It must have been around nine o’clock when I  1   back home from work because it was already dark. As I approached the gate I turned   2   the headlamps of the car   3   prevent the beam from swinging in through the window and   4   Jack, who shared the house with me. But I needn’t have bothered．I noticed that his light was still   5   , so he was awake anyway   6   he’d fallen asleep while reading. I put the car away and went up the steps. Then I opened the door   7   and went to Jack’ s room. He was in bed   8   but he didn’t even turn towards me.

    “What’s up, Jack?” I said.

    “For god’s sake don’t make a noise,” he said.

    The way he spoke reminded me of someone   9   who is afraid to talk in case he should do himself a serious injury.

    “Take your shoes off, Nellille,” Jack said.

    I thought he   10   ill and that I had better humor him to keep him happy. “There’s a snake here,” he explained．“It’s asleep between the sheets. I was lying  11   my back reading when I saw it. I knew that moving was out of   12   I couldn’t have moved   13   I’d wanted to. ” I realized that he was serious. “I was relying on you to   14   a doctor as soon as you came home,” Jack went on. “It hasn’t   15   me yet but I   16   do anything to upset it. It might wake up. I’m   17   of this,” he said．“I   18   you’d be home an hour ago.”

　　 There was no time to   19   for being late. I looked at him as   20   as I could and went out to telephone the doctor.
