"I am," I said. "I'm going to have nervous prostration if this thing keeps up. You're not looking particularly happy yourself."

"I'm not happy. I've let that fellow kill a man right under my nose --literally, under my nose!--and then get away!"

"Kill a man?" I repeated. "Do you mean...."

"Go upstairs and look at the right hand of the man lying there," said G.o.dfrey, curtly, "and you'll see what I mean!"

I sat staring at him, unable to believe that I had heard aright; unable to believe that G.o.dfrey had really uttered those words ... the right hand of the man lying there ... that could mean only one thing....

Simmonds joined us with a twisted smile on his lips, and I saw that even he was considerably shaken.

"I got Grady," he said, "and told him what had happened. He says he's too busy to come up, and that I'm to take charge of things."

G.o.dfrey laughed a little mocking laugh.

"Grady foresees his Waterloo!" he said. "Well, it's not far distant.

But I'm glad for your sake, Simmonds--you're going to get some glory out of this thing, yet!"

"I hope so," and Simmonds's eyes gleamed an instant. "The ambulance will be around at once," he added. "We'd better get our shoes on, and go back upstairs, and see if anything can be done for that fellow."

"There can't anything be done for him," said G.o.dfrey wearily; "but we'd better have a look at him, I guess," and he led the way out into the hall.

Not until Simmonds spoke did I remember that I was shoeless. Now I sat down beside G.o.dfrey, got fumblingly into my shoes again, and then followed him and Simmonds slowly up the stair.

I thought I knew what was pa.s.sing in G.o.dfrey's mind: he was blaming himself for this latest tragedy; he was telling himself that he should have foreseen and prevented it; he always blamed himself in that way when things went wrong--and then, to have the murderer slip through his very fingers! I could guess what a mighty shock that had been to his self-confidence!

The latest victim was lying where he had fallen, just inside the doorway leading into the inner room. Simmonds stepped to the window, threw open the shutters, and let a flood of afternoon sunshine into the room. Then he knelt beside the body, and held up the limp right hand for us to see.

Just above the knuckles were two tiny incisions, with a drop or two of blood oozing away from them, and the flesh about them swollen and discoloured.

"I knew what it was the instant he yelled '_La mort!_'" said G.o.dfrey quietly. "And _he_ knew what it was the instant he felt the stroke.

It is evident enough that he had seen it used before, or heard of it, and knew that it meant instant death."

I sat down, staring at the dead man, and tried to collect my senses.

So this fiendish criminal, who slew with poison, had been lurking in Vantine's house, and had struck down first Drouet and then the master of the house himself! But why--why! It was incredible, astounding, my brain reeled at the thought. And yet it must be true!

I looked again at the third victim, and saw a man roughly dressed, with bushy black hair and tangled beard; a very giant of a man, whose physical strength must have been enormous--and yet it had availed him nothing against that tiny pin-p.r.i.c.k on the hand!

And then a sudden thought brought me bolt upright.

"But Armand!" I cried. "Where is Armand?"

G.o.dfrey looked at me with a half-pitying smile.

"What, Lester!" he said, "don't you understand, even yet? It was your fascinating M. Armand who did that," and he pointed to the dead man.

I felt as though I had been struck a heavy blow upon the head; black circles whirled before my eyes....

"Go over to the window," said G.o.dfrey, peremptorily, "and get some fresh air."

Mechanically I obeyed, and stood clinging to the window-sill, gazing down at the busy street, where the tide of humanity was flowing up and down, all unconscious of the tragedy which had been enacted so close at hand. And, at last, the calmness of all these people, the sight of the world going quietly on as usual, restored me a portion of my self-control. But even yet I did not understand.

"Was it Armand," I asked, turning back into the room, "who lay there in the corner?"

"Certainly it was," G.o.dfrey answered. "Who else could it be?"

"G.o.dfrey!" I cried, remembering suddenly. "Did you see his eyes as he lay there watching the man at the cabinet?"

"Yes; I saw them."

"They were the same eyes...."

"The same eyes."

"And the laugh--did you hear that laugh?"

"Certainly I heard it."

"I heard it once before," I said, "and you thought it was a case of nerves!"

I fell silent a moment, shivering a little at the remembrance.

"But why did Armand lie there so quietly?" I asked, at last. "Was he injured?"

G.o.dfrey made a little gesture toward the corner.

"Go see for yourself," he said.

Something lay along the wall, on the spot where I had seen that figure, and as I bent over it, I saw that it was a large net, finely meshed but very strong.

"That was dropped over Armand's head as he came up the stairs," said G.o.dfrey, "or flung over him as he came into the room. Then the dead man yonder jumped upon him and trussed him up with those ropes."

Pushing the net aside, I saw upon the floor a little pile of severed cords.

"Yes," I agreed; "he would be able to do that. Have you noticed his size, G.o.dfrey? He was almost a giant!"

"He couldn't have done it if Armand hadn't been willing that he should," retorted G.o.dfrey, curtly. "You see he had no difficulty in getting away," and he held up the net and pointed to the great rents in it. "He cut his way out while he was lying there--I ought to have known--I ought to have known he wasn't bound--that he was only waiting--but it was all so sudden...."

He threw the net down upon the floor with a gesture of disgust and despair. Then he stopped in front of the Boule cabinet and looked down at it musingly; and, after a moment, his face brightened.

The burlap wrappings had been almost wholly torn away, and the cabinet stood, more insolently beautiful than ever, it seemed to me, under the rays of the sun, which sparkled and glittered and shimmered as they fell upon it.

"But we'll get him, Simmonds," said G.o.dfrey, and his lips broke into a smile. "In fact, we've got him now. We have only to wait, and he'll walk into our arms. Simmonds, I want you to lock this cabinet up in the strongest cell around at your station; and carry the key yourself."

"Lock it up?" stammered Simmonds, staring at him.

"Yes," said G.o.dfrey, "lock it up. That's our one salvation!" His face was glowing; he was quite himself again, alert, confident of victory.

"You're in charge of this case, aren't you? Well, lock it up, and give your reasons to n.o.body."
