Как можно сократить этот текст (только самое главное)? Помогите, пожалуйста. Нужно выучить, а мне это много учить.

When James Bond got back to his hotel room it was midnight. His windows were closed and the air-conditioning was on. Bond switched it off and opened the windows. He breathed in the air with relief, then had a shower and went to bed.
At 3.30 he was dreaming, not very peacefully when suddenly he woke up. He listened. There was a noise. It was coming from the window. Someone was moving behind the curtains. James Bond took his gun from under his pillow, got quietly out of bed, and crept slowly along the wall towards the window. Someone was breathing behind the curtains. Bond pulled them back with one quick movement and saw a blond.
'Mary Goodnight!' Bond cursed. 'What the hell are you doing here?'
'Quick, James! Help me in!' she whispered.
Bond put down his gun and tried to pull her through the open window. At the last moment her foot was caught in the curtain and the window made a loud noise. Bond cursed again.
Mary Goodnight whispered, 'I’m terribly sorry, James!'
'Sh! Sh!' said Bond, and quickly led her across the room to the bathroom. He turned on the light and the shower. They sat down on the side of the bath. Bond asked again. 'What the hell are you doing here? What's the matter?'
'James, I was so worried. A message has come this evening. A top KGB man, using the name Hendriks, is staying at this hotel. I knew you were looking for him, but he knows you're here. He's looking for you!'
'I know,' said Bond. 'That man's here right now. Mary, did they say if he has got a description of me?'
'No, he hasn't. You were just described as secret agent James Bond.'
'Thanks, Mary. Now I must get you out of here. Don't worry about me, OK?
'OK, James.' She stood up and looked into his eyes: 'Please take care, James.'
'Sure, sure.' Bond turned off the shower and opened the bathroom door. 'Now, come on.'
A voice came from the darkness of the bedroom: 'This is not your lucky day, Mr Bond. Come here both of you. Put your hands behind your necks!'
Scaramanga walked to the door and turned on the lights. His golden gun was pointing directly at James Bond.
