Marvin Redpost Alone in his teacher's House

By Louis Sachar

Nick and Stuart think Marvin's the luckiest boy in the world when his teacher asks him to dog-sit for a week. He can go into teacher's house alone. On top of that, he's going to be paid.

In return for teacher's trust, he's determined to complete his duty. He even refuses his best friends' begging to see the inside of the teacher's inside.

I can't say if his mission has been successfully completed or not as it's the part of the climax.

I've read Holes which Louis Sacher wrote and love it. Frankly speaking, I bought almost all of his books since!! No regret.
