Rettelse af grammatik og kommaterings-fejl

Hej, 

Er der nogen, der vil hjælpe og rette min lille engelsk-tekst? Jeg har selv rettet de fejl, jeg kunne finde, men jeg ved ikke, om der gemmer sig flere.

På forhånd tak 

Nobody had ever succeeded in catching any of the Landyke-boys except for the twins who caught the Sheriff’s son and kept him, until he promised to loan them the “Earl of Monte Christo”, which was not available on the library. Someone says that the book never had been there other said that the book had been stolen. The twins were active in many ways. They were good to draw, and they drew pictures of the other boys, of the old Miss Jennifer and the animals in their father’s store, before they were cut into pieces. Their father was butcher, and their grandfather had been butcher. Mr. Tuffield’s meat was better and cost less than in Pentonville, and the customers paid immediately or later, as they wanted. The boys were not allowed to come in the store, unless when they had to feed the two dogs, as they obviously fed with good things from the back room. The boys became – with a neutral expression – called lively. Miss Jennifer, a strong independent woman that a crocodile would be scared of, feared them. When a bee stabbed her or her key stuck into the lock, was it their fault. Although they said that they were nice and innocent boys, who never did a postman mischief, what undoubtedly was true, because old Travers was the only postman in the village and a friend of both children and dogs.
