T. B. did not answer immediately. He walked to the window and looked out. The little crowd which had been attracted by the shots and arrival of the police ambulance had melted away. The mist which had threatened all the evening had rolled into the square and the street lamps showed yellow through the dingy haze.
"I think," he said, "that I have at last got on the track of Montague Fallock."
Mr. Farrington looked at him with open mouth.
"You don't mean that?" he asked incredulously.
T. B. inclined his head.
"The open door below – the visitor?" jerked the stout man, "you don't think Montague Fallock was in the house to-night?"
T. B. nodded again, and there was a moment's silence.
"He has been blackmailing me," said Mr. Farrington, thoughtfully, "but I don't think – "
The detective turned up his coat collar preparatory to leaving.
"I have a rather unpleasant job," he said. "I shall have to search those unfortunate men."
Mr. Farrington shivered. "Beastly," he said, huskily.
T. B. glanced round the beautiful apartment with its silver fittings, its soft lights and costly panellings. A rich, warm fire burnt in an oxidized steel grate. The floor was a patchwork of Persian rugs, and a few pictures which adorned the walls must have been worth a fortune.
On the desk there was a big photograph in a plain silver frame – the photograph of a handsome woman in the prime of life.
"Pardon me," said T. B., and crossed to the picture, "this is – "
"Lady Constance Dex," said the other, shortly – "a great friend of mine and my ward's."
"Is she in town?"
Mr. Farrington shook his head.
"She is at Great Bradley," he said; "her brother is the rector there."
"Great Bradley?"
T. B.'s frown showed an effort to recollect something.
"Isn't that the locality which contains the Secret House?"
"I've heard something about the place," said Mr. Farrington with a little smile.
"C. D.," said the detective, making for the door.
"What?"
"Lady Constance Dex's initials, I mean," said T. B.
"Yes – why?"
"Those are the initials on the gold scent bottle, that is all," said the detective. "Good night."
He left Mr. Farrington biting his finger nails – a habit he fell into when he was seriously perturbed.
CHAPTER III
T. B. Smith sat alone in his office in Scotland Yard. Outside, the Embankment, the river, even the bulk of the Houses of Parliament were blotted out by the dense fog. For two days London had lain under the pall, and if the weather experts might be relied upon, yet another two days of fog was to be expected.
The cheery room, with its polished oak panelling and the chaste elegance of its electroliers, offered every inducement to a lover of comfort to linger. The fire glowed bright and red in the tiled fireplace, a silver clock on the mantelpiece ticked musically, and at his hand was a white-covered tray with a tiny silver teapot, and the paraphernalia necessary for preparing his meal – that strange tea-supper which was one of T. B. Smith's eccentricities.
He glanced at the clock; the hands pointed to twenty-five minutes past one.
He pressed a little button let into the side of the desk, and a few seconds later there was a gentle tap at the door, and a helmetless constable appeared.
"Go to the record room and get me" – he consulted a slip of paper on the desk – "Number G 7941."
The man withdrew noiselessly, and T. B. Smith poured out a cup of tea for himself.
There was a thoughtful line on his broad forehead, a look of unaccustomed worry on the handsome face, tanned with the suns of Southern France. He had come back from his holiday to a task which required the genius of a superman. He had to establish the identity of the greatest swindler of modern times, Montague Fallock. And now another reason existed for his search. To Montague Fallock, or his agent, must be ascribed the death of two men found in Brakely Square the night before.
No man had seen Montague; there was no photograph to assist the army of detectives who were seeking him. His agents had been arrested and interrogated, but they were but the agents of agents. The man himself was invisible. He stood behind a steel network of banks and lawyers and anonymities, unreachable.
The constable returned, bearing under his arm a little black leather envelope, and, depositing it on the desk of the Assistant Commissioner, withdrew.
T. B. opened the envelope and removed three neat packages tied with red tape. He unfastened one of these and laid three cards before him. They were three photographic enlargements of a finger print. It did not need the eye of an expert to see they were of the same finger, though it was obvious that they had been made under different circumstances.
T. B. compared them with a smaller photograph he had taken from his pocket. Yes, there was no doubt about it. The four pictures, secured by a delicate process from the almost invisible print on the latest letter of the blackmailer, proved beyond any doubt the identity of Lady Dex's correspondent.
He rang the bell again and the constable appeared in the doorway.
"Is Mr. Ela in his office?"
"Yes, sir. He's been taking information about that Dock case."
"Dock case? Oh yes, I remember; two men were caught rifling the Customs store; they shot a dock constable and got away."
"They both got away, sir," said the man, "but one was shot by the constable's mate; they found his blood on the pavement outside where their motor-car was waiting."
T. B. nodded.
"Ask Mr. Ela to come in when he is through," he said.
Mr. Ela was evidently "through," for almost immediately after the message had gone, the long, melancholy face of the superintendent appeared in the doorway.
"Come in, Ela," smiled T. B.; "tell me all your troubles."
"My main trouble," replied Ela, as he sank wearily into the padded chair, "is to induce eyewitnesses to agree as to details; there is absolutely no clue as to the identity of the robbers, and nearly murderers. The number of the car was a spurious one, and was not traced beyond Limehouse. I am up against a blank wall. The only fact I have to go upon is the very certain fact that one of the robbers was either wounded or killed and carried to the car by his friend, and that his body will have to turn up somewhere or other – then we may have something to go on."
"If it should prove to be that of my friend Montague Fallock," said T. B. humorously, "I shall be greatly relieved. What were your thieves after – bullion?"
"Hardly! No, they seem to be fairly prosaic pilferers. They engaged in going through a few trunks – part of the personal baggage of the Mandavia which arrived from Coast ports on the day previous. The baggage was just heavy truck; the sort of thing that a passenger leaves in the docks for a day or two till he has arranged for their carriage. The trunks disturbed, included one of the First Secretary to a High Commissioner in Congoland, a dress basket of a Mrs. Somebody-or-other whose name I forget – she is the wife of a Commissioner – and a small box belonging to Dr. Goldworthy, who has just come back from the Congo where he has been investigating sleeping sickness."
"Doesn't sound thrilling," said T. B. thoughtfully; "but why do swagger criminals come in their motor-cars with their pistols and masks – they were masked if I remember the printed account aright?" Ela nodded. "Why do they come on so prosaic an errand?"
"Tell me," said Ela, laconically, then, "What is your trouble?"
"Montague," said the other, with a grim smile, "Montague
