Our next visit was to the district attorney, a young man, Gordon Kilgore, who seemed not unwilling to discuss the case frankly.

"I want to make arrangements for disinterring the body," explained Kennedy. "Would you fight such a move?"

"Not at all, not at all," he answered brusquely. "Simply make the arrangements through Kahn. I shall interpose no objection. It is the strongest, most impregnable part of the case, the discovery of the poison. If you can break that down you will do more than any one else has dared to hope. But it can't be done. The proof was too strong. Of course it is none of my business, but I'd advise some other point of attack."

I must confess to a feeling of disappointment when Kennedy announced after leaving Kilgore that, for the present, there was nothing more to be done at East Point until Kahn had made the arrangements for reopening the grave.

We motored back to Ossining, and Kennedy tried to be rea.s.suring to Mrs.

G.o.dwin.

"By the way," he remarked, just before we left, "you used a good deal of canned goods at the G.o.dwin house, didn't you?"

"Yes, but not more than other people, I think," she said.

"Do you recall using any that were--well, perhaps not exactly spoiled, but that had anything peculiar about them?"

"I remember once we thought we found some cans that seemed to have been attacked by mice--at least they smelt so, though how mice could get through a tin can we couldn't see."

"Mice?" queried Kennedy. "Had a mousey smell? That's interesting. Well, Mrs. G.o.dwin, keep up a good heart. Depend on me. What you have told me to-day has made me more than interested in your case. I shall waste no time in letting you know when anything encouraging develops."

Craig had never had much patience with red tape that barred the way to the truth, yet there were times when law and legal procedure had to be respected, no matter how much they hampered, and this was one of them.

The next day the order was obtained permitting the opening again of the grave of old Mr. G.o.dwin. The body was exhumed, and Kennedy set about his examination of what secrets it might hide.

Meanwhile, it seemed to me that the suspense was terrible. Kennedy was moving slowly, I thought. Not even the courts themselves could have been more deliberate. Also, he was keeping much to himself.

Still, for another whole day, there was the slow, inevitable approach of the thing that now, I, too, had come to dread--the handing down of the final decision on the appeal.

Yet what could Craig do otherwise, I asked myself. I had become deeply interested in the case by this time and spent the time reading all the evidence, hundreds of pages of it. It was cold, hard, brutal, scientific fact, and as I read I felt that hope faded for the ashen-faced man and the pallid little woman. It seemed the last word in science. Was there any way of escape?

Impatient as I was, I often wondered what must have been the suspense of those to whom the case meant everything.

"How are the tests coming along?" I ventured one night, after Kahn had arranged for the uncovering of the grave.

It was now two days since Kennedy had gone up to East Point to superintend the exhumation and had returned to the city with the materials which had caused him to keep later hours in the laboratory than I had ever known even the indefatigable Craig to spend on a stretch before.

He shook his head doubtfully.

"Walter," he admitted, "I'm afraid I have reached the limit on the line of investigation I had planned at the start."

I looked at him in dismay. "What then?" I managed to gasp.

"I am going up to East Point again to-morrow to look over that house and start a new line. You can go."

No urging was needed, and the following day saw us again on the ground.

The house, as I have said, had been almost torn to pieces in the search for the will and the poison evidence. As before, we went to it unannounced, and this time we had no difficulty in getting in. Kennedy, who had brought with him a large package, made his way directly to a sort of drawing-room next to the large library, in the closet of which the will had been discovered.

He unwrapped the package and took from it a huge brace and bit, the bit a long, thin, murderous looking affair such as might have come from a burglar's kit. I regarded it much in that light.

"What's the lay?" I asked, as he tapped over the walls to ascertain of just what they were composed.

Without a word he was now down on his knees, drilling a hole in the plaster and lath. When he struck an obstruction he stopped, removed the bit, inserted another, and began again.

"Are you going to put in a detectaphone?" I asked again.

He shook his head. "A detectaphone wouldn't be of any use here," he replied. "No one is going to do any talking in that room."

Again the brace and bit were at work. At last the wall had been penetrated, and he quickly removed every trace from the other side that would have attracted attention to a little hole in an obscure corner of the flowered wall-paper.

Next, he drew out what looked like a long putty-blower, perhaps a foot long and three-eighths of an inch in diameter.

"What's that?" I asked, as he rose after carefully inserting it.

"Look through it," he replied simply, still at work on some other apparatus he had brought.

I looked. In spite of the smallness of the opening at the other end, I was amazed to find that I could see nearly the whole room on the other side of the wall.

"It's a detectascope," he explained, "a tube with a fish-eye lens which I had an expert optician make for me."

"A fish-eye lens?" I repeated.

"Yes. The focus may be altered in range so that any one in the room may be seen and recognised and any action of his may be detected. The original of this was devised by Gaillard Smith, the adapter of the detectaphone. The instrument is something like the cytoscope, which the doctors use to look into the human interior. Now, look through it again. Do you see the closet?"

Again I looked. "Yes," I said, "but will one of us have to watch here all the time?"

He had been working on a black box in the meantime, and now he began to set it up, adjusting it to the hole in the wall which he enlarged on our side.

"No, that is my own improvement on it. You remember once we used a quick-shutter camera with an electric attachment, which moved the shutter on the contact of a person with an object in the room? Well, this camera has that quick shutter. But, in addition, I have adapted to the detectascope an invention by Professor Robert Wood, of Johns Hopkins. He has devised a fish-eye camera that 'sees' over a radius of one hundred and eighty degrees--not only straight in front, but over half a circle, every point in that room.

"You know the refracting power of a drop of water. Since it is a globe, it refracts the light which reaches it from all directions. If it is placed like the lens of a camera, as Dr. Wood tried it, so that one-half of it catches the light, all the light caught will be refracted through it. Fishes, too, have a wide range of vision. Some have eyes that see over half a circle. So the lens gets its name.

Ordinary cameras, because of the flatness of their lenses, have a range of only a few degrees, the widest in use, I believe, taking in only ninety-six, or a little more than a quarter of a circle. So, you see, my detectascope has a range almost twice as wide as that of any other."

Though I did not know what he expected to discover and knew that it was useless to ask, the thing seemed very interesting. Craig did not pause, however, to enlarge on the new machine, but gathered up his tools and announced that our next step would be a visit to a lawyer whom the Elmores had retained as their personal counsel to look after their interests, now that the district attorney seemed to hare cleared up the criminal end of the case.

Hollins was one of the prominent attorneys of East Point, and before the election of Kilgore as prosecutor had been his partner. Unlike Kilgore, we found him especially uncommunicative and inclined to resent our presence in the case as intruders.

The interview did not seem to me to be productive of anything. In fact, it seemed as if Craig were giving Hollins much more than he was getting.

"I shall be in town over night," remarked Craig. "In fact, I am thinking of going over the library up at the G.o.dwin house soon, very carefully." He spoke casually. "There may be, you know, some finger-prints on the walls around that closet which might prove interesting."

A quick look from Hollins was the only answer. In fact, it was seldom that he uttered more than a monosyllable as we talked over the various aspects of the case.

A half-hour later, when he had left and had gone to the hotel, I asked Kennedy suspiciously, "Why did you expose your hand to Hollins, Craig?"

He laughed. "Oh, Walter," he remonstrated, "don't you know that it is nearly always useless to look for finger-prints, except under some circ.u.mstances, even a few days afterward? This is months, not days. Why on iron and steel they last with tolerable certainty only a short time, and not much longer on silver, gla.s.s, or wood. But they are seldom permanent unless they are made with ink or blood or something that leaves a more or less indelible mark. That was a 'plant.'"

"But what do you expect to gain by it?"

"Well," he replied enigmatically, "no one is necessarily honest."
