Yet, how was I to have guessed her intent concerning him?

Knowing her pursuit of Miss Jenrys, I felt so sure that she was only using him as a means for obtaining information about that young lady, and that this interview was only the beginning of what was meant to become an acquaintance more or less confidential.

As a result of my reticence, the young fellow had barely escaped with his life; even now, so the doctor said, fever or inflammation might put it in jeopardy.

Well, it was not my only blunder, I thought, looking back, with a grim smile, to my first absurd exploit. But I would try very hard to make it my last; at least, where 'the gang,' as Dave was wont to call Delbras and Company, was concerned. And when thinking of 'the gang,' I could not but note how both Dave and myself had reversed our first order in naming them, and now spoke, invariably, not of 'Greenback Bob and the rest,' but of 'Delbras and Company.' Somehow, Delbras seemed to have taken the foremost place in our thoughts, as I fully believed he was foremost in all the plots, plans and undertakings of the mysterious and elusive three. And yet he was the one out of the gang against whom we had no actual case.

We could see the hand of Greenback Bob in the counterfeit two-dollar greenbacks which had started into circulation so briskly, and then so suddenly dropped out of sight. And his work was also visible in that attack upon the guard; for who, according to the police records, could handle a 'slung-shot' as could Bob? And that the guard's wound was the work of a sling, we—the surgeon and myself—quite believed.

As for the brunette, we might begin with her little confidence game, in which she did not secure Miss Jenrys' bag; charge her with the sale of the stolen emerald, and bring home to her the loss of the 'dew-drops' and other contents of the chamois-bag lost in her flight across Wooded Island—when we found her again.

But Delbras! We might believe him to be the originator of, and prime mover in, the Lausch diamond robbery, but the only shadow of corroboration was our belief—based upon the fact of Dave's having seen the three together—that they were 'partners,' and that Delbras was credited with being an expert diamond thief. Not a promising outlook, I sometimes said to Dave, in my moments of discouragement, which my practical friend declared were somehow always synonymous with my moments of hunger.

But to return to our guard and his interests. During the fifteen minutes kindly granted by the doctor, and which somehow ran into half an hour before he came and ordered me away, I contrived to establish between myself and the invalid a very sufficient understanding, and I left him feeling that, so far as lay in my power, he was warned against his enemies, and knew them, at least, as well as I did.

Upon one question, however, we differed. As I was about to take leave, I said: 'There is one thing that I foresee, and that is a renewal of your social relations with Miss Jenrys and a beginning of the same with her aunt. I can see reasons why it might be better—might simplify matters—if you kept up at least an outside appearance of coolness. You understand?'

'Yes.' He was silent for a little time, then: 'Will this be of actual use or help to you?'
