Can you proofread the sentences?
1. He climbs out of window sill and lowers himself down to the gardent below using the bed sheet.
2. Roger crawls through/ across the gardend in darkness.
3. As he crawls through/across the water, he sees a woman in black on a motorbike.
Sorry, the sentence of the second sentence should be:
Using a straw to breathe, he swims under the water until he reaches the other side. As he crawls through/across /out of the water, he sees a woman in black on a motorbike.
