Craig stopped the boy who was about to announce us and asked for Bennett's secretary instead, much to my astonishment.

The boy merely indicated the door of one of the other private offices, and we entered.

We found the secretary, hard at work at the typewriter, copying a legal doc.u.ment. Without a word, Kennedy at once locked the door.

The secretary rose in surprise, but Craig paid no attention to him.

Instead he calmly walked over to the machine and began to examine it.

"Might I ask--" began the secretary.

"You keep quiet," ordered Kennedy, with a nod to me to watch the fellow. "You are under arrest--and the less you say, the better for you."

I shall never forget the look that crossed the secretary's face. Was it the surprise of an innocent man?

Taking the man's place at the machine, Kennedy removed the legal paper that was in it and put in a new sheet. Then he tapped out, as we watched:

BE AT HEADQUARTERS AT 12. DESTROY THIS IMMEDIATELY

TINCTURE OF IODINE

THREE PARTS OF----

This is his contention:--whereas TRUTH is the only goal and MATTER is non-existent--

T T T T

"Look, Walter," he exclaimed as he drew out the paper from the machine.

I bent over and together we compared the T's with those in the Clutching Hand letter, the paper from the bomb and the letter which Craig had taken from Elaine's desk.

As Craig pointed out the resemblances with a pencil, my amazement gradually changed into comprehension and comprehension into conviction.

The meaning of it all began to dawn on me.

The writing was identical. There were no differences!

While we were locked in the secretary's office, Bennett and Elaine were continuing their chat on various social topics. Suddenly, however, with a glance at the clock, Bennett told Elaine that he had an important letter to dictate, and that it must go off at once.

She said that she would excuse him a few minutes and he pressed a b.u.t.ton to call his secretary.

Of course the secretary did not appear. Bennett left his office, with some annoyance, and went into the adjoining room the door to which Kennedy had not locked.

He hesitated a moment, then opened the door quietly. To his astonishment, he saw Kennedy, the secretary, and myself apparently making a close examination of the typewriter.

Gliding rather than walking back into his own office, he closed the door and locked it. Almost instantly, fear and fury at the presence of his hated rival, Kennedy, turned Bennett, as it were, from the Jekyll of a polished lawyer and lover of Elaine into an insanely jealous and revengeful Mr. Hyde. The strain was more than his warped mind could bear.

With a look of intense horror and loathing, Elaine watched him slowly change from the composed, calm, intellectual Bennett she knew and respected into a repulsive, mad figure of a man.

His stature even seemed to be altered. He seemed to shrivel up and become deformed. His face was terribly distorted.

And his long, sinewy hand slowly twisted and bent until he became the personal embodiment of the Clutching Hand.

As Elaine, transfixed with terror, watched Bennett's astounding metamorphosis, he ran to the door leading to the outer office and hastily locked that, also.

Then, with his eyes gleaming with rage and his hands working in murderous frenzy, he crouched, nearer and nearer, towards Elaine.

She shrank back, screaming again and again in terror.

He WAS the Clutching Hand!

In spite of closed doors, we could now plainly hear Elaine's shrieks.

Craig, the secretary and myself made a rush for the door to Bennett's private office. Finding it locked, we began to batter it.

By this time, however, Bennett had hurled himself upon Elaine and was slowly choking her.

Kennedy quickly found that it was impossible to batter down the door in time by any ordinary means. Quickly he seized the typewriter and hurled it through the panels. Then he thrust his hand through the opening and turned the catch.

As we flung ourselves into the room, Bennett rushed into a closet in a corner, slamming the door behind him. It was composed of sheet iron and effectually prevented anyone from breaking through. Kennedy and I tried vainly, however, to pry it open.

While we were thus endeavoring to force an entrance, Bennett, in a sort of closet, had put on the coat, hat and mask which he invariably wore in the character of the Clutching Hand. Then he cautiously opened a secret door in the back of the closet and slowly made an exit.

Meanwhile, the secretary had been doing his best to revive Elaine, who was lying in a chair, hysterical and half unconscious from the terrible shock she had experienced.

Intent on discovering Bennett's whereabouts, Kennedy and I examined the wall of the office, thinking there might possibly be some b.u.t.ton or secret spring which would open the closet door.

While we were doing so, the door of a large safe in the secretary's office gradually opened and the Clutching Hand emerged from it, stepping carefully towards the door leading to the outer office, intent on escaping in that direction.

At that moment, I caught sight of him, and leaping into the secretary's office, I drew my revolver and ordered him to throw up his hands. He obeyed. Holding up both hands, he slowly drew near the door to his private office.

Suddenly he dropped one hand and pressed a hidden spring in the wall.

Instantly a heavy iron door shot out and closed over the wooden door.

Entrance to the private office was absolutely cut off.

With an angry snarl, the Clutching Hand leaped at me.

As he did so, I fired twice.

He staggered back.

The shots were heard by Kennedy and Elaine, as well as the secretary, and at the same instant they discovered the iron door which barred the entrance to the secretary's office.
