"Very well," he said, making no move to follow me.
I shook my head doubtfully. It was impossible to force a card on Kennedy. Instead of showing any disposition to switch off the laboratory lights, he appeared to be regarding a row of half-filled test-tubes with the abstraction of a man who has been interrupted in the midst of an absorbing occupation.
"Good night," I said at length.
"Good night," he echoed mechanically.
I know that he slept that night—at least his bed had been slept in when I awoke in the morning. But he was gone. But then, it was not unusual for him, when the fever for work was on him, to consider even five or fewer hours a night's rest. It made no difference when I argued with him. The fact that he thrived on it himself and could justify it by pointing to other scientists was refutation enough.
Slowly I dressed, breakfasted, and began transcribing what I could from the hastily jotted down notes of the day before. I knew that the work, whatever it was, in which he was now engaged must be in the nature of research, dear to his heart. Otherwise, he would have left word for me.
No word came from him, however, all day, and I had not only caught up in my notes, but, my appetite whetted by our first case, had become hungry for more. In fact I had begun to get a little worried at the continued silence. A hand on the knob of the door or a ring of the telephone would have been a welcome relief. I was gradually becoming aware of the fact that I liked the excitement of the life as much as Kennedy did.
