studio with the Star's photoplay editor. I was anxious to impress my knowledge upon Kennedy. He gave me no opportunity, however, but wheeled upon Mackay suddenly.
"Send in the electrician," he ordered. "Keep everyone else out until I'm ready to examine them."
While the district attorney hurried to the sliding doors, guarded on their farther side by one of the amateur deputies he had impressed into service, Kennedy swung the stand of the arc he had used back into the place unaided. I noticed that Doctor Blake was nervously interested in spite of his professional poise. I certainly was bursting with curiosity to know what Kennedy had found.
The electrician, a wizened veteran of the studios, with a bald head which glistened rather ridiculously, entered as though he expected to be held for the death of the star on the spot.
"I don't know nothin'," he began, before anyone could start to question him. "I was outside when they yelled, honest! I was seeing whether m'lead was getting hot, and I heard 'em call to douse the glim, an'--"
"Put on all your lights"--Kennedy was unusually sharp, although it was plain he held no suspicion of this man, as he added--"just as you had them."
As the electrician went from stand to stand sulkily, there was a sputter from the arcs, almost deafening in the confines of the room, and quite a bit of fine white smoke. But in a moment the corner of the library constituting the set was brilliantly, dazzlingly lighted. To me it was quite like being transported into one of the big studios in the city.
"Is this the largest portion of the room they used?" Kennedy asked. "Did you have your stands any farther back?"
"This was the biggest lay-out, sir!" replied the man.
"Were all the scenes in which Miss Lamar appeared before her death in this corner of the room?"
"Yes, sir!"
"And this was the way you had the scene lighted when she dropped unconscious?"
"Yes, sir! I pulled m'lights an'--an' they lifted her up and put her right there where she is, sir!"
Kennedy paid no attention to the last; in fact, I doubt whether he heard it. Dropping to hands and knees immediately, he began a search of the floor and carpet as minutely painstaking as the inspection he had given Stella's own person. Instinctively I drew back, to be out of his way, as did Doctor Blake and Mackay. The electrician, I noticed, seemed to grasp now the reason for the summons which undoubtedly had frightened him badly. He gave his attention to his lights, stroking a refractory Cooper-Hewitt tube for all the world as if some minor scene in the story were being photographed. It was hard to realize that it was not another picture scene, but that Craig Kennedy, in my opinion the founder of the scientific school of modern detectives, was searching out in this strange environment the clue to a real murder so mysterious that the very cause of death was as yet undetermined.
I was hoping for a display of the remarkable brilliance Craig had shown in so many of the cases brought to his attention. I half expected to see him rise from the floor with some tiny something in his hand, some object overlooked by everyone else, some tangible evidence which would lead to the immediate apprehension of the perpetrator of the crime. That Stella Lamar had met her death by foul means I did not doubt for an instant, and so I waited feverishly for the conclusion of Kennedy's search.
As it happened, this was not destined to be one of his cases cleared up in a brief few hours of intensive effort. He covered every inch of the floor within the illuminated area; then he turned his attention to the walls and furniture and the rest of the room in somewhat more perfunctory, but no less skillful manner. Fully fifteen minutes elapsed, but I knew from his expression that he had discovered nothing. In a wringing perspiration from the heat of the arcs, but nevertheless glad to have had the intense light at his disposal, he motioned to the electrician to turn them off and to leave the room.
"Find anything, Mr. Kennedy?" queried the physician once more.
Kennedy beckoned all of us to the side of the ill-fated actress. Lifting the right arm, finding the spot which had caused his exclamation before, he handed his pocket lens to Doctor Blake. After a moment a low whistle escaped the lips of the physician.
Next it was my turn. As I stooped over I caught, above the faint scent of imported perfume which she affected, a peculiar putrescent odor. This it was which had caught Kennedy's nostrils. Then through the glass I could detect upon her forearm the tiniest possible scratch ending in an almost invisible puncture, such as might have been made by a very sharp needle or the point of an incredibly fine hypodermic syringe. Drawing back, I glanced again at her face, which I had already noted was blotched and somewhat swollen beneath the make-up. Again I thought that the muscles were contorted, that the eyes were bulging slightly, that there was a bluish tinge to her skin such as in cyanosis or asphyxiation. It may have been imagination, but I was now sure that her expression revealed pain or fear or both.
When I looked at her first I had been unable to forget my impression of years. Before me there had been the once living form of Stella Lamar, whom I had dreamed of meeting and whom I had never viewed in actual life. I had lacked the penetration to see beneath the glamour. But to Kennedy there had been signs of the poisoning at once. Doctor Blake had searched merely for the evidences of the commoner drugs, or the usual diseases such as cause sudden death. I recalled the cyanides. I thought of curare, or woorali, the South American arrow poison with which Kennedy once had dealt. Had Stella received an injection of some new and curious substance?
Mackay glanced up from his inspection of the mark on the arm.
"It's an awfully tiny scratch!" he exclaimed.
Kennedy smiled. "Yet, Mackay, it probably was the cause of her death."
"How?"
"That--that is the problem before us. When we learn just exactly how she scratched herself, or was scratched--" Kennedy paced up and down in front of the fireplace. Then he confronted each of us in turn, suddenly serious. "Not a word of what I have discovered," he warned.
Chapter III
Tangled Motives
"Do you wish to examine the people now?" Mackay asked.
Kennedy hesitated. "First I want to make sure of the evidence concerning her actual death. Can you arrange to have the clothes she has on, and those she brought with her, all of them bundled up and sent in to my laboratory, together with samples of her body fluids as soon as the coroner can supply you?"
Mackay nodded. This pleased him. This seemed to be tangible action, promising tangible results.
Again Kennedy glanced about in thought. I knew that the scratch was worrying him. "Did she change her clothes out here?" he inquired.
The district attorney brightened. "She dressed in a small den just off the living room. I have a man posted and the door closed. Nothing has been disturbed."
He started to lead the way without further word from Kennedy, proud to have been able once more to demonstrate his foresight
As we left the library, entering the living room, there was an appreciable hush. Here were grouped the others of the party brought out by the picture company, a constrained gathering of folk who had little in common beyond the highly specialized needs of the new art of the screen, an assembly of souls who had been forced to wait during all the time required for the trip of Kennedy and myself out from New York, who were compelled to wait now until he should be ready to examine them.
I picked out the electrician in the semi-gloom and with him his fellow members of the technical staff needed in the taking of the scenes in the library. The camera men I guessed, and a property boy, and an assistant director. The last, at any event, of all those in the huge room, had summoned up sufficient nonchalance to bend his mind to details of his work. I saw that he was thumbing a copy of the scenario, or detailed working manuscript of the story, making notations in some kind of little book, and it was that which enabled
