"Well, I can't tell you that exactly, but I can put you on his track. It's worth, I should say,"--he deliberated, and looked at me covertly to decide what he would be likely to screw out of me--"not less than half a crown."

"I will give you that if you keep nothing back."

"All right. Where's the coin?"

"No, my friend," I said, "I'll have the goods before I pay for them."

"You're a sharp old file, but I'm out of work; It's capital and labor, and we know who's the grinder. Here was I, at six this morning, looking for work and not getting it. The doctor's shop shut, it's not the likes of him that catches worms. Back I come home at a quarter past seven, and there's a telegraph boy banging at the doctor's door. I help him bang, and out comes the doctor, doing up his buttons; takes the telegram, reads it, turns red and white, rushes into the house, rushes out in a brace of shakes, and scuds off. 'What's up?' thinks I, and off I scuds after him; he's too excited to notice. At St. George's Hospital, walking up and down in a fume, and looking as if he'd knock everything and everybody into a cocked hat if he had his way, there's a gentleman waiting for him, and a four-wheeler, with trunks atop, waiting for both of 'em. They have a hurried talk; I'm not near enough to hear what passes, but I get up to the cab as they step in. 'Charing Cross Station,' cries the gentleman to cabby. 'Break your horse's neck if you like; if I don't catch the Continental train I'll break yours.' Off goes the cab, and then, what do you think? off goes another cab that I hadn't noticed, after the first. I've got no money to pay for cabs, but having nothing better to do, and looking upon the move as a rum sort of move, I foots it to the station, and gets there at five minutes to eight. There they are, Dr. Cooper and his gentleman friend, as busy as bees, and there's the bell ringing and porters shouting, and everything hurry scurry. Away they go through the gate, and off goes the train; and if all that aint worth half a dollar I'd like to know what is."

"You shall have the money," I said; "are you sure they both went away in the train?"

"I'm sure they didn't comeback. I asked one of the porters what train that was. 'Train for Paris,' he said."

"Did you see the man who went after them in the second cab?"

"Never caught sight of him in the cab or out of it."

"But you saw the gentleman who met Dr. Cooper at the hospital."
