"He's about the villanousest I ever set eyes on," answered Mr. Tibbles.
"Well, Sawney, it's a bad job, certainly; but I've no doubt you've done your best."
"Yes, I have done my best," the assistant answered, rather indignantly: "and considerin' the deal of confidence you honoured me with about this here cove, I don't see as I could have done hanythink more."
"Then the best thing you can do is to keep watch here for the starting of the up-trains, while I go and keep my eye upon the station at the other side of the water," said Mr. Carter, "This journey to Hull may have been just a dodge to throw us off the scent, and our man may try and double upon us by going back to London. You'll keep all safe here, Sawney, while I go to the other side of the compass."
Mr. Carter engaged a fly, and made his way to a pier at the end of the town, whence a boat took him across the Humber to a station on the Lincolnshire side of the river.
Here he ascertained all particulars about the starting of the trains for London, and here he kept watch while two or three trains started. Then, as there was an interval of some hours before the starting of another, he re-crossed the water, and set to work to look for his man.
First he loitered about the quays a little, taking stock of the idle vessels, the big steamers that went to London, Antwerp, Rotterdam, and Hamburg—the little steamers that went short voyages up or down the river, and carried troops of Sunday idlers to breezy little villages beside the sea. He found out all about these boats, their destination, and the hours and days on which they were to start, and made himself more familiar with the water-traffic of the place in half an hour than another man could have done in a day. He also made acquaintance with the vessel that was to sail for Copenhagen—a black sulky-looking boat, christened very appropriately the Crow, with a black sulky-looking captain, who was lying on a heap of tarpaulin on the deck, smoking a pipe in his sleep. Mr. Carter stood looking over the quay and contemplating this man for some moments with a thoughtful stare.
"He looks a bad 'un," the detective muttered, as he walked away; "Sawney was right enough there."
He went into the town, and walked about, looking at the jewellers' shops with his accustomed rapid glance—a glance so furtive that it escaped observation—so full of sharp scrutiny that it took in every detail of the object looked at. Mr. Carter looked at the jewellers till he came to one whose proprietor blended the trade of money-lending with his more aristocratic commerce. Here Mr. Carter stopped, and entered by the little alley, within whose sombre shadows the citizens of Hull were wont to skulk, ashamed of the errand that betrayed their impecuniosity. Mr. Carter visited three pawnbrokers, and wasted a good deal of time before he made any discovery likely to be of use to him; but at the third pawnbroker's he found himself on the right track. His manner with these gentlemen was very simple.
"I'm a detective officer," he said, "from Scotland Yard, and I have a warrant for the apprehension of a man who's supposed to be hiding in Hull. He's known to have a quantity of unset diamonds in his possession—they're not stolen, mind you, so you needn't be frightened on that score. I want to know if such a person has been to you to-day?"
