Poor girl, she did not know how fast she was nearing trouble herself. The master, Mr. Dobbins, had reached middle age with an unsatisfied ambition. The darling of his desires was, to be a doctor, but poverty had decreed that he should be nothing higher than a village schoolmaster. Every day he took a mysterious book out of his desk and absorbed himself in it at times when no classes were reciting. He kept that book under lock and key. There was not an urchin in school but was perishing to have a glimpse of it, but the chance never came. Every boy and girl had a theory about the nature of that book; but no two theories were alike, and there was no way of getting at the facts in the case. Now, as Becky was passing by the desk, which stood near the door, she noticed that the key was in the lock! It was a precious moment. She glanced around; found herself alone, and the next instant she had the book in her hands. The titlepage--Professor Somebody's _Anatomy_--carried no information to her mind; so she began to turn the leaves. She came at once upon a handsomely engraved and colored frontispiece--a human figure, stark naked. At that moment a shadow fell on the page and Tom Sawyer stepped in at the door and caught a glimpse of the picture. Becky snatched at the book to close it, and had the hard luck to tear the pictured page half down the middle. She thrust the volume into the desk, turned the key, and burst out crying with shame and vexation.

"Tom Sawyer, you are just as mean as you can be, to sneak up on a person and look at what they're looking at."

"How could I know you was looking at anything?"

"You ought to be ashamed of yourself, Tom Sawyer; you know you're going to tell on me, and oh, what shall I do, what shall I do! I'll be whipped, and I never was whipped in school."

Then she stamped her little foot and said:

"_Be_ so mean if you want to! I know something that's going to happen. You just wait and you'll see! Hateful, hateful, hateful!"--and she flung out of the house with a new explosion of crying.

Tom stood still, rather flustered by this onslaught. Presently he said to himself:

"What a curious kind of a fool a girl is! Never been licked in school! Shucks! What's a licking! That's just like a girl--they're so thin-skinned and chicken-hearted. Well, of course I ain't going to tell old Dobbins on this little fool, because there's other ways of getting even on her, that ain't so mean; but what of it? Old Dobbins will ask who it was tore his book. Nobody'll answer. Then he'll do just the way he always does--ask first one and then t'other, and when he comes to the right girl he'll know it, without any telling. Girls' faces always tell on them. They ain't got any backbone. She'll get licked. Well, it's a kind of a tight place for Becky Thatcher, because there ain't any way out of it." Tom conned the thing a moment longer, and then added: "All right, though; she'd like to see me in just such a fix--let her sweat it out!"
