'Get, from the chief of police if necessary, the name of the up-town hotel where young Trent was last seen.'

'And then?' she urged, in a prompt, imperious manner quite new in my acquaintance with her.

'Obtain a description of him from some of the people there, and learn all that can be learned about him.'

'And what next?' she urged still.

'Next, I would seek among the houses within two or three blocks from the north entrance for the rooms which he engaged, and which are perhaps still held for him.'

'Mr. Masters, can you do this for me?' She was sitting erect before me, the very incarnation of repressed activity, and I knew, as well as if she had said it, that she would never permit my refusal to weaken the determination just taking shape in her mind to do for Hilda O'Neil what she could not have done for herself, and to do it boldly, promptly, openly. She saw my hesitation, and went on hurriedly:

'I know how busy you must be, how much I am asking, but you have undertaken to follow up that brunette and find out the reason for her interest in me, and surely this is far, far more important--a man's life, the happiness of a family, my friend's happiness at stake, perhaps; for I am sure that no common cause, nothing but danger, illness, or death, could keep Gerald Trent from communicating with his parents and his promised wife. Drop the brunette and all connected with her, Mr. Masters, and give such time as you would have given to my affairs, and more if possible, to this search, I beg of you. At least, promise me that you will conduct the search, and employ as many helpers as you need. I'll give you carte-blanche. Deal with me as you would with a man, and if I can aid in any other way than with my purse, let me do it.'

As she paused, with her eyes eagerly fixed upon my face, the sweet Quakeress leaned toward me, and put out her white slender hand in earnest appeal.

'"Thy brother's keeper;" remember that a deed of mercy is beyond and above all works of vengeance. What is the capture of a criminal, of many of them, compared to the rescue, the saving, perchance, of an honest man's life? I beg of thee, consent, help us!'

There may be men who could have resisted that appeal. I could not, and did not. I did not throw my other responsibilities to the winds; I simply did not think of them at the moment, when I took the soft hand of the elder woman in my own, and, looking across at the younger, said:

'I will do my best, Miss Jenrys, and, that not one moment may be lost, tell me, can you describe young Trent?'

'Not very well, I fear.'

'And his picture? Your friend must have that?'

'Of course,' half smiling.

'Telegraph her to forward it to you at once. And has your friend at any time mentioned the hotel where young Trent would stop? Most of our Eastern visitors have a favourite stopping-place.'

'I know.' She had made a movement toward her desk, but paused and turned toward me. 'I think it is safe to say that the two families would share the same house. They did in visiting the summer resorts, always; and I know where Mr. O'Neil and Mr. Trent went when they attended the great convention in this city.' She named the place, and I promptly arose.

'I will go there at once; but you may as well give me the Trents'

address, and permit me the use of your name. If I am wrong I will telegraph from up-town for the name of his hotel.'

As I turned my face cityward that morning I was not only fully committed to the search for missing Gerald Trent, but I was determined to convert my friend and partner to the same undertaking.

And having now found time for sober, second thought, I had also determined not to relinquish my search for the little brunette and her secret, nor for Messrs. Bob Delbras and company. Had I not carte-blanche?

As I left the house, intent upon my new errand, I was not surprised to see approaching it, almost at the door, in fact, Monsieur Voisin. We exchanged greetings at the entrance, and I had walked some distance before it occurred to me to wonder how it came about that Monsieur Voisin, whom I had last seen at the bootblack's stand, two blocks north and east, happened to be approaching Miss Jenrys' residence from the south.

CHAPTER XV.

THE KING OF CONFIDENCE MEN.

I found a number of people at the big up-town hotel who could tell me a little of Gerald Trent, as he appeared to them after a few days'

acquaintance; and these were unanimous in saying and believing that young Trent was not absent by his own will.

'It's a case of foul play, I'm sure of it,' declared the clerk, to whom I had represented myself as 'acting for one of Mr. Trent's friends.' 'Cowles saw him at the viaduct, he told me, just before he left; that was five days ago now, and Trent was then going down to secure those rooms and see that they were put in order. He went by the Suburban, because he wanted to go over to the avenues, and Cowles went down by the Whaleback.'

There was no more to be learned up-town. Gerald Trent had been last seen at the viaduct at the foot of Van Buren Street, where the 'cattle cars,' the 'Suburban,' and numerous boats left the Lake Front and the wharf beyond _en route_ for the Fair City. This was at ten o'clock a.m., or near it.

I went back to the Fair City, as Trent had last gone, upon the Suburban train; and before noon had begun an exploration, in the vicinity of the north entrance, for the rooms engaged by him.

Bounding the Fair City on the west was the street known as Stony Island Avenue, and after a short survey of such near portions of this street as I had not seen, I satisfied myself that young Trent would not have selected it as a place of abode for his lady mother, his sister, and his sweetheart. One block westward, running south from Fifty-seventh, was a short street called Rosalie Court, and after exploring this I pushed on to Washington Avenue, and then to Madison, running respectively one and two blocks parallel with Rosalie Court.

Something impelled me to pa.s.s by Washington Avenue, upon which Miss Jenrys and her aunt were lodged, and to explore the farther avenue first.

'If the rooms are within two or three blocks of the north entrance,' I said to myself, 'and if they are upon this street, I shall find them within one block north or south from this corner,' meaning Fifty-seventh Street, and I turned southward and began my search in earnest.

Not long since this part of the city had been a beautiful suburb, and the pretty cottages and more stately villas were, for the most part, isolated in the midst of their own grounds. Every other house it seemed, and some of the most pretentious, bore upon paling, piazza, or door-post the legend 'Rooms to Let,' and I applied and entered at a number of handsome and home-like portals, first upon the east side and then upon the west, crossing at Fifty-eighth Street to turn my face northward.

At Fifty-seventh I paused. 'It is something more than two blocks from the Fair entrance to this point,' I mused, 'and therefore I ought to go but one block in this direction.' But when I had traversed the block to Fifty-sixth Street, with no success, I crossed the street and went on, saying, 'It's easy for a stranger to be mistaken in a matter of distance.' At the north end of this square stood a large old-fashioned mansion, of a decidedly Southern type. It stood upon terraced grounds, and was a dignified reminder of better days, with its stained and time-roughened stuccos, and the worn paint about the ornate cornices. 'Rooms to Let' was the sign upon a tree-trunk, and after some doubt and hesitation, I went up the terraced steps, crossed the lawn, and rang a bell much newer than its surroundings.

Once admitted to the wide, inviting hall, with its glimpse of cheerful dining-room beyond, and a large cool parlour opening at the side, I felt that Trent might well have sought quarters in this roomy, airy house; and when the 'lady of the house,' a woman small, elderly, delicate, and refined, appeared before me, I put my question hopefully.

'Madam, have you among the inmates of your house a Mr. Gerald Trent?'

I saw by her sudden change of countenance that the name was not strange to her, and was not surprised when she informed me that a Mr.

Trent had engaged her best suite of rooms for himself and four others; that he had called upon her on the Monday previous, paid her an advance upon the rooms, and informed her that his friends would arrive in three days, if not sooner.

'They should have been here,' she concluded, 'the day before yesterday, but they have not appeared, and we have had no word from them. It is very inconvenient for me. Of course, the rooms are secured until Monday, but I have no means of knowing if they will come then; or when I may consider them at my disposal.'

It was evident she had not seen the papers, and I at once put the notice in her hand, and told her the nature of my business.

There seemed but one opinion of Gerald Trent. When she had read the paper and heard my statement, she said, at once, what the inmates of the hotel had said before her:

'Something has happened him. He never went away like this of his own accord. I never saw a more simple and sincere young man.' And then, as if by an afterthought, 'He had too much money about him; he was too well dressed, and--I don't think he was of a suspicious nature.'

I learned from her very little to help my further search. Trent had met none of the guests of the house upon either of his visits there.

In reply to a question, she had said:

'He seemed in the best of spirits when he paid the advance money and went away; and he said that he meant to spend the day in the Plaisance. I remember that he laughed when he said this, and added something to the effect that he wanted to decide, before the ladies came, where it would pay to go on the Plaisance, and what were the things they would not care for. He had a rather frank and boyish way of expressing himself.'

'And you think he went from here to the Fair?'

'I believe he went from here to Midway Plaisance. There is an entrance on this street, three blocks south, and I walked to the door with him and pointed the way to it.'

And this was all. Of course I took from her lips, as from the people up-town, a minute description of Trent's dress and appearance on the day of his disappearance, and then I went back to the Fair by the Midway gate, and wished impatiently for the time to come when I should meet Brainerd and consult with him. This I knew would not be until a late hour, and as I lounged down the Plaisance I began to look about for the handsome guard, in whom I had taken a decided interest.

I found him easily--as erect, soldierly, attentive to duty as usual--and we spent the greater part of two hours chatting, while we paced up and down Midway. He was a bright talker, and he entertained me with a number of amusing incidents, graphically related, and ill.u.s.trative of the life of the Plaisance.

During the two hours, however, I broke the monotony of a continuous tramp by an excursion, now on one side and then on the other; now to see the gla.s.s-blowers; now the submarine exhibit; and, lastly, to the Irish village that cl.u.s.tered about Blarney Castle.

It was on my return from this that, as I approached him, I saw, with some surprise, that he was in earnest conversation with a woman, and as I came nearer and he shifted his position slightly, I saw that the woman was none other than that _ignis fatuus_ the brunette. Her back was toward me, and she was squarely facing him, so that, as I came nearer and directly toward them, I caught his eye, and, nodding with a gesture which I think he understood, I turned away and watched the manoeuvres of 'the little mystery,' as Brainerd so often called the brunette, wondering if this unknown guard was also to be enmeshed in the plot she seemed to be weaving. And then there flashed into my mind that first meeting with the guard, and his avowed acquaintance with Miss Jenrys. Was this interview in any way connected with or concerning her?

The brunette had not seen me; of that I was quite a.s.sured, and even so I had small fear of recognition, for while I had not, on the occasion of our two meetings face to face, worn any disguise, I was confident that the widely different garments worn on the two occasions, together with my ability to elongate, twist, and change my features, and to alter the pitch of my voice, was masquerade sufficient. But I did not desire to become known to this anomalous personage, and I lingered here and there, within sight and at a safe distance, until I saw her nod airily and trip away, flinging a smile over her shoulder.
