What a kaleidoscopic panorama! In taking my place I had not even noticed the direction in which I was moving. I had been seeing such a marvel of glimpses, domes, roofs, the lagoon in the distance, a flashing glimpse of the lake through glittering, airy turrets, trees, statues, flags--beauty and charm everywhere. I had taken a round-trip ticket, and I whirled on and on, until somehow I saw the great gla.s.s dome of the Horticultural Building, and a moment later a fleeting view of Midway recalled to my mind my own personality and interests. As I gazed at it, stretching away westward, a veritable Joseph's coat of a street, it was gone, and I saw the tall dome of Illinois, the Art Gallery in the distance, with the lagoon again gleaming through trees, to be lost again, while roofs, windows, vistas of streets surrounded me, and I could peep in at the windows we were pa.s.sing; and then I heard the cry of the guard, and noted the name as we slacked speed at Mount Vernon Station, almost upon the roof of the Old Virginia Building. I peered out as we drew up to this station in the air, and drew back a little as a second train, moving in the opposite direction, dashed by. I am in the rear car, and as we move away from Mount Vernon, suddenly I have a vision of someone who must have flung himself from the forward car at the last moment, and who is running along the platform, and in the direction of the pa.s.sing train, in breathless haste, his head bare, his hat clutched in his swinging hand.

It is Dave Brainerd, and as we tear around a curve and he is lost to my sight, I am brought back to thoughts of business. Dave has evidently 'struck a trail.' Wondering much, I stop at the north loop, and standing with the Government Building to my right and the Fisheries with its curving colonnades on my left, I gaze off upon the blue and shining waters of the lake, and realize fully for the first time the awful incongruity between all this stateliness and beauty and our mission in its midst--a criminal hunt!

CHAPTER VII.

'IT WAS GREENBACK BOB.'

Our chief had arranged for us, and in advance of our arrival, that our letters should be received at the bureau, where a desk was always at our disposal; and a little before four o'clock I dropped in once more to look for letters and ask if Dave had made a second appearance. The letters were in waiting for both of us, but there was no news of Dave, and, stowing the letters in my pocket, I sought once more the Court of Honour; seating myself near the great MacMonnies Fountain, in the shade of the Administration Building, where Dave could not fail to find me, to read my letters and wait for him.

I was in no haste, with that magnificent court spread out before me, and the blue dancing waves of Lake Michigan in the distance, Nature's background for the great Peristyle, surmounted by that novel and beautiful Columbus quadriga, in itself a work of art such as is seldom seen, and with golden Justice, dominant and serene, commanding and overlooking all.

Forgetting my letters, I let my eyes wander slowly from point to point of beauty, letting the moments pa.s.s unheeded.

'Fine figure of a woman, eh?'

I started, and came suddenly down to earth, at the sound of one of my friend's characteristic speeches. He was standing beside me, as imperturbable of countenance as usual, but looking somewhat blown; and he dropped upon the bench, and stretched his legs, and pulled off his hat, like a weary man who means to enjoy a little well-earned rest.

I knew him too well to display any curiosity, and I merely sorted out from the bundle of letters still unopened in my hand those bearing his name, and laid them upon his knee, and with merely a nod and smile, by way of greeting, addressed myself to my own.

The first was a brief business doc.u.ment; the next a schoolboy's letter, short, of course, from a young brother, my sole living tie and charge. The third was from our chief, and I saw, upon opening it, that it was addressed, within, to both of us.

'Dave,' I ventured, 'may I interrupt?'

'You can't,' he replied. 'I've done. They're of no consequence,' and he thrust the two missives I had given him into his loose side-pocket.

'Blaze away, boy.'

The letter was not long, and, after some minor instructions and some suggestions, came this pa.s.sage:

'"I wonder if either of you remembers the case of the Englishman who wrote us at much length some six months ago concerning his son, 'lost or missing'--we did not succeed in finding him in New York----"'

'And small wonder,' chuckled Dave, whose memory was a storehouse. 'We hadn't even the skeleton of a description.'

'"In New York, you remember,"' I read on, '"and it has seemed to me that you may as well look out for him in your intervals of leisure, if there are such."'

'Old man's growing sarcastic,' grumbled my friend.

'"It's a good thing, if successful,"' I continued; '"and the Fair is the best place in the world for a 'hide out.' If the young fellow's above-ground I'll wager something he's in Chicago now; that is, if he really did come to America a year ago, as his fond father (?) writes.

I enclose for your further information his letter; and I would be proud of the fact if you two fellows could unearth him at the Columbian City. I give you _carte blanche_ for the case."'

'Umph! That means roll up your sleeves and go in.'

I took up the copy of the Englishman's letter. 'Shall I read it?' I asked, 'or is it----'

'Don't say "engraven on your memory,"' implored Dave. 'Yes--go ahead.'

'"DUNDALK HOUSE, '"_January 3, 1893_.

'"MESSRS. ----.

'"GENTLEMEN,--On November 6th, in the year 1892, Carroll L.

Rae, Esq., of Dundalk House, left his home, ostensibly for a few days in London. He was never seen again at Dundalk, and we have been accurately informed that he sailed for America in that same month. Being of age, he drew from his bankers while in London one thousand pounds, the full amount deposited to his credit; since that time no trace of him has been found.

'"Carroll L. Rae is twenty-six years of age, and tall, lacking one-half inch of being six feet in height. He is slender, broad-shouldered, upright; fair skin, blue eyes, brown hair; features regular and refined; hair worn very short, but inclined to curl close to skull; strong in athletic sports; a graduate of Queen's College; has small, aristocratic feet and hands; a skilled horseman; sings a fine and unusually high tenor; has a singularly strong control over all animals. We have no portrait of him since childhood.

Has strong leaning toward military life and somewhat literary tendencies. Am prepared to send blank cheque for the payment of expenses of thorough search, and add as reward when found two thousand pounds. Address all correspondence to

'"SIR HUGO RAE, '"Dundalk House, Egham, '"Surrey."'

'Umph!' broke out Brainerd, when I had read the last word. 'Typical old English paterfamilias! Tyrannical, I'll be bound. I'll bet something the young fellow ran away from parental tyranny. How did the thing come out at the first attempt? I don't seem to recall it.'

'And for a good reason. You were in Canada, and I was occupied with that Rockville murder. I think they put Sturgis on the case. English himself, you know.'

'Yes--well?'

'Well, as nearly as I remember, Sturgis advertised, to begin, "something to his advantage," etc.'

'Of course!' contemptuously.

'This failed, and he made the tour of the hotels, swell places first, then going down in the scale, hunted the registers; haunted the places most affected by the English tourist; halted good-looking, or English-looking, blond young men until they turned on him. In fact, tried all the dodges--and failed.'

'Of course! It's one thing to find a person who has been hidden, and quite another to search for one who hides himself. What do you think has set the chief to looking this lost son up here, and through us?'

'Why, you know his ways--he seldom stops to explain; but I fancy he may have heard again from Sir Hugo Rae.'

I took up the two sheets, and was about to thrust them into their envelope, when Brainerd suddenly said:

'Hold on, boy! there's something written across the back of that copied letter.'

I turned it over and read the half-dozen lines written thereon:

'"Carroll Rae, if found, is to be told at once that his brother, Sir Hugo, is dead."'

'Oh!' e.j.a.c.u.l.a.t.ed Brainerd; 'so it's not his father. Well, that alters things. We may be able to find a Sir Carroll Rae, especially as he must have about exhausted that thousand pounds if he has been doing the States in true English style.'

'At any rate,' I added, 'it's on our books. I suppose one may keep an eye out for a swell young Englishman here as well as elsewhere. It's only one more face in the crowd.'

'And that reminds me,' said my friend. 'This business almost put it out of my head. I took a turn on that Intramural road this afternoon.'

'Yes?' I knew better than to interrupt at this point.

'And I saw, I am sure I saw--whom do you think?'

'Dave, that's like a woman! I'm surprised at you. You saw Delbras.'

'Wrong! I saw, I'm certain of it, Greenback Bob.'
