were: first, that I was an egotistical donkey, and, second, that my relations with Miss Gibson were of an exclusively business character and must in future be conducted on that basis, with the added consideration that I was the confidential agent, for the time being, of Reuben Hornby, and in honour bound to regard his interests as paramount.

"I am hoping," said Thornd.y.k.e, as he held out his hand for my teacup, "that these profound reflections of yours are connected with the Hornby affair; in which case I should expect to hear that the riddle is solved and the mystery made plain."

"Why should you expect that?" I demanded, reddening somewhat, I suspect, as I met his twinkling eye. There was something rather disturbing in the dry, quizzical smile that I encountered and the reflection that I had been under observation, and I felt as much embarra.s.sed as I should suppose a self-conscious water-flea might feel on finding itself on the illuminated stage of a binocular microscope.

"My dear fellow," said Thornd.y.k.e, "you have not spoken a word for the last quarter of an hour; you have devoured your food with the relentless regularity of a sausage-machine, and you have, from time to time, made the most d.a.m.nable faces at the coffee-pot-though there I'll wager the coffee-pot was even with you, if I may judge by the presentment that it offers of my own countenance."

I roused myself from my reverie with a laugh at Thornd.y.k.e's quaint conceit and a glance at the grotesquely distorted reflection of my face in the polished silver.

"I am afraid I have been a rather dull companion this morning," I admitted apologetically.

"By no means," replied Thornd.y.k.e, with a grin. "On the contrary, I have found you both amusing and instructive, and I only spoke when I had exhausted your potentialities as a silent entertainer."

"You are pleased to be facetious at my expense," said I.

"Well, the expense was not a very heavy one," he retorted. "I have been merely consuming a by-product of your mental activity-Hallo! that's Anstey already."

A peculiar knock, apparently delivered with the handle of a walking-stick on the outer door, was the occasion of this exclamation, and as Thornd.y.k.e sprang up and flung the door open, a clear, musical voice was borne in, the measured cadences of which proclaimed at once the trained orator.

"Hail, learned brother!" it exclaimed. "Do I disturb you untimely at your studies?" Here our visitor entered the room and looked round critically. "'Tis even so," he declared. "Physiological chemistry and its practical applications appears to be the subject. A physico-chemical inquiry into the properties of streaky bacon and fried eggs. Do I see another learned brother?"

He peered keenly at me through his pince-nez, and I gazed at him in some embarra.s.sment.

"This is my friend Jervis, of whom you have heard me speak," said Thornd.y.k.e. "He is with us in this case, you know."

"The echoes of your fame have reached me, sir," said Anstey, holding out his hand. "I am proud to know you. I should have recognised you instantly from the portrait of your lamented uncle in Greenwich Hospital."

"Anstey is a wag, you understand," explained Thornd.y.k.e, "but he has lucid intervals. He'll have one presently if we are patient."

"Patient!" snorted our eccentric visitor, "it is I who need to be patient when I am dragged into police courts and other sinks of iniquity to plead for common thieves and robbers like a Kennington Lane advocate."
