"Did you think I was going to forget you?" she asked, almost reproachfully and much out of breath. "Let's hurry," she added. "This is roast beef day."

We started toward the gate once more, Marilyn between us, vivacious and rather charming. I noticed that she made no reference to the incident in the hallway, the precipitate manner in which she left us and the very evident confusion of Merle Shirley. Kennedy, too, seemed disposed to drop the matter, although it was obviously significant. For some reason his mind was elsewhere, so that the girl was thrown upon my hands.

It struck me that, after all, she was attractive. At this moment I found her distinctly good-looking.

"Why do you 'vamp'?" I asked, innocently. "You don't seem to me, if you'll pardon the personal remark, at all that type."

She laughed. "It's all the fault of the public. They insist that I vamp. I want to play girly-girly parts, but the public won't stand for it; they won't come to see the picture. They tell the exhibitor, and he tells the producer, and back I am at the vamping again. Isn't it funny?" She paused a moment. "Take Gordon. Doesn't it make you laugh, what the public think he is--clean-cut, hero, and all that sort of thing? Little do they know!"

All at once Kennedy stopped abruptly. We were close to the entrance, just where a smart little speedster of light blue lined with white was parked at the edge of the narrow sidewalk. The sun, after a morning of uncertainty, had just struck through the haze, and it illuminated Marilyn's face and hair most delightfully as we both turned, somewhat in surprise.

"I know you'll never forgive me, Miss Loring," Kennedy began, "but the fact is that just before you came out we stumbled into a new bit of evidence in the case and I believe that Jameson and I will have to hurry in to the laboratory. Much as I would like to lunch with you, and perhaps chat some more during scene-taking this afternoon--"

It seemed to me that her eyes widened a bit. Certainly there was a perceptible change in her face. It was interest, but it was also certainly more than that. I felt that she would have liked to penetrate the mask of Kennedy's expression, perhaps learn just what facts and theories rested in his mind.

"Is it--" Suddenly she smiled, realizing that Kennedy would reveal only the little which suited his purpose. "Is it something you can tell me?"

she finished.

He shook his head. His answer was tantalizing, his glance searching and without concealment. "Only another detail concerning the chemical a.n.a.lysis of the poison."

"I see!" If she knew of the ampulla the answer would have been intelligible to her. As it was, her face betrayed nothing. "I guess I'll hurry on over alone, then," she added. She extended a hand to each of us. Her grasp was warm and friendly and frank. "So long, and--and good luck, for Stella's sake!"

"h.e.l.lo, folks!"

The dancing bantering voice from behind us, with silvery cadence to its laughter, could belong to no one but Enid Faye. I grasped that it was her car which Kennedy leaned upon. I gasped a bit as I saw her directly at my side, her dainty chamois motoring coat brushing my sleeve, the sun which grew in strength every moment casting mottled shadows upon her face through the transparent brim of her bobbing hat, in mocking answer to the mirth in her eyes.

For an instant she gazed after the retreating Marilyn.

"Good-by, Marilyn! DEAR," she called, mega-phoning her hands.

The other girl made no response. Laughing, Enid slipped a hand under my arm, the firm pressure of her fingers thrilling me. She addressed Kennedy, however.

"Do you want a ride in to the city, both of you?"

Kennedy brightened. "That would be fine! How far are you going?"

"The Burrage. I have a luncheon engagement. That's Forty-fourth."

"Can you drop us off at the university?"

"Surely! Climb in. It's a tight fit, three in the seat, but fun.

And"--facing me--"I want Jamie between us, next to me!"

As we rolled out of the studio inclosure she leaned forward on the wheel to question Kennedy.

"What did Marilyn Loring want? You seemed in deep confab!"

"She volunteered to initiate us to McCann's, across the street."

"Oh!" She skidded about a corner skillfully. "And--"

"Well, we b.u.mped into an additional piece of evidence and I thought Jameson and I ought to hurry in to my laboratory instead."

"I bet"--Enid giggled, readjusting her hat in the breeze--"I bet she wanted to know what you'd found, right away. Didn't she?"

"Yes!" Kennedy's face was noncommittal, "Why do you say that?"

"Because she came into my room, just as we were getting ready for work this morning. Perhaps I'm wrong, but from the way she kept asking me questions about everyone from Manton down I got the idea she was quizzing me, to see how much I knew. Of course this is only my first day, but it seems to me that Marilyn is talking a great deal, without saying very much. I've come to the conclusion she knows a good deal more than she is telling anyone, and that she'd like to find out just how much everyone else knows."

Kennedy nodded almost absent-mindedly, without responding further.

"Well"--Enid speeded up a bit--"not to change connections on the switchboard, I think I'm going to like it with Manton Pictures."

"Will they do justice to your work," Kennedy inquired, "putting you in a partially finished picture in this way?"

"That's where I'm in luck, real bang-up luck. Werner has directed me before and knows just exactly how to handle me."

"What about the story? That was built for Stella, wasn't it?"

"Yes, but they're changing it here and there to fit me. Larry knows my work, too! That's luck again for little Enid."

"How long have you known Millard?" In a flash I realized Kennedy's cleverness. This was the fact he had wished to unearth. The question was as natural as could be. He had led up to it deliberately. I was sure of that.

"Four, nearly five years," she replied, unsuspiciously. Then suddenly she bit her lip, although her expression was well masked. "That is,"

she added, somewhat lamely--"that is, in a casual way, like nearly everyone knows nearly everyone else in the film game."

"Oh!" murmured Kennedy, lapsing into silence.

I BECOME A DETECTIVE

Important as it was to watch Enid and Marilyn, Werner and the rest, Kennedy decided that it was now much more important to hold to his expressed purpose of returning to the laboratory with our trophies of the day's crime hunt.

"For people to whom emotion ought to be an old story in their everyday stage life, I must say they feel and show plenty of it in real life," I remarked, as Enid set us down and drove off. "It does not seem to pall."

"I don't know why the movie people buy stories," remarked Craig, quaintly. "They don't need to do it--they live them."

When we were settled in the laboratory once more Kennedy plunged with renewed vigor into the investigation he had dropped in the morning in order to make the hurried trip to the Phelps home in Tarrytown.

I had hoped he would talk further of the probabilities of the connection of the various people with the crime, but he had no comment even upon the admission of Enid that she had known Millard for a period long antedating the trouble with Stella Lamar.

It seemed that, after all, he was quite excited at the discovery of the ampulla and was anxious to begin the a.n.a.lysis of its scale-like contents. I was not sure, but it struck me that this might be the same substance which had spotted the towel or the portieres. If that were so, the finding of it in this form had given him a new and tangible clue to its nature, accounting for his eagerness.

I watched his elaborate and thorough preparations, wishing I could be of a.s.sistance, but knowing the limitations of my own chemical and bacteriological knowledge. I grasped, however, that he was concentrating his study upon the spots he had cut from the portieres, in particular the stain where the point of the needle had been, and upon the incrustations on the inner surface of the tube. He made solutions of both of these and for some little time experimented with chemical reactions. Then he had recourse to several weighty technical books. Though bursting with curiosity, I dared not question him, nor distract him in any way.
