"You might set me down at King's Cross if it is not delaying you;" and giving the word to the cabman, I took my place by her side as the cab started and a black-painted prison van turned into the courtyard with its freight of squalid misery.

"I don't think Reuben was very pleased to see me," Miss Gibson remarked presently, "but I shall come again all the same. It is a duty I owe both to him and to myself."

I felt that I ought to endeavour to dissuade her, but the reflection that her visits must almost of necessity involve my companionship, enfeebled my will. I was fast approaching a state of infatuation.

"I was so thankful," she continued, "that you prepared me. It was a horrible experience to see the poor fellow caged like a wild beast, with that dreadful label hanging from his coat; but it would have been overwhelming if I had not known what to expect."

As we proceeded, her spirits revived somewhat, a circ.u.mstance that she graciously ascribed to the enlivening influence of my society; and I then told her of the mishap that had befallen my colleague.

"What a terrible thing!" she exclaimed, with evidently unaffected concern. "It is the merest chance that he was not killed on the spot. Is he much hurt? And would he mind, do you think, if I called to inquire after him?"

I said that I was sure he would be delighted (being, as a matter of fact, entirely indifferent as to his sentiments on the subject in my delight at the proposal), and when I stepped down from the cab at King's Cross to pursue my way homewards, there already opened out before me the prospect of the renewal of this bitter-sweet and all too dangerous companionship on the morrow.

CHAPTER X

POLTON IS MYSTIFIED

A couple of days sufficed to prove that Thornd.y.k.e's mishap was not to be productive of any permanent ill consequences; his wounds progressed favourably and he was able to resume his ordinary avocations.

Miss Gibson's visit-but why should I speak of her in these formal terms? To me, when I thought of her, which I did only too often, she was Juliet, with perhaps an adjective thrown in; and as Juliet I shall henceforth speak of her (but without the adjective) in this narrative, wherein nothing has been kept back from the reader-Juliet's visit, then, had been a great success, for my colleague was really pleased by the attention, and displayed a quiet geniality that filled our visitor with delight.

He talked a good deal of Reuben, and I could see that he was endeavouring to settle in his own mind the vexed question of her relations with and sentiments towards our unfortunate client; but what conclusions he arrived at I was unable to discover, for he was by no means communicative after she had left. Nor was there any repet.i.tion of the visit-greatly to my regret-since, as I have said, he was able, in a day or two, to resume his ordinary mode of life.

The first evidence I had of his renewed activity appeared when I returned to the chambers at about eleven o'clock in the morning, to find Polton hovering dejectedly about the sitting-room, apparently perpetrating as near an approach to a "spring clean" as could be permitted in a bachelor establishment.

"Hallo, Polton!" I exclaimed, "have you contrived to tear yourself away from the laboratory for an hour or two?"

"No, sir," he answered gloomily. "The laboratory has torn itself away from me."

"What do you mean?" I asked.

"The Doctor has shut himself in and locked the door, and he says I am not to disturb him. It will be a cold lunch to-day."

"What is he doing in there?" I inquired.

"Ah!" said Polton, "that's just what I should like to know. I'm fair eaten up with curiosity. He is making some experiments in connection with some of his cases, and when the Doctor locks himself in to make experiments, something interesting generally follows. I should like to know what it is this time."

"I suppose there is a keyhole in the laboratory door?" I suggested, with a grin.

"Sir!" he exclaimed indignantly. "Dr. Jervis, I am surprised at you." Then, perceiving my facetious intent, he smiled also and added: "But there is a keyhole if you'd like to try it, though I'll wager the Doctor would see more of you than you would of him."

"You are mighty secret about your doings, you and the Doctor," I said.

"Yes," he answered. "You see, it's a queer trade this of the Doctor's, and there are some queer secrets in it. Now, for instance, what do you make of this?"

He produced from his pocket a leather case, whence he took a piece of paper which he handed to me. On it was a neatly executed drawing of what looked like one of a set of chessmen, with the dimensions written on the margin.

"It looks like a p.a.w.n-one of the Staunton pattern," I said.

"Just what I thought; but it isn't. I've got to make twenty-four of them, and what the Doctor is going to do with them fairly beats me."

"Perhaps he has invented some new game," I suggested facetiously.

"He is always inventing new games and playing them mostly in courts of law, and then the other players generally lose. But this is a puzzler, and no mistake. Twenty-four of these to be turned up in the best-seasoned boxwood! What can they be for? Something to do with the experiments he is carrying on upstairs at this very moment, I expect." He shook his head, and, having carefully returned the drawing to his pocket-book, said, in a solemn tone-"Sir, there are times when the Doctor makes me fairly dance with curiosity. And this is one of them."

Although not afflicted with a curiosity so acute as that of Polton, I found myself speculating at intervals on the nature of my colleague's experiments and the purpose of the singular little objects which he had ordered to be made; but I was unacquainted with any of the cases on which he was engaged, excepting that of Reuben Hornby, and with the latter I was quite unable to connect a set of twenty-four boxwood chessmen. Moreover, on this day, I was to accompany Juliet on her second visit to Holloway, and that circ.u.mstance gave me abundant mental occupation of another kind.

At lunch, Thornd.y.k.e was animated and talkative but not communicative. He "had some work in the laboratory that he must do himself," he said, but gave no hint as to its nature; and as soon as our meal was finished, he returned to his labours, leaving me to pace up and down the walk, listening with ridiculous eagerness for the sound of the hansom that was to transport me to the regions of the blest, and-incidentally-to Holloway Prison.

When I returned to the Temple, the sitting-room was empty and hideously neat, as the result of Polton's spring-cleaning efforts. My colleague was evidently still at work in the laboratory, and, from the circ.u.mstance that the tea-things were set out on the table and a kettle of water placed in readiness on the gas-ring by the fireplace, I gathered that Polton also was full of business and anxious not to be disturbed.

Accordingly, I lit the gas and made my tea, enlivening my solitude by turning over in my mind the events of the afternoon.

Juliet had been charming-as she always was-frank, friendly and unaffectedly pleased to have my companionship. She evidently liked me and did not disguise the fact-why should she indeed?-but treated me with a freedom, almost affectionate, as though I had been a favourite brother; which was very delightful, and would have been more so if I could have accepted the relationship. As to her feelings towards me, I had not the slightest misgiving, and so my conscience was clear; for Juliet was as innocent as a child, with the innocence that belongs to the direct, straightforward nature that neither does evil itself nor looks for evil motives in others. For myself, I was past praying for. The thing was done and I must pay the price hereafter, content to reflect that I had trespa.s.sed against no one but myself. It was a miserable affair, and many a heartache did it promise me in the lonely days that were to come, when I should have said "good-bye" to the Temple and gone back to my old nomadic life; and yet I would not have had it changed if I could; would not have bartered the bitter-sweet memories for dull forgetfulness.

But other matters had transpired in the course of our drive than those that loomed so large to me in the egotism of my love. We had spoken of Mr. Hornby and his affairs, and from our talk there had emerged certain facts of no little moment to the inquiry on which I was engaged.

"Misfortunes are proverbially sociable," Juliet had remarked, in reference to her adopted uncle. "As if this trouble about Reuben were not enough, there are worries in the city. Perhaps you have heard of them."

I replied that Walter had mentioned the matter to me.

"Yes," said Juliet rather viciously; "I am not quite clear as to what part that good gentleman has played in the matter. It has come out, quite accidentally, that he had a large holding in the mines himself, but he seems to have 'cut his loss,' as the phrase goes, and got out of them; though how he managed to pay such large differences is more than we can understand. We think he must have raised money somehow to do it."

"Do you know when the mines began to depreciate?" I asked.

"Yes, it was quite a sudden affair-what Walter calls 'a slump'-and it occurred only a few days before the robbery. Mr. Hornby was telling me about it only yesterday, and he recalled it to me by a ridiculous accident that happened on that day."

"What was that?" I inquired.

"Why, I cut my finger and nearly fainted," she answered, with a shamefaced little laugh. "It was rather a bad cut, you know, but I didn't notice it until I found my hand covered with blood. Then I turned suddenly faint, and had to lie down on the hearthrug-it was in Mr. Hornby's study, which I was tidying up at the time. Here I was found by Reuben, and a dreadful fright it gave him at first; and then he tore up his handkerchief to tie up the wounded finger, and you never saw such an awful mess as he got his hands in. He might have been arrested as a murderer, poor boy, from the condition he was in. It will make your professional gorge rise to learn that he fastened up the extemporised bandage with red tape, which he got from the writing table after rooting about among the sacred papers in the most ruthless fashion.

"When he had gone I tried to put the things on the table straight again, and really you might have thought some horrible crime had been committed; the envelopes and papers were all smeared with blood and marked with the print of gory fingers. I remembered it afterwards, when Reuben's thumb-mark was identified, and thought that perhaps one of the papers might have got into the safe by accident; but Mr. Hornby told me that was impossible; he tore the leaf off his memorandum block at the time when he put away the diamonds."

Such was the gist of our conversation as the cab rattled through the streets on the way to the prison; and certainly it contained matter sufficiently important to draw away my thoughts from other subjects, more agreeable, but less relevant to the case. With a sudden remembrance of my duty, I drew forth my notebook, and was in the act of committing the statements to writing, when Thornd.y.k.e entered the room.

"Don't let me interrupt you, Jervis," said he. "I will make myself a cup of tea while you finish your writing, and then you shall exhibit the day's catch and hang your nets out to dry."

I was not long in finishing my notes, for I was in a fever of impatience to hear Thornd.y.k.e's comments on my latest addition to our store of information. By the time the kettle was boiling my entries were completed, and I proceeded forthwith to retail to my colleague those extracts from my conversation with Juliet that I have just recorded.

He listened, as usual, with deep and critical attention.
