'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!' ejaculated 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.'

'Good!'

'He was dressed very swell--you might have mistaken him for one of the
board of directors; but it was Bob.'

'And you piped him home, of course?' I queried.

'Of course I didn't. He was going one way, and I the other, each on an
Intramural car.'

'Oh! and you were running to stop the car, and Bob, when I saw you at
Mount Vernon Station,' I said wickedly; 'did you overtake it?'

'I did--just.'

'And Bob?' eagerly.

'Well,' with a grin, 'I'm sorry to disappoint you, but when I jumped
on board, at the last moment, I found that Bob had got off while I got
on. In fact, I saw him going downstairs as I was borne away to
Fifty-seventh Street. There, boy, don't look so mournful; it's all in
the game. I couldn't find a trace of him; but we know he's here.'

I had decided on the night of my arrival, after pondering late the
adventure of the black bag, or, as I now described it to myself, Miss
Jenrys' bag, upon my course of action concerni
