"Yes, I have done my best," the a.s.sistant 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 compa.s.s."

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 p.a.w.nbrokers, and wasted a good deal of time before he made any discovery likely to be of use to him; but at the third p.a.w.nbroker'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 quant.i.ty 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?"

"The diamonds are all right?" asked the p.a.w.nbroker, rather nervously.

"Quite right. I see the man has been here. I don't want to know anything about the jewels: they're his own, and it's not them we're after. I want to know about _him_. He's been here, I see--the question is, what time?"

"Not above half an hour ago. A man in a dark blue coat with a fur collar----"

"Yes; a man that walks lame."

The p.a.w.nbroker shook his head.

"I didn't see that he was lame," he said.

"Ah, you didn't notice; or he might hide it just while he was in here.

He sat down, I suppose?"

"Yes; he was sitting all the time."

"Of course. Thank you; that'll do."

With this Mr. Carter departed, much to the relief of the money-lender.

The detective looked at his watch, and found that it was half-past one.

At half-past three there was a London train to start from the station on the Lincolnshire side of the water. The other station was safe so long as Mr. Tibbles remained on the watch there; so for two hours Mr. Carter was free to look about him. He went down to the quay, and ascertained that no boat had crossed to the Lincolnshire side of the river within the last hour. Joseph Wilmot was therefore safe on the Yorkshire side; but if so, where was he? A man wearing a dark blue coat lined with sable, and walking very lame, must be a conspicuous object wherever he went; and yet Mr. Carter, with all the aid of his experience in the detective line, could find no clue to the whereabouts of the man he wanted. He spent an hour and a half in walking about the streets, prying into all manner of dingy little bars and tap-rooms, in narrow back streets and down by the water-side; and then was fain to go across to Lincolnshire once more, and watch the departure of the train.

Before crossing the river to do this, he had taken stock of the _Crow_ and her master, and had seen the captain lying in exactly the same att.i.tude as before, smoking a dirty black pipe in hie sleep.

Mr. Carter made a furtive inspection of every creature who went by the up-train, and saw that conveyance safely off before he turned to leave the station. After doing this he lost no time in re-crossing the water again, and landed on the Yorkshire side of the Humber as the clocks of Hull were striking four.

He was getting tired by this time, but he was not tired of his work. He was accustomed to spending his days very much in this manner; he was used to taking his sleep in railway carriages, and his meals at unusual hours, whenever and wherever he could get time to take his food. He was getting what ha called "peckish" now, and was just going to the coffee-room of the Victoria Hotel with the intention of ordering a steak and a gla.s.s of brandy-and-water--Mr. Carter never took beer, which is a sleepy beverage, inimical to that perpetual clearness of intellect necessary to a detective--when he changed his mind, and walked back to the edge of the quay, to prowl along once more with his hands in his pockets, looking at the vessels, and to take another inspection of the deck and captain of the _Crow_.

"I shouldn't wonder if my gentleman's gone and hidden himself down below the hatchway of that boat," he thought, as he walked slowly along the quay-side. "I've half a mind to go on board and overhaul her."

CHAPTER XLIV.

CHASING THE "CROW."

Mr. Carter was so familiar with the spot alongside which the _Crow_ lay at anchor, that he made straight for that part of the quay and looked down over the side, fully expecting to see the dirty captain still lying on the tarpaulin, smoking his dirty pipe.

But, to his amazement, he saw a strange vessel where he expected to see the _Crow_, and in answer to his eager inquiries amongst the idlers on the quay, and the other idlers on the boats, he was told that the _Crow_ had weighed anchor half an hour ago, and was over yonder.

The men pointed to a dingy speck out seaward as they gave Mr. Carter this information--a speck which they a.s.sured him was neither more nor less than the _Crow_, bound for Copenhagen.

Mr. Carter asked whether she had been expected to sail so soon.

No, the men told him; she was not expected to have sailed till daybreak next morning, and there wasn't above two-thirds of her cargo aboard her yet.

The detective asked if this wasn't rather a queer proceeding.

Yes, the men said, it was queer; but the master of the _Crow_ was a queer chap altogether, and more than one absconding bankrupt had sailed for furrin parts in the _Crow_. One of the men opined that the master had got a swell cove on board to-day, inasmuch as he had seen such a one hanging about the quay-side ten minutes or so before the _Crow_ sailed.

"Who'll catch her?" cried Mr. Carter; "which of you will catch her for a couple of sovereigns?"

The men shook their heads. The _Crow_ had got too much of a start, they said, considering that the wind was in her favour.

"But there's a chance that the wind may change after dark," returned the detective. "Come, my men, don't hang back. Who'll catch the _Crow_ yonder for a fiver, come? Who'll catch her for a fi'-pound note?"

"I will," cried a burly young fellow in a scarlet guernsey, and shiny boots that came nearly to his waist; "me and my mate will do it, won't us, Jim?"

Jim was another burly young fellow in a blue guernsey, a fisherman, part owner of a little bit of a smack with a brown mainsail. The two stalwart young fishermen ran along the quay, and one of them dropped down into a boat that was chained to an angle in the quay-side, where there was a flight of slimy stone steps leading down to the water. The other young man ran off to get some of the boat's tackle and a couple of s.h.a.ggy overcoats.

"We'd best take something to eat and drink, sir," the young man said, as he came running back with these things; "we may be out all night, if we try to catch yon vessel."

Mr. Carter gave the man a sovereign, and told him to get what he thought proper.

"You'd best have something to cover you besides what you've got on, sir," the fisherman said; "you'll find it rare and cold on 't water after dark."

Mr. Carter a.s.sented to this proposition, and hurried off to buy himself a railway rug; he had left his own at the railway station in Sawney Tom's custody. He bought one at a shop near the quay, and was back to the steps in ten minutes.

The fisherman in the blue guernsey was in the boat, which was a stout-built craft in her way. The fisherman in the scarlet guernsey made his appearance in less than five minutes, carrying a great stone bottle, with a tin drinking-cup tied to the neck of it, and a rush basket filled with some kind of provision. The stone bottle and the basket were speedily stowed away in the bottom of the boat, and Mr. Carter was invited to descend and take the seat pointed out to him.

"Can you steer, sir?" one of the men asked.

Yes, Mr. Carter was able to steer. There was very little that he had not learned more or less in twenty years' knocking about the world.

He took the rudder when they had pushed out into the open water, the two young men dipped their oars, and away the boat shot out towards that seaward horizon on which only the keenest eyes could discover the black speck that represented the _Crow_.

"If it should be a sell, after all," thought Mr. Carter; "and yet that's not likely. If he wanted to double on me and get back to London, he'd have gone by one of the trains we've watched; if he wanted to lie-by and hide himself in the town, he wouldn't have disposed of any of his diamonds yet awhile--and then, on the other hand, why should the _Crow_ have sailed before she'd got the whole of her cargo on board? Anyhow, I think I have been wise to risk it, and follow the _Crow_. If this is a wild-goose chase, I've been in wilder than this before to-day, and have caught my man."
