Я опять с проверкой
Прямую речь в косвенную)

Исходный:
"Has your sister found a job?" - Boylan asked.
"I don't know", Rudolph said, keeping all the information to himdelf. "I haven't heard from her recently".
"Do you think she'll be successful?" Boylan asked. "Does she have talent?"
"I think so. She has something", answered Rudolph.

Что получилось у меня:
Boylan asked if his sister had found a job.
Rudolph said that he didn't know(n?) and was keeping all the information to himself that he hadn't heard from her recently. (Тут я сомневаюсь с "keeping ... ", где его именно употребить надо.)
Boylan asked if he thought that she would be successful and she had talent.
Rudolph answered that he thought so and she had something.

Старался делать по правилам, но всё-таки.) Если что где неправильно, просьба объяснить.)
