Hewitt followed the girl to the basement, apparently looking straight before him, but in reality taking in every detail of the place. The gas meter was in a very large lumber cupboard under the kitchen stairs. The girl opened the door and lit a candle. The meter stood on the floor, which was littered with hampers and boxes and odd sheets of brown paper. But a thing that at once arrested Hewitt’s attention was a garment of some sort of bright blue cloth, with large brass buttons, which was lying in a tumbled heap in a corner, and appeared to be the only thing in the place that was not covered with dust. Nevertheless, Hewitt took no apparent notice of it, but stooped down and solemnly tapped the meter three times with his pencil, and listened with great gravity, placing his ear to the top. Then he shook his head and tapped again. At length he said:
‘It’s a bit doubtful. I’ll just get you to light the gas in the kitchen a moment. Keep your hand to the burner, and when I call out shut it off at once; see?’
The girl turned and entered the kitchen, and Hewitt immediately seized the blue coat — for a coat it was. It had a dull red piping in the seams, and was of the swallowtail pattern — livery coat, in fact. He held it for a moment before him, examining its pattern and colour, and then rolled it up and flung it again into the corner.
‘Right!’ he called to the servant. ‘Shut off!’
The girl emerged from the kitchen as he left the cupboard.
‘Well,’ she asked, ‘are you satisfied now?’
‘Quite satisfied, thank you,’ Hewitt replied.
‘Is it all right?’ she continued, jerking her hand toward the cupboard.
‘Well, no, it isn’t; there’s something wrong there, and I’m glad I came. You can tell Mr Merston, if you like, that I expect his gas bill will be a good deal less next quarter.’ And there was a suspicion of a chuckle in Hewitt’s voice as he crossed the hall to leave. For a gas inspector is pleased when he finds at length what he has been searching for.
Things had fallen out better than Hewitt had dared to expect. He saw the key of the whole mystery in that blue coat; for it was the uniform coat of the hall porters at one of the banks that he had visited in the morning, though which one he could not for the moment remember. He entered the nearest post-office and despatched a telegram to Plummer, giving certain directions and asking the inspector to meet him; then he hailed the first available cab and hurried toward the City.
At Lombard Street he alighted, and looked in at the door of each bank till he came to Buller, Clayton, Ladds & Co.‘s. This was the bank he wanted. In the other banks the hall porters wore mulberry coats, brick-dust coats, brown coats, and what not, but here, behind the ladders and scaffold poles which obscured the entrance, he could see a man in a blue coat, with dull red piping and brass buttons. He sprang up the steps, pushed open the inner swing door, and finally satisfied himself by a closer view of the coat, to the wearer’s astonishment. Then he regained the pavement and walked the whole length of the bank premises in front, afterwards turning up the paved passage at the side, deep in thought. The bank had no windows or doors on the side next the court, and the two adjoining houses were old and supported in place by wooden shores. Both were empty, and a great board announced that tenders would be received in a month’s time for the purchase of the old materials of which they were constructed; also that some part of the site would be let on a long building lease.
Hewitt looked up at the grimy fronts of the old buildings. The windows were crusted thick with dirt — all except the bottom window of the house nearer the bank, which was fairly clean, and seemed to have been quite lately washed. The door, too, of this house was cleaner than that of the other, though the paint was worn. Hewitt reached and fingered a hook driven into the left-hand doorpost about six feet from the ground. It was new, and not at all rusted; also a tiny splinter had been displaced when the hook was driven in, and clean wood showed at the spot.
Having observed these things, Hewitt stepped back and read at the bottom of the big board the name, ‘Winsor & Weekes, Surveyors and Auctioneers, Abchurch Lane’. Then he stepped into Lombard Street.
Two hansoms pulled up near the post-office, and out of the first stepped Inspector Plummer and another man. This man and the two who alighted from the second hansom were unmistakably plain-clothes constables — their air, gait, and boots proclaimed it.
‘What’s all this?’ demanded Plummer, as Hewitt approached.
‘You’ll soon see, I think. But, first, have you put the watch on No. 197, Hackworth Road?’
‘Yes; nobody will get away from there alone.’
‘Very good. I am going into Abchurch Lane for a few minutes. Leave your men out here, but just go round into the court by Buller, Clayton & Ladds’s, and keep your eye on the first door on the left. I think we’ll find something soon. Did you get rid of Miss Shaw?’
‘No, she’s behind now, and Mrs Laker’s with her. They met in the Strand, and came after us in another cab. Rare fun, eh! They think we’re pretty green! It’s quite handy, too. So long as they keep behind me it saves all trouble of watching them.’ And Inspector Plummer chuckled and winked.
‘Very good. You don’t mind keeping your eye on that door, do you? I’ll be back very soon,’ and with that Hewitt turned off into Abchurch Lane.
At Winsor & Weekes’s information was not difficult to obtain. The houses were destined to come down very shortly, but a week or so ago an office and a cellar in one of them was let temporarily to a Mr Westley. He brought no references; indeed, as he paid a fortnight’s rent in advance, he was not asked for any, considering the circumstances of the case. He was opening a London branch for a large firm of cider merchants, he said, and just wanted a rough office and a cool cellar to store samples in for a few weeks till the permanent premises were ready. There was another key, and no doubt the premises might be entered if there were any special need for such a course. Martin Hewitt gave such excellent reasons that Winsor & Weekes’s managing clerk immediately produced the key and accompanied Hewitt to the spot.
‘I think you’d better have your men handy,’ Hewitt remarked to Plummer when they reached the door, and a whistle quickly brought the men over.
The key was inserted in the lock and turned, but the door would not open; the bolt was fastened at the bottom. Hewitt stooped and looked under the door.
‘It’s a drop bolt,’ he said. ‘Probably the man who left last let it fall loose, and then banged the door, so that it fell into its place. I must try my best with a wire or a piece of string.’
A wire was brought, and with some manoeuvring Hewitt contrived to pass it round the bolt, and lift it little by little, steadying it with the blade of a pocket-knife. When at length the bolt was raised out of the hole, the knife-blade was slipped under it, and the door swung open.
They entered. The door of the little office just inside stood open, but in the office there was nothing, except a board a couple of feet long in a corner. Hewitt stepped across and lifted this, turning it downward face toward Plummer. On it, in fresh white paint on a black ground, were painted the words
“BULLER, CLAYTON, LADDS & CO.,
TEMPORARY ENTRANCE.”
Hewitt turned to Winsor & Weekes’s clerk and asked, ‘The man who took this room called himself Westley, didn’t he?’
‘Yes.’
‘Youngish man, clean-shaven, and well-dressed?’
‘Yes, he was.’
‘I fancy,’ Hewitt said, turning to Plummer, ‘I fancy an old friend of yours is in this — Mr Sam Gunter.’
‘What, the “Hoxton Yob”?’
‘I think it’s possible he’s been Mr Westley for
