Little Choo wants to be just like his father Papa Pufferbelly, but pulling a line of freight cars up a steep mountain might be a little too much for the small engine.

Hank, a retired Sergeant with the Military Police, receives a call informing him that his youngest son, Mike, has gone AWOL. He thought his son was in Iraq, but is informed that Mike returned stateside four days ago with his platoon. When he calls his son's cell phone and gets voice mail, he drives to Fort Rudd and begins to make inquiries, but with each inquiry he comes to a dead end. Then a body is found, dismembered and burned beyond recognition...

Follows the seaside adventures of Henry, Henry's father, and Henry's big dog Mudge.
