seemed equally anxious to have the marauder apprehended, whoever he might be.
"My dear," he said to her at length, "will you call some one and have them taken to the kitchen?"
Chapter IX
The Elixir of Life
As Minna Pitts led us through the large mansion preparatory to turning us over to a servant she explained hastily that Mr. Pitts had long been ill and was now taking a new treatment under Dr. Thompson Lord. No one having answered her bell in the present state of excitement of the house, she stopped short at the pivoted door of the kitchen, with a little shudder at the tragedy, and stood only long enough to relate to us the story as she had heard it from the valet, Edward.
Mr. Pitts, it seemed, had wanted an early breakfast and had sent Edward to order it. The valet had found the kitchen a veritable slaughter-house, with the negro chef, Sam, lying dead on the floor. Sam had been dead, apparently, since the night before.
As she hurried away, Kennedy pushed open the door. It was a marvellous place, that antiseptic or rather aseptic kitchen, with its white tiling and enamel, its huge ice-box, and cooking-utensils for every purpose, all of the most expensive and modern make.
There were marks everywhere of a struggle, and by the side of the chef, whose body now lay in the next room awaiting the coroner, lay a long carving-knife with which he had evidently defended himself. On its blade and haft were huge coagulated spots of blood. The body of Sam bore marks of his having been clutched violently by the throat, and in his head was a single, deep wound that penetrated the skull in a most peculiar manner. It did not seem possible that a blow from a knife could have done it. It was a most unusual wound and not at all the sort that could have been made by a bullet.
As Kennedy examined it, he remarked, shaking his head in confirmation of his own opinion, "That must have been done by a Behr bulletless gun."
"A bulletless gun?" I repeated.
"Yes, a sort of pistol with a spring-operated device that projects a sharp blade with great force. No bullet and no powder are used in it. But when it is placed directly over a vital point of the skull so that the aim is unerring, a trigger lets a long knife shoot out with tremendous force, and death is instantaneous."
Near the door, leading to the courtyard that opened on the side street, were some spots of blood. They were so far from the place where the valet had discovered the body of the chef that there could be no doubt that they were blood from the murderer himself. Kennedy's reasoning in the matter seemed irresistible.
He looked under the table near the door, covered with a large light cloth. Beneath the table and behind the cloth he found another blood spot.
"How did that land there?" he mused aloud. "The table-cloth is bloodless."
Craig appeared to think a moment. Then he unlocked and opened the door. A current of air was created and blew the cloth aside.
"Clearly," he exclaimed, "that drop of blood was wafted under the table as the door was opened. The chances are all that it came from a cut on perhaps the hand or face of the murderer himself."
It seemed to be entirely reasonable, for the bloodstains about the room were such as to indicate that he had been badly cut by the carving-knife.
"Whoever attacked the chef must have been deeply wounded," I remarked, picking up the bloody knife and looking about at the stains, comparatively few of which could have come from the one deep fatal wound in the head of the victim.
Kennedy was still engrossed in a study of the stains, evidently considering that their size, shape, and location might throw some light on what had occurred. "Walter," he said finally, "while I'm busy here, I wish, you would find that valet, Edward. I want to talk to him."
I found him at last, a clean-cut young fellow of much above average intelligence.
"There are some things I have not yet got clearly, Edward," began Kennedy. "Now where was the body, exactly, when you opened the door?"
Edward pointed out the exact spot, near the side of the kitchen toward the door leading out to the breakfast room and opposite the ice-box.
"And the door to the side street?" asked Kennedy, to all appearances very favorably impressed by the young man.
"It was locked, sir," he answered positively.
Kennedy was quite apparently considering the honesty and faithfulness of the servant. At last he leaned over and asked quickly, "Can I trust you?"
The frank, "Yes," of the young fellow was convincing enough.
"What I want," pursued Kennedy, "is to have some one inside this house who can tell me as much as he can see of the visitors, the messengers that come here this morning. It will be an act of loyalty to your employer, so that you need have no fear about that."
Edward bowed, and left us. While I had been seeking him, Kennedy had telephoned hastily to his laboratory and had found one of his students there. He had ordered him to bring down an apparatus which he described, and some other material.
While we waited Kennedy sent word to Pitts that he wanted to see him alone for a few minutes.
The instrument appeared to be a rubber bulb and cuff with a rubber bag attached to the inside. From it ran a tube which ended in another graduated glass tube with a thin line of mercury in it like a thermometer.
Craig adjusted the thing over the brachial artery of Pitts, just above the elbow.
"It may be a little uncomfortable, Mr. Pitts," he apologised, "but it will be for only a few minutes."
Pressure through the rubber bulb shut off the artery so that Kennedy could no longer feel the pulse at the wrist. As he worked, I began to see what he was after. The reading on the graded scale of the height of the column of mercury indicated, I knew, blood pressure. This time, as he worked, I noted also the flabby skin of Pitts as well as the small and sluggish pupils of his eyes.
He completed his test in silence and excused himself, although as we went back to the kitchen I was burning with curiosity.
"What was it?" I asked. "What did you discover?"
"That," he replied, "was a sphygmomanometer, something like the sphygmograph which we used once in another case. Normal blood pressure is 125 millimetres. Mr. Pitts shows a high pressure, very high. The large life insurance companies are now using this instrument. They would tell you that a high pressure like that indicates apoplexy. Mr. Pitts, young as he really is, is actually old. For, you know, the saying is that a man is as old as his arteries. Pitts has hardening of the arteries, arteriosclerosis—perhaps other heart and kidney troubles, in short pre-senility."
Craig paused: then added sententiously as if to himself: "You have heard the latest theories about old age, that it is due to microbic poisons secreted in the intestines and penetrating the intestinal walls? Well, in premature senility the symptoms are the same as in senility, only mental acuteness is not so impaired."
We had now reached the kitchen again. The student had also brought down to Kennedy a number of sterilised microscope slides and test-tubes, and from here and there in the masses of blood spots Kennedy was taking and preserving samples. He also took samples of the various foods, which he preserved in the sterilised tubes.
While he was at work Edward joined us cautiously.
"Has anything happened?" asked Craig.
"A message came by a boy for Mrs. Pitta," whispered the valet.
"What did she do with it?"
"Tore it up."
"And the pieces?"
"She must have hidden them somewhere."
"See if you can get them."
Edward nodded and left us.
