Max had his target in sight. He had been following Duke for quite some time now. The Newfoundland mix lumbered along the sidewalk, completely unaware that he had a shadow.

Looking around, Max recognized the route. This was the same route he and Duke used when they went to his old home. They had already passed that sausage factory and were now in the suburbs. Max knew that whatever Duke was doing had something to do with his old owner Fred. But what exactly?

At last, they arrived at the street. Max could see Duke's old home up ahead. It was only a matter of time before the mutt turned left and entered the yard. The terrier was confused. There was nothing for Duke here. Fred was gone, a new family and a mean Himalayan cat lived there. What could he possibly be doing.

Then Max received a shock when Duke walked right past his old home.

"Duke, what in the name of heck are you doing?" Max wondered aloud. Determined to find out what was going on, the Jack Russell terrier picked up his pace. At this point, he didn't care if he was seen. He watched as Duke continued three more houses. The mutt then stopped at the third one and walked up to the front door. He reached up and rang the doorbell.

A moment later, the door opened.
