T. X. pointed the thing downward to the carpet and pressed the k.n.o.b cautiously. As he did so there was a sharp hiss and the floor was stained with the liquid which the instrument contained. Just one gush of fluid and no more. T. X. looked down. The bright carpet had already changed colour, and was smoking. The room was filled with a pungent and disagreeable scent. T. X. looked from the floor to the white-faced man.

"Vitriol, I believe," he said, shaking his head admiringly. "What a dear little fellow you are!"

The man, big as he was, was on the point of collapse and mumbled something about self-defence, and listened without a word, whilst T.

X., labouring under an emotion which was perfectly pardonable, described Kara, his ancestors and the possibilities of his future estate.

Very slowly the Greek recovered his self-possession.

"I didn't intend using it on you, I swear I didn't," he pleaded.

"I'm surrounded by enemies, Meredith. I had to carry some means of protection. It is because my enemies know I carry this that they fight shy of me. I'll swear I had no intention of using it on you. The idea is too preposterous. I am sorry I fooled you about the safe."

"Don't let that worry you," said T. X. "I am afraid I did all the fooling. No, I cannot let you have this back again," he said, as the Greek put out his hand to take the infernal little instrument. "I must take this back to Scotland Yard; it's quite a long time since we had anything new in this shape. Compressed air, I presume."

Kara nodded solemnly.

"Very ingenious indeed," said T. X. "If I had a brain like yours," he paused, "I should do something with it--with a gun," he added, as he pa.s.sed out of the room.

CHAPTER IX

"My dear Mr. Meredith,

"I cannot tell you how unhappy and humiliated I feel that my little joke with you should have had such an uncomfortable ending. As you know, and as I have given you proof, I have the greatest admiration in the world for one whose work for humanity has won such universal recognition.

"I hope that we shall both forget this unhappy morning and that you will give me an opportunity of rendering to you in person, the apologies which are due to you. I feel that anything less will neither rehabilitate me in your esteem, nor secure for me the remnants of my shattered self-respect.

"I am hoping you will dine with me next week and meet a most interesting man, George Gathercole, who has just returned from Patagonia,--I only received his letter this morning-- having made most remarkable discoveries concerning that country.

"I feel sure that you are large enough minded and too much a man of the world to allow my foolish fit of temper to disturb a relationship which I have always hoped would be mutually pleasant. If you will allow Gathercole, who will be unconscious of the part he is playing, to act as peacemaker between yourself and myself, I shall feel that his trip, which has cost me a large sum of money, will not have been wasted.

"I am, dear Mr. Meredith,

"Yours very sincerely,

"REMINGTON KARA."

Kara folded the letter and inserted it in its envelope. He rang a bell on his table and the girl who had so filled T. X. with a sense of awe came from an adjoining room.

"You will see that this is delivered, Miss Holland."

She inclined her head and stood waiting. Kara rose from his desk and began to pace the room.

"Do you know T. X. Meredith?" he asked suddenly.

"I have heard of him," said the girl.

"A man with a singular mind," said Kara; "a man against whom my favourite weapon would fail."

She looked at him with interest in her eyes.

"What is your favourite weapon, Mr. Kara?" she asked.

"Fear," he said.

If he expected her to give him any encouragement to proceed he was disappointed. Probably he required no such encouragement, for in the presence of his social inferiors he was somewhat monopolizing.

"Cut a man's flesh and it heals," he said. "Whip a man and the memory of it pa.s.ses, frighten him, fill him with a sense of foreboding and apprehension and let him believe that something dreadful is going to happen either to himself or to someone he loves--better the latter--and you will hurt him beyond forgetfulness. Fear is a tyrant and a despot, more terrible than the rack, more potent than the stake. Fear is many-eyed and sees horrors where normal vision only sees the ridiculous."

"Is that your creed?" she asked quietly.

"Part of it, Miss Holland," he smiled.

She played idly with the letter she held in her hand, balancing it on the edge of the desk, her eyes downcast.

"What would justify the use of such an awful weapon?" she asked.

"It is amply justified to secure an end," he said blandly. "For example--I want something--I cannot obtain that something through the ordinary channel or by the employment of ordinary means. It is essential to me, to my happiness, to my comfort, or my amour-propre, that that something shall be possessed by me. If I can buy it, well and good. If I can buy those who can use their influence to secure this thing for me, so much the better. If I can obtain it by any merit I possess, I utilize that merit, providing always, that I can secure my object in the time, otherwise--"

He shrugged his shoulders.

"I see," she said, nodding her head quickly. "I suppose that is how blackmailers feel."

He frowned.

"That is a word I never use, nor do I like to hear it employed," he said. "Blackmail suggests to me a vulgar attempt to obtain money."

"Which is generally very badly wanted by the people who use it," said the girl, with a little smile, "and, according to your argument, they are also justified."

"It is a matter of plane," he said airily. "Viewed from my standpoint, they are sordid criminals--the sort of person that T. X. meets, I presume, in the course of his daily work. T. X.," he went on somewhat oracularly, "is a man for whom I have a great deal of respect. You will probably meet him again, for he will find an opportunity of asking you a few questions about myself. I need hardly tell you--"

He lifted his shoulders with a deprecating smile.

"I shall certainly not discuss your business with any person," said the girl coldly.

"I am paying you 3 pounds a week, I think," he said. "I intend increasing that to 5 pounds because you suit me most admirably."

"Thank you," said the girl quietly, "but I am already being paid quite sufficient."

She left him, a little astonished and not a little ruffled.

To refuse the favours of Remington Kara was, by him, regarded as something of an affront. Half his quarrel with T. X. was that gentleman's curious indifference to the benevolent att.i.tude which Kara had persistently adopted in his dealings with the detective.

He rang the bell, this time for his valet.

"Fisher," he said, "I am expecting a visit from a gentleman named Gathercole--a one-armed gentleman whom you must look after if he comes.
