"My dear sir," said I drily. "Every man in these days seems to be his own doctor. Try it, and if it's only satisfactory enough, we'll have a beautiful post-mortem to-morrow."
"Well," said little Pye, with a return of his native repartee, "it's precisely because I don't want to be my own doctor that I've come to you."
That naturally was unanswerable, and I acknowledged the hit by prescribing for him. Then I went on my way.
The door was open and the boatswain was waiting. He covered a yawn as I approached.
"It was that fool, Reilly, sir," he explained. "He mucked my instructions."
I nodded and proceeded to examine my patient. The boatswain seemed to have spoken the truth, for the man was as quiet as a log, save for the movement of the clothes when he respired. But it was that very respiration that arrested my attention. I felt his pulse, and I took the temperature. As I moved to examine the glass, Pierce's thin crimson face, peeping over my shoulder, almost struck upon me. The jaw was sucked into its socket. The temperature was still high, too high to allow of that placid sleep. I contemplated the thermometer meditatively. The port was shut, and the only sounds that broke the night were the dull beating of the screw and the duller wash of the waves against the side of the Sea Queen. The boatswain stood motionless behind me.
"You are right," I said slowly. "He has gone off pretty comfortably, but I should like to see his temperature lower. However, the sleep will do him good, and I've no doubt I'll find him all right in the morning."
As I spoke I turned away with a nod and passed out of the cabin. Once on deck, I paused to consider what I should do. Two things I knew for certain: firstly, that the knife-wound was no accident, for no mere horse-play could have resulted in such a deep cut; secondly, that Adams was under the influence of a narcotic. Who had administered it and why? I recalled the man's delirium and his wandering statements to which at the time I had paid little heed, and I thought I began to get the clue. I looked at my watch and found it half-past twelve. Every one, save those on duty, was abed, and the steamer ploughed steadily through the trough, a column of smoke swept abaft by the wind and black against the starlight. I sought my cabin, poured myself out a stiff glass of grog, and sat down to smoke and think.
At two bells I roused myself and went on deck. How singularly still was the progress of the vessel! I heard the feet of the officer on the bridge, and no other sound in all that floating house. A figure like a statue stood out in the dimness by the chart-house, and I came to a pause. It turned, and I thought I made out my friend the quartermaster.
"That you, Ellison?" I asked.
"Yes, sir."
"I want to look at that man Adams in the forecastle," I said. "Please accompany me, as I may need your assistance."
I descended the ladder and went forward till I reached the cabin which I had used as a hospital, and turned the handle of the door. It opened, but the darkness was profound, and Ellison struck a match and lit the lamp. Adams lay in his bunk groaning faintly. I turned up his sleeve and examined him. The wound was inflamed, as I had expected, and it was not that which arrested me, but a mark on the arm above the elbow. It was the prick of the hypodermic syringe. My doubts were now certainties.
As we stood there Adams opened his eyes, and struggled into a sitting posture.
"No, my man," said I, "you must keep to your back."
He stared at me, but allowed me to force him backwards, and continued to stare.
"Adams, can you understand?" said I firmly. "Gray struck you with a knife?"
"Between the shoulders, damn him," he growled sulkily. "Doctor, my head's bad—give me something to drink."
I had come prepared, and I did so, and he fell back with a sigh, showing more signs of alertness.
"You quarrelled?" I suggested, but he made no answer. "Look you here, my man," I went on sternly, "I know a good deal about this, and what you quarrelled over. It would be wiser, believe me, to be candid. Pierce had a hand in this."
Still he was silent. I pulled from my pocket a syringe, and showed it to him.
"Do you know what that is?" I asked.
He shook his head, staring.
"Well," said I, "it came pretty near finishing you off. You have had a heavy dose. I want to know who did it." I caught up his arm, and thrust the puncture under his nose. He still stared.
"You were talking pretty wildly in your delirium, and had to be silenced. That was how it was done. If they can't silence you one way they will another. How much was your share to be?"
The man's face worked in an ugly fashion, and he was at any time a repulsive creature. The glitter in his eyes spoke of fever.
"The devil's own," he said hoarsely. "They wanted to cheat me of it, and I said I'd split. Damn Pierce, and Gray, and all!"
"So you were going for the prince's cash-box, were you?" I said equably.
"It's more than that," said he. "There's the treasure in the strong-room. That's their game."
"Now I see you are sensible," I said, "and I can undertake to make you well and sound and happy provided you tell the truth."
"Doctor, it burns like fire," he groaned.
"I will see to that," I said. "What is the plot?"
"I have cried off. That's why I got the knife," he said faintly. "But swear to God no harm'll come to me."
"I promise you that," I said, nodding.
"It's the boatswain's plot," he whispered, "and he has more'n half the men. They are going to rise ere ever we get to Buenos Ayres. But I was no party to their plans," he continued feverishly, and as if anxious to convince me, "that's why I've this knife, doctor, because I'm an honest man."
I had more than my doubts of that, but I nodded again.
"You have only done your duty in telling me, Adams," said I, "and I'll keep my promise, provided you hold your tongue about this. They have given you a dose of morphia, and it's lucky it wasn't bigger. If you do what I tell you, we'll have you right in a couple of days."
I made him drink a draught I had brought with me, and, closing the door, left him. A passage led from here to the men's quarters, and as I came out, I signed to Ellison to be noiseless, and put out the light. Then we moved towards the hatchway. When we reached it I happened to glance round at Ellison, and through that brooding darkness, lightened only by a dim swinging lamp, I thought I saw a flitting shadow. But the next swing of the boat threw the light clear into the corner, and there was nothing. We emerged on the lower deck, and thence regained the quarterdeck. There was a bright light in the chart-room, and I led the way thither. I closed the door and turned on the quartermaster. His face was grey, and his hand trembled.
"You heard?" said I.
"Yes, sir," he replied, and hesitated. "But he's wandering, sir, ain't he?"
"My man," said I, "I'm a doctor—leave that much to me. I only want to know if you heard. That is all your part. No, there is one thing more. What about the hands?"
"They're a pretty mixed lot, sir, not exactly what I would call yacht hands, but–"
"Were you engaged with them?" I interrupted sharply.
"No, sir, Sir John he got me on. I've sailed with him before."
"Thank the Lord for that," I said heartily, for I had begun to suspect every one. The voyage was a nightmare, I thought.
"Who is the officer in charge?" I asked.
"Mr. Legrand, sir," said Ellison.
The second mate and I had had few exchanges. He was a reserved man, and devoted to his duty. Besides, as navigating officer he had his full share of responsibility for the safety of the ship. I moved out of the chart-house, leaving the quartermaster in a maze of bewilderment, and, I think, incredulity. The stars illumined the figure of the second officer on the bridge, and I stood in a little gust of doubt which shook me. Should I sleep over the new discovery? I had Ellison, a Didymus, for witness, but I was still sore from the reception of my previous news. I took the length of the deck, and looked over the poop where a faint trail of light spumed in the wake of the ship. Suddenly I was seized from behind, lifted by a powerful arm, and thrown violently upon the taffrail. It struck me heavily upon the thighs, and I plunged with my hands desperately in the air, lost my balance, and pitched over head foremost towards the bubbling water.
