Although the house seemed deserted, Craig took no chances, but directed the car to turn at the next crossroad and then run back along a road back of and parallel to that on which Annenberg’s was situated. It was perhaps a quarter of a mile away, across an open field, that we stopped and ran the car up along the side of the road in some bushes. Annenberg’s was plainly visible and it was not at all likely that anyone there would suspect trouble from that quarter.

A hasty conference with Burke followed, in which Kennedy unwrapped his small package, leaving part of its contents with him, and adding careful instructions.

Then Kennedy and I retraced our steps down the road, across by the crossroad, and at last back to the mysterious house.

To all appearance there had been no need of such excessive caution. Not a sound or motion greeted us as we entered the gate and made our way around to the rear of the house. The very isolation of the house was now our protection, for we had no inquisitive neighbors to watch us for the instant when Kennedy, with the dexterity of a yeggman, inserted his knife between the sashes of the kitchen window and turned the catch which admitted us.

We made our way on cautious tiptoe through a dining room to a living room, and, finding nothing, proceeded upstairs. There was not a soul, apparently, in the house, nor in fact anything to indicate that it was different from most small suburban homes, until at last we mounted to the attic.

It was finished off in one large room across the back of the house and two in front. As we opened the door to the larger room, we could only gaze about in surprise. This was the rendezvous, the arsenal, literary, explosive and toxicological of the “Group.” Ranged on a table were all the materials for bomb-making, while in a cabinet I fancied there were poisons enough to decimate a city.

On the walls were pictures, mostly newspaper prints, of the assassins of McKinley, of King Humbert, of the King of Greece, of King Carlos and others, interspersed with portraits of anarchist and anti-militarist leaders of all lands.

Kennedy sniffed. Over all I, too, could catch the faint odor of stale tobacco. No time was to be lost, however, and while Craig set to work rapidly going through the contents of a desk in the corner, I glanced over the contents of a drawer of a heavy mission table.

“Here’s some of Annenberg’s literature,” I remarked, coming across a small pile of manuscript, entitled “The Human Slaughter House.”

“Read it,” panted Kennedy, seeing that I had about completed my part of the job. “It may give a clue.”
