Part 5 (1/2)

”And for good reasons, too,” remarked the doctor. ”For if I really believed the circ.u.mstances warranted the step it would be my duty to communicate my suspicions to the coroner.”

”Then you haven't done so!” I was surprised and doubtless my voice showed it.

”No,” a.s.sented Marcy deliberately. ”In the first place I was determined to keep every

I started; I fancied that I had caught just the faintest suggestion of a sigh. Let me explain that the great room was in darkness except for the circle of yellow light cast by the shaded lamp that stood on a table at my right. I listened intently, but I could hear nothing more.

_The Missing Link_

”I beg your pardon,” repeated Doctor Marcy, looking at me uncertainly.

”I should beg yours, doctor,” I answered as easily as I could. Some sixth sense had made me aware that Betty Graeme was standing in the shadow behind me. She must have heard more than enough already, and now she would demand the whole truth. a.s.suredly I must protect her in her evident desire to remain unnoticed.

”I didn't mean to interrupt,” I continued, ”but my cigarette was burning my fingers--too much interested, you see.”

”Secondly, then,” went on Doctor Marcy, ”I have found the missing 'something' that serves to link up the chain.”

The doctor took a small key from his waist-coat pocket and proceeded to unlock a compartment in the great, flat-topped desk, the latter constructed after the usual design with a set of drawers, and other storage places, on either side of a central well for the accommodation of the writer's feet and legs. From this compartment he unearthed a despatch box made of iron, an old-fas.h.i.+oned piece that might have come down from Revolutionary days. It measured about fifteen inches, by ten, by seven; and the corners were bound in bra.s.s.

”Yes, it could have done the business without a doubt,” said Marcy, answering my unuttered question. ”The box must have been standing on the floor near the screen. Francis Graeme rises, perhaps with the intention of picking it up. He suffers a cerebral rush of blood, becomes dizzy, falls, and strikes his head against this sharp corner. A severe blow in the region of the temple may be instantaneously fatal.”

There was a rustle of feminine garments, and my Cousin Betty came from behind the screen and stood before us. ”There is only one flaw in your argument, doctor,” she said, with just the thin edge of a tremor in her high, sweet voice. ”Where was that box when you first came in the room and knelt by my--my father?”

”Sorry you had to know, my girl,” said the doctor; he had risen and was standing close to her, holding both her hands in his own big, warm palms. ”Sorry you had to know,” he repeated. ”But since it has come about I shan't be keeping anything back. I wanted to spare you.”

”Yes, I understand that,” she returned, ”and I'm grateful, too. Yet after deciding that an inquest is not necessary, after signing a certificate that death was due to natural causes, you're not satisfied in your own mind. I come in here and find you telling my Cousin Hugh that there is some mystery in the affair, that all is not straight and aboveboard. You even offer a perfectly plausible explanation of what--of what really happened. Yes, and I would have accepted it like everyone else--only for one thing----”

”Yes?” queried the doctor.

”I'll put my question again. Where was that iron despatch-box when you first entered the room, and saw--well, what you saw?”

Doctor Marcy waited a moment or two before replying. ”There isn't any doubt in my mind,” he began, ”but that your father did fall and that the contusion on his forehead was caused by that actual iron box. I confess that I didn't notice it when I first saw the body and knelt down to feel the pulse. I a.s.sume that it had been accidentally pushed out of sight in the angle formed by the screen and the desk; it was just there that I found it later on.”

”On your second visit to the room?”

”Yes.”

”Well, suppose you tell Cousin Hugh what you were doing in the interval.

I want to see if his mind will work in the same direction as mine.”

”I had stepped into the hall just in time to see you riding up the green drive,” said the doctor, ”and I realized that someone must prepare you for what had happened. I asked Miss Trevor to do it, but she insisted that she could not go through the ordeal. Consequently, I put Effingham on guard at the library door with instructions to let no one pa.s.s; then I went down to the horse-block and a.s.sisted you to dismount. You saw instantly that something was wrong, and you begged me to tell you the truth. But I would not say a word until we were in the parlor. Then I admitted that your father had met with an accident. Before I could prevent it you had rushed into the hall and down to the library door.”

”Go on,” ordered Betty, as he hesitated. ”Tell Cousin Hugh who was standing there.”
