1. We've got your son. 2. The doy is safe. 3. You must pay us $500000. 4. He can go when we've got the money. 5. He will be all right. 6. The money must be in $20 notes. 7. Bring BMW and the money (я так понимаю это подразумевалось под many) to the car park. 8. The car should be of red colour. 9. Don't show this letter to the police. 10. Don't spy on us. 11. You'll be sorry if you talk to the police. Я исправила некоторые ошибки в словах, не знаю нужно было или так подразумевалось что люди глупые которые писали письмо.
