only the place where a letter will find him, or where he goes to meet his pals, and perhaps do a little quiet betting in the landlord's back parlour.' 'That will be enough for us, to begin with at any rate.' 'Of course, the private address is only a matter of a day or two longer,' Mr. Slippen went on. 'I have only to send that boy of mine up to the place, and the first time the fellow goes there he will follow him, if it is all over London, till he traces him to the place where he lives. If, as he said, he is going to give up attending the races for the present, he may not go there for a day or two. But he is sure to do so sooner or later for letters.' 'Thank you. It would be as well to know where he lives, but at any rate when we have what we may call his business address we shall have time to talk over our next move.' 'Yes, that is where the real difficulty will begin, Captain Hampton. I expect you have got to deal with a deep one, and I own that at present I do not see my way at all clear before me.' CHAPTER V That evening Mr. Slippen's boy presented himself at Captain Hampton's lodgings with a note. It contained only the words 'Dear sir,--Our man uses the "White Horse," Frogmore Street, Islington. I await your instructions before moving further in the matter.' 'Well, youngster, what is your name?' Captain Hampton asked, as he put the note on the table beside him. 'Jacob Wrigley,' the lad replied promptly. 'Here is half-a-crown for yourself, Jacob.' 'Thank you, sir,' the boy said, as he took it up with a duck of the head and slipped it into his pocket. 'Your office hours seem to be long, Jacob; that is, if you have been there since I saw you this morning.' 'No, sir, I ain't a-been there since one o'clock, not till an hour ago. I have been down at Greenwich, keeping my eye on a party there. I got done there at six o'clock, and as the governor had said "Come round and tell me what you have found out, I shall be in up to nine o'clock," round I went in course. The governor and me don't have no regular hours. Some chaps wouldn't like that, but it doesn't matter to me, 'cause I sleeps there.' 'Sleep where, Jacob?' 'In where you see me. The things is stowed away in that cupboard in the corner, and I get on first-rate. It is a good place, especially in winter. I lays the blankits down in front of the fire, and keeps it going all night sometimes.' 'But haven't you got any place of your own to go to, Jacob?'
