He knew the Black Doctor was speaking to him, but he didn't try to reply. He had known from the moment the surgeon came out of the operating room that he was in trouble. It was just a matter of time before he would have to answer for his decision here, and it was even something of a relief that the moment came sooner rather than later.

And the more Dal considered his position, the more indefensible it appeared. Time after time he had thought of Dr. Arnquist's words about judgment and skill. Without one the other was of little value to a doctor, and whatever his skill as a surgeon might have been in the Moruan operating room, he now realized that his judgment had been poor. He had allowed himself to panic at a critical moment, and had failed to see how far the surgery had really progressed. By deciding to wait for help to arrive instead of taking over at once, he had placed the patient in even greater jeopardy than before. In looking back, Dal could see clearly that it would have been far better judgment to proceed on his own.

But that was how it looked now, not then, and there was an old saying that the "retrospectoscope" was the only infallible instrument in all medicine.

In any event, the thing was done, and couldn't be changed, and Dal knew that he could only stand on what he had done, right or wrong.

"Well, I'm waiting," Black Doctor Tanner said, scowling at Dal through his thick-rimmed glasses. "I want to know who was responsible for this fiasco, and why it occurred in the first place."

Dal spread his hands hopelessly. "What do you want me to say?" he asked. "I took a careful history of the situation as soon as we arrived here, and then I examined the patient in the operating room. I thought the surgery might be over my head, and couldn't see attempting it if a hospital ship could be reached in time. I thought the patient could be maintained safely long enough for us to call for help."

"I see," the Black Doctor said. "You've done micro-surgery before?"

"Yes, sir."

"And organ transplant work?"

"Yes, sir."
