"Well, sir, there's the old Squire's duelling pistols, rather out of date, sir; then your own pair and that American revolver."

"Is the revolver in working order?"

"Oh yes, sir."

"Then bring it to me and some cartridges."

When Brown returned with the revolver his master took it and examined it.

"Be careful, sir," said Brown, anxiously. "You know it's a self-c.o.c.ker, sir."

"A what?"

"A self-c.o.c.king revolver, sir"--trying to repress his astonishment at the question his master asked about a weapon with which he should have been familiar.

"Show me what you mean," said Allen, handing back the revolver.

Brown explained that the mere pulling of the trigger fired the weapon.

"Now shoot at the end window--never mind the gla.s.s. Don't stand gaping at me, do as I tell you."

Brown fired the revolver, and a diamond pane snapped out of the window.

"How many times will that shoot without reloading?"

"Seven times, sir."

"Very good. Put in a cartridge for the one you fired and leave the revolver with me. Find out when there is a train to town, and let me know."

It will be remembered that the dining-room incident was used at the trial, but without effect, as going to show that Bernard Heaton was insane. Brown also testified that there was something queer about his master that day.

David Allen found all the money he needed in the pockets of Bernard Heaton. He caught his train, and took a cab from the station directly to the law offices of Messrs. Grey, Leason and Grey, anxious to catch the lawyer before he left for the day.

The clerk sent up word that Mr. Heaton wished to see the senior Mr.

Grey for a few moments. Allen was asked to walk up.

"You know the way, sir," said the clerk.

Allen hesitated.

"Announce me, if you please."

The clerk, being well trained, showed no surprise, but led the visitor to Mr. Grey's door.

"How are you, Heaton?" said the lawyer, cordially. "Take a chair. Where have you been keeping yourself this long time? How are the Indian experiments coming on?"

"Admirably, admirably," answered Allen.

At the sound of his voice the lawyer looked up quickly, then apparently rea.s.sured he said--

"You're not looking quite the same. Been keeping yourself too much indoors, I imagine. You ought to quit research and do some shooting this autumn."

"I intend to, and I hope then to have your company."

"I shall be pleased to run down, although I am no great hand at a gun."

"I want to speak with you a few moments in private. Would you mind locking the door so that we may not be interrupted?"

"We are quite safe from interruption here," said the lawyer, as he turned the key in the lock; then resuming his seat he added, "Nothing serious, I hope?"

"It is rather serious. Do you mind my sitting here?" asked Allen, as he drew up his chair so that he was between Grey and the door, with the table separating them. The lawyer was watching him with anxious face, but without, as yet, serious apprehension.

"Now," said Allen, "will you answer me a simple question? To whom are you talking?"

"To whom--?" The lawyer in his amazement could get no further.

"Yes. To whom are you talking? Name him."

"Heaton, what is the matter with you? Are you ill?"

"Well, you have mentioned a name, but, being a villain and a lawyer, you cannot give a direct answer to a very simple question. You think you are talking to that poor fool Bernard Heaton. It is true that the body you are staring at is Heaton's body, but the man you are talking to is--David Allen--the man you swindled and then murdered. Sit down.

If you move you are a dead man. Don't try to edge to the door. There are seven deaths in this revolver and the whole seven can be let loose in less than that many seconds, for this is a self-c.o.c.king instrument.

Now it will take you at least ten seconds to get to the door, so remain exactly where you are. That advice will strike you as wise, even if, as you think, you have to do with a madman. You asked me a minute ago how the Indian experiments were coming on, and I answered admirably.

Bernard Heaton left his body this morning, and I, David Allen, am now in possession of it. Do you understand? I admit it is a little difficult for the legal mind to grasp such a situation."

"Ah, not at all," said Grey, airily. "I comprehend it perfectly. The man I see before me is the spirit, life, soul, whatever you like to call it--of David Allen in the body of my friend Bernard Heaton. The-- ah--essence of my friend is at this moment fruitlessly searching for his missing body. Perhaps he is in this room now, not knowing how to get out a spiritual writ of ejectment against you."

"You show more quickness than I expected of you," said Allen.

"Thanks," rejoined Grey, although he said to himself, "Heaton has gone mad! stark staring mad, as I expected he would. He is armed. The situation is becoming dangerous. I must humour him."

"Thanks. And now may I ask what you propose to do? You have not come here for legal advice. You never, unluckily for me, were a client of mine."

"No. I did not come either to give or take advice. I am here, alone with you--you gave orders that we were not to be disturbed, remember-- for the sole purpose of revenging myself on you and on Heaton. Now listen, for the scheme will commend itself to your ingenious mind. I shall murder you in this room. I shall then give myself up. I shall vacate this body in Newgate prison and your friend may then resume his tenancy or not as he chooses. He may allow the unoccupied body to die in the cell or he may take possession of it and be hanged for murder.

Do you appreciate the completeness of my vengeance on you both? Do you think your friend will care to put on his body again?"

[Ill.u.s.tration: "WHEN YOU PRESS THE IVORY b.u.t.tON, I FIRE"]

"It is a nice question," said the lawyer, as he edged his chair imperceptibly along and tried to grope behind himself, unperceived by his visitor, for the electric b.u.t.ton, placed against the wall. "It is a nice question, and I would like to have time to consider it in all its bearings before I gave an answer."

"You shall have all the time you care to allow yourself. I am in no hurry, and I wish you to realise your situation as completely as possible. Allow me to say that the electric b.u.t.ton is a little to the left and slightly above where you are feeling for it. I merely mention this because I must add, in fairness to you, that the moment you touch it, time ends as far as you are concerned. When you press the ivory b.u.t.ton, I fire."

The lawyer rested his arms on the table before him, and for the first time a hunted look of alarm came into his eyes, which died out of them when, after a moment or two of intense fear, he regained possession of himself.

"I would like to ask you a question or two," he said at last.

"As many as you choose. I am in no hurry, as I said before."

"I am thankful for your reiteration of that. The first question is then: has a temporary residence in another sphere interfered in any way with your reasoning powers?"
