chunk: The protagonist teaches a dog, Bellona, to do one thing and one thing only, retrieval, with emphasis on water retrieving and taking the stick back to the thrower no matter where they were. Claverhouse is presented with Bellona before his upcoming trout fishing trip. The protagonist observes from a distance with glee as Claverhouse lights a stick of dynamite and throws it into the water. Bellona, trained to retrieve, fetches the explosive. Claverhouse runs from the dog in futility until "just as she caught up, he in full stride, and she leaping with nose at his knee, there was a sudden flash, a burst of smoke, a terrific detonation, and where man and dog had been the instant before there was naught to be seen but a big hole in the ground."
  The death is ruled an accident while engaged in illegal fishing. The protagonist takes pride in killing Claverhouse with no mess or brutality and lives in peace.
