Pep followed disconsolately from room to room, keeping out of the way as well as he could. He finally took up his position by the front door and waited. This was the door through which his master always left when he went on important missions. He determined not to be left behind. If it made his mistress feel so badly to have master go away he would go with him, then she would know he would be safe. Of course all this packing meant his master was going away. He had seen it many times before, but why they hurried so, and why every one’s heart ached, he could not imagine.

At last, everything was ready and Thompson and the motor were at the door. The doctor came into the office. Pep saw that his face was very white. The mistress came in also and stood close to him. Her face also was white and she was trembling. Neither spoke for several seconds. Then the doctor took her in his arms and held her tight for at least a minute. Then still without speaking, he set her gently down in the large easy chair and with a sudden motion, slipped out of the front door with his suit case.

He went so suddenly that the cry of the mistress and the bang of the door sounded almost together.

The closing door missed Pep’s muzzle by barely an inch. He leaped at it and whined frantically and whimpered as the motor rolled away. Then like the faithful companion and sympathetic friend that he was, leaped into his mistress’ lap to kiss away her tears and comfort her.

She hugged him to her heart and poured out her grief in his sympathetic ears. Of course he did not know just what made her feel so badly, but he snuffled in unison with her and told her as plainly as a dog could that he felt just as badly as she did and that they were fellow sufferers.

Finally, the mistress dried her eyes and went to straighten out the house. Pep lay down upon his favorite rug to think. He did not intend to submit tamely to being left behind in this unceremonious manner.

He thought to such good advantage that when Thompson came back with the motor, he had fully made up his mind. When the chauffeur at last came in after putting up the car, Pep was waiting for him at the front door.

He had his muzzle close to the crack so as to be ready. Thompson had barely opened the door and squeezed partly through, for he had been warned to look out for Pep, when the terrier shot between his legs and with a scurry of feet along the walk, he was gone into the darkness. A second later, he was out on the street running frantically for the depot. Thompson and the mistress whistled and shouted but he paid no attention to them, and they saw him disappear twenty rods away around a corner, running like the wind.

“He’s gone after the doctor. The little cuss has gone to war,” cried Thompson. “What shall we do? The doctor told me half a dozen times to-night to keep an eye on him.”

“Take the motor and follow to the station. He can’t go further than that.” So for the second time that night, the doctor’s machine whizzed away to the depot.
