shrilled a voice in French, "Am I to be robbed of——" and the rest was indistinguishable.
There was a policeman on point duty at the other side of the square. Mr. Farrington's fingers rubbed the glass with greater energy, and his anxious eyes looked left and right for the custodian of the law.
He crept down the stairs, opened the metal flap of the letter-box and listened. It was not difficult to hear all they said, though they had dropped their voices, for they stood at the foot of the steps.
"What is the use?" said one in French. "There is a reward large enough for two—but for him—my faith! there is money to be made, sufficient for twenty. It is unfortunate that we should meet on similar errands, but I swear to you I did not desire to betray you——" The voice sank.
Mr. Farrington chewed the butt of his cigar in the darkness of the hall and pieced together the jigsaw puzzle of this disjointed conversation. These men must be associates of Montague—Montague Fallock, who else?
Montague Fallock, the blackmailer for whom the police of Europe were searching, and individually and separately they had arranged to blackmail him—or betray him.
The fact that T. B. Smith also had a house in Brakely Square, and that T. B. Smith was an Assistant Commissioner of the police, and most anxious to meet Montague Fallock in the flesh, might supply reason enough to the logical Mr. Farrington for this conversation outside his respectable door.
"Yes, I tell you," said the second man, angrily, "that I have arranged to see M'sieur—you must trust me——"
"We go together," said the other, definitely, "I trust no man, least of all a confounded Neapolitan——"
Constable Habit had not heard the sound of quarrelling voices, as far as could be gathered from subsequent inquiry. His statement, now in the possession of T. B. Smith, distinctly says, "I heard nothing unusual."
But suddenly two shots rang out.
"Clack—clack!" they went, the unmistakable sound of an automatic pistol or pistols, then a police whistle shrieked, and P. C. Habit broke into a run in the direction of the sound, blowing his own whistle as he ran.
He arrived to find three men, two undoubtedly dead on the ground, and the third, Mr. Farrington's unpicturesque figure, standing shivering in the doorway of his house, a police whistle at his lips, and his grey velvet dressing-gown flapping in a chill eastern wind.
Ten minutes later T. B. Smith arrived on the scene from his house, to find a crowd of respectable size, half the bedroom windows of Brakely Square occupied by the morbid and the curious, and the police ambulance already on the spot.
"Dead, sir," reported the constable.
T. B. looked at the men on the ground. They were obviously foreigners. One was well, almost richly dressed; the other wore the shabby evening dress of a waiter, under the long ulster which covered him from neck to foot.
The men lay almost head to head. One flat on his face (he had been in this position when the constable found him, and had been restored to that position when the methodical P. C. Habit found that he was beyond human assistance) and the other huddled on his side.
The police kept the crowd at a distance whilst the head of the secret police (T. B. Smith's special department merited that description) made a careful examination. He found a pistol on the ground, and another under the figure of the huddled man, then as the police ambulance was backed to the pavement, he interviewed the shivering Mr. Farrington.
"If you will come upstairs," said that chilled millionaire, "I will tell you all I know."
T. B. sniffed the hall as he entered, but said nothing. He had his olfactory sense developed to an abnormal degree, but he was a tactful and a silent man.
He knew Mr. Farrington—who did not?—both as a new neighbour and as the possessor of great wealth.
"Your daughter——" he began.
"My ward," corrected Mr. Farrington, as he switched on all the lights of his sitting-room, "she is out—in fact she is staying the night with my friend Lady Constance Dex—do you know her?"
T. B. nodded.
"I can only give you the most meagre information," said Mr. Farrington. He was white and shaky, a natural state for a law-abiding man who had witnessed wilful murder. "I heard voices and went down to the door, thinking I would find a policeman—then I heard two shots almost simultaneously, and opened the door and found the two men as they were found by the policeman."
"What were they talking about?"
Mr. Farrington hesitated.
"I hope I am not going to be dragged into this case as a witness?" he asked, rather than asserted, but received no encouragement in the spoken hope from T. B. Smith.
"They were discussing that notorious man, Montague Fallock," said the millionaire; "one was threatening to betray him to the police."
"Yes," said T. B. It was one of those "yesses" which signified understanding and conviction.
Then suddenly he asked:
"Who was the third man?"
Mr. Farrington's face went from white to red, and to white again.
"The third man?" he stammered.
"I mean the man who shot those two," said T. B., "because if there is one thing more obvious than another it is that they were both killed by a third person. You see," he went on, "though they had pistols neither had been discharged—that was evident, because on each the safety catch was raised. Also the lamp-post near which they stood was chipped by a bullet which neither could have fired. I suggest, Mr. Farrington, that there was a third man present. Do you object to my searching your house?"
A little smile played across the face of the other.
"I haven't the slightest objection," he said. "Where will you start?"
"In the basement," said T. B.; "that is to say, in your kitchen."
The millionaire led the way down the stairs, and descended the back stairway which led to the domain of the absent cook. He turned on the electric light as they entered.
There was no sign of an intruder.
"That is the cellar door," indicated Mr. Farrington, "this the larder, and this leads to the area passage. It is locked."
T. B. tried the handle, and the door opened readily.
"This at any rate is open," he said, and entered the dark passageway.
"A mistake on the part of the butler," said the puzzled Mr. Farrington. "I have given the strictest orders that all these doors should be fastened. You will find the area door bolted and chained."
T. B. threw the rays of his electric torch over the door.
"It doesn't seem to be," he remarked; "in fact, the door is ajar."
Farrington gasped.
